Coupled with the influence of "Call for Building a Healthy China", sports short videos with strong interaction and strong appeal have gradually become a new popular category in the field of short videos, and with the participation of more and more creators, they have become popular and diversified.

Li Jianpeng, the creator of "Jianpeng", takes skateboarding as a link to lead the audience into the colorful spiritual world of young people.

　　In addition to expressing the young of different sports, the creators in the program will also refresh the audience’s inherent cognition of some sports and show the audience more possibilities of sports through bold breakthroughs in themselves. For example, Wang Rongchao, the creator of "Martial Arts Practitioner", combines traditional martial arts with underwater performances to create a short video of martial arts with a full sense of film; Rao Zilong, the creator of "Rao Zilong", gives full play to his professional advantages in dance, which makes the simple square dance glow with new interest; Zhang Yijie, the creator of "Zhang Yijie", used the plot to open Parkour, connecting the unpopular movement with the hot life … …

Shi Wei, the creator of "Tiedou", has developed his own "multifaceted life" by challenging different extreme sports.

　　Taking the exhibition video as a prism, the creators’ works with different styles reflect their multi-dimensional attitude towards sports and life. This also aroused strong resonance between the host Nigmat, the special recommender Wang Bingbing of the National (Hangzhou) Short Video Base and the judges.

Who let Deng Yaping, Olympic champion and table tennis grand slam winner, share her inner feelings of winning the championship for the first time emotionally? Whose work makes the singer martial arts talk about interesting sports? Whose works make Gao Ying, Executive Dean of Zhejiang Institute of Cultural Industry Innovation and Development, full of praise?

　　That song "Have money and no money to go home for the New Year" has sung the voices of countless homecoming people.

　　All the way to the dusty, tired, as long as the plunge into the hot "home", a year of hard work is worth it.

　　But I don’t know when, the family reunion has changed its taste, adding a touch of awkwardness of being close to home.

　　Lin Yutang said: "Chinese’s face can not only be washed, but also thrown away, rewarded, contested and kept. Sometimes it seems that fighting for face is the first meaning of life."

　　The more people there are, the more you can’t escape the absurdity of "saving face"

　　01

　　How many people were kidnapped by face during the Spring Festival?

　　Face, the first meaning of visiting relatives and friends during the Chinese New Year.

　　In order to be "decent", it’s painful to punch a swollen face and fill a fat man.

　　1. You are a mature adult. It’s time to learn to pay a good New Year call.

　　The pain of being forced to show "communication skills" is comparable to talent show.

　　No matter how close you are to each other or how deep your friendship is, you have to smile, say hello warmly and take the initiative to greet each other, even if you don’t know the relationship at all.

　　Anyway, pull my parents’ sleeves, smiling mother immediately prompt:

　　This is the second cousin of your third uncle, Grandma Wang, and we are close relatives. According to your seniority, you have to call someone an old aunt!

　　Then, you have to hide your embarrassment with a smile and pretend to be caring and attentive naturally.

　　The days of visiting relatives can be described as the peak period of social phobia patients.

　　In the eyes of many parents, if you can’t greet your relatives and friends warmly, you are guilty of a big taboo, because "giving others a face is giving yourself a face."

　　In Family with Children, Liu Xing’s good friend Mouse went to Liu Xing’s house with her mother.

　　Mother winked and poked at her son. Every time she poked, the mouse said a compliment with a grin on her face.

　　Mouse and Mom/Family with Children

　　Xia Donghai and Liu Mei also had to follow closely, returning an anodyne greeting.

　　Liu Mei and Xia Donghai/Family with Children

　　After several rounds of "full chat", the mother was still not satisfied, poked her son again, and muttered with a mouse:

　　Mouse and Mom/Family with Children

　　The same is true for holidays. I have been struggling for 358 days in complicated social relationships. I finally have 7 days to stay at home and raise my spirit to be "willful", but I still have to deal with the world.

　　A superficial greeting, the same courtesy, the greeting person is exhausted physically and mentally, and the person being greeted is also embarrassed.

　　Liu Xing and Xia Xue/Family with Children

　　In the end, whose dignity was fulfilled?

　　2. "How drunk you can drink means how much you can afford me."

　　Distant relatives I haven’t seen for many years, old classmates I haven’t gathered together for a long time …

　　Common topics are becoming less and less, and the exchange of feelings depends on a glass of wine.

　　Drinking is supposed to be fun, but there are always people who, in order to highlight their appeal, turn drinking into a "mutual test" to keep up appearances and gain prestige.

　　"If you don’t drink, you won’t give me face."

　　"You are embarrassing me."

　　After three rounds of drinking, toasting becomes persuading, and persuading becomes forcing.

　　No one wants to be labeled as "indifferent to feelings" and can only surrender under the coercion of "deep feelings and a stuffy mouth"

　　Drinking a few glasses of wine has become a sign of testing the depth of friendship, which only satisfies the vanity of the drinker.

　　In the eyes of many people, drinking is related to their own face. Not drinking is almost linked to "incompetence", and refusing to drink means "not being brothers enough".

　　In order to be a hero, talk about loyalty, and fight for wine without restraint, it is more than human feelings that are kidnapped.

　　Mr. Shi, 40, dined with his comrades-in-arms for many years.

　　Mr. Shi, who was weak in alcohol, was embarrassed to be a wet blanket and forced himself to drink six bottles of beer.

　　During the dinner, he couldn’t help but want to go to the bathroom to vomit, and he was afraid of being laughed at. As soon as the dirt in his stomach swelled up, he held his breath hard and pressed it back.

　　Finally, Mr. Shi’s abdominal pain was unbearable, and he fell down on the table. After being sent to the hospital for examination, he found that Mr. Shi’s esophagus was "exploded" by the gas of beer.

　　If you want to save face to a certain extent, even "living a life of suffering" is a luxury.

　　At a dinner party in Jinhua, Zhejiang, 10 people advised each other to drink, and one of them was lying in the lobby of the hotel to sleep because of lack of alcohol.

　　By the time everyone came back, he was out of breath.

　　The police introduced Mr. Shi’s misfortune due to excessive drinking/pear video

　　The other nine people who drank at the same table were found to need to pay more than 600,000 yuan to the families of the deceased because they failed to fulfill their dissuasion obligations and failed to send their drunken friends home.

　　For the sake of the so-called face, punching a swollen face and filling it with fat, breaking a tooth and swallowing it in the stomach, at most, it is a temporary pain.

　　If you bet your life and put your health in it, it is really too late to regret it.

　　3. Even if you overdraw, you have to have a "decent year"

　　What are you most afraid of when you go home during the Spring Festival?

　　Endless marriage, birth, comparison and entertainment …

　　At the end of the day, I am most afraid of meeting that "you are so bad" look.

　　People who have worked hard outside for a year return to their hometown with great joy, only to find that the taste of the year is getting weaker and weaker and the taste of money is getting heavier and heavier.

　　A few days ago, there was a hot search on the national lucky money map.

　　Red envelopes of several hundred yuan are normal, but in some places, lucky money has already reached tens of thousands.

　　National Lucky Money Map/Weibo @ Sina News

　　China News Network once made a statistic, how much does it cost to spend a decent year?

　　The result is very heartfelt, and it costs 8900~36000 yuan.

　　Spring Festival spending statistics/China News Network

　　No matter how the year goes, you should at least "pretend" to be decent, so as not to be looked down upon.

　　If you can’t return home with clothes on, you should also "rent" it.

　　Ms. Liu, a white-collar worker in Shanghai, rented a 20,000-yuan bag to go back to her hometown this year. "There are many classmates and family gatherings to attend, and I need a decent bag."

　　The person in charge of the operation of a rental platform revealed, "In the first half of the month, the booking demand of some luxury brands began to rise sharply, but because many users will directly renew their leases, many users have not rented them."

　　It is understandable to show your success and pursue decency. If you deliberately show off, it will change its taste.

　　Netizens lamented the excessive pursuit of decency and the taste of the New Year/Weibo

　　People who really care about you, whether you get ahead or not, will leave a pair of bowls and chopsticks for you to have a hot meal with.

　　Too much care about other people’s eyes, trouble and money to cover up, but failed to live up to this hard-won reunion.

　　02

　　The face piled up by matter is doomed to be fragile.

　　In his autobiography "My First Half Life", Puyi once recalled the luxurious imperial life.

　　Even the daily thing of eating, the royal family can toss out a huge set of ostentation and extravagance, and decorate the decency to the extreme.

　　"The biggest ostentation and extravagance that consumes manpower, material resources and financial resources is eating.

　　I ordered a’ pass the meal!’

　　The little eunuch in front of him said the same thing to the eunuch in the temple on the Ming Temple in hall of mental cultivation,’ Pass the food!’

　　The eunuch in the temple passed this on to the eunuch standing outside Yangxin Gate, and he passed it on to the eunuch waiting in the imperial kitchen in West Strip … So it has been passed into the imperial kitchen.

　　Before the echo disappeared, a procession like a dowry had walked out of the imperial kitchen.

　　This is a team composed of dozens of eunuchs dressed neatly, carrying seven dining tables, holding dozens of red lacquer boxes painted with golden dragons, and heading straight for hall of mental cultivation. "

　　These dishes are just a formality. I don’t know how many times they have been reheated in order to complete the above process.

　　Puyi doesn’t eat these things, but wastes them in vain.

　　Confucius’ phrase "Never tire of eating fine food, never tire of eating fine food" originally emphasized the etiquette of life, but it has changed from generation to generation.

　　The culture of advocating etiquette and norms has created Chinese’s unique face view.

　　The royal family has its own strength to show off its prestige, while ordinary people pretend to be "face-to-face" for the sake of others’ eyes, so they can only eat their own bitter fruit.

　　Some scholars put forward the concept of "status consumption", which means that consumers convey their social status to others and improve their image through conspicuous consumption.

　　In short, it is to spend money to buy face.

　　According to the American magazine Jing Daily, by 2025, the luxury goods purchased by China’s post-90s and post-00s consumers are expected to account for 46% of the global market.

　　At the same time, the debt-to-income ratio of the post-90s generation in China reached an astonishing 1850%.

　　Behind the prosperity of luxury consumption, there is a worrying debt risk.

　　China tourists buy luxury goods/vision china.

　　Mr. Shen Lao, who lives in Shanghai, has a history of uremia for many years and relies on drug treatment to maintain his life.

　　Over half a year old, but I owe 1 million foreign debts.

　　This debt is owed by the adopted daughter.

　　Before that, he had paid off more than 1.3 million debts for his adopted daughter, patched things together and ran around …

　　Shen Lao’s self-report on bitter family affairs/"Case Focus"

　　In July 2017, Mr. Shen Lao’s adopted daughter suddenly disappeared, leaving a "suicide note" that listed all the foreign debts he owed.

　　"suicide note"/"case focus" left by adopted daughter

　　Mr. Shen Lao can’t believe it. The adopted daughter is a kindergarten teacher. How can she spend so much money?

　　According to a friend, Miss Shen spends a lot of money and is keen on buying brand-name clothes, cosmetics and bags.

　　My friend said that Miss Shen loves luxury bags/Case Focus.

　　When I first borrowed money, I just wanted to change my computer.

　　I tasted the sweetness of "decency" and gradually indulged in luxury goods that did not match my income, which gradually ruined a stable life.

　　In "Super Speaker", player Zhang Xiaolei has a thought-provoking passage:

　　Face is the most precious luxury in the world. How many people let go of their own limits and principles for it? They should take care of others’ faces and observe others’ glances.

　　You can build a decent face with materials, but after all, it is still a mirror, deceiving yourself.

　　03

　　Focus on the "lining"

　　Face is as funny as it looks noble.

　　Dou Wen Tao, the host, once filled a venue for the "buddy".

　　Many years ago, an unknown young man went through several layers of relationships and found Dou Wen Tao to help him marry.

　　Dou Wen Tao recalled helping to preside over the wedding/"Round Table"

　　The wedding scene was quite spectacular, and all the local dignitaries were present.

　　Dou Wen Tao also "played enough" and didn’t give a clue.

　　After the banquet, the groom confided to Dou Wen Tao: "This wedding is fake, it is for parents."

　　It turned out that the bride and groom had no intention of getting married.

　　The whole day’s fleet scheduling and luxury brothers lineup are all to show the neighbors who once looked down on the groom’s family how prominent their family is.

　　The so-called wedding is actually a sad farce.

　　"Face this thing can’t be defined. It’s like honor, but it’s not like honor.

　　It can’t be bought with money, it can give men or women substantial pride.

　　It is empty, men fight for it, and many women die for it. It is invisible, but it can exist only by showing it to the public. "

　　Sociologist Erving·Goffman’s parody theory reveals the essence of face: it is the social position or prestige that an individual obtains in society.

　　What many people can’t see through is that a person’s social status and external evaluation do not depend on the external appearance, but on the internal quality that a person has.

　　The evaluation standard of the world is always determined by value, and it is by no means a secular vision.

　　How much weight you have, how much face others will sell you.

　　Calm down and think about it, and you will find that 99% of what happens to yourself every day is meaningless to others.

　　There’s a line in The Master:

　　People live a lifetime, some people become face, some people become lining.

　　"If you don’t return to your hometown with wealth, you will never know." The overlord of the place of Xi Chu, who knows how to save face, will also be ridiculed as "dressed like a monkey."

　　Face is the facade to decorate the lining. As long as it is the facade, it may collapse in an instant.

　　As a "lining", the inner cultivation and personal qualities are invisible and intangible, but they really support a person’s solid spine.

In December 1930, the Red Army captured the "half radio station" of the Kuomintang army.

foreword

The People’s Signal Corps started from the captured half of the radio station and grew rapidly in the war, becoming an important combat force of our army. Red radio waves transmit the party’s voice and issue the party’s orders, which plays a vital role during the revolutionary war. From the agrarian revolution in single spark can start a prairie fire to the arduous Long March, from the war-torn War of Resistance against Japanese Aggression to the magnificent war of liberation, and then to the war to resist U.S. aggression and aid Korea, red radio waves ensured the battlefield command and communication and ensured the coordinated and efficient actions of our army; Opened up a hidden battlefield and strengthened intelligence reconnaissance and confrontation against the enemy; Establish a publicity window for public opinion and expand the political influence of our party and army. In order to let more readers know about the development history of our army’s signal soldiers and radio undertakings, this edition has launched a series of manuscripts of "Never-Gone Red Radio Waves" from today, so please pay attention.

In 1931, the first radio communication team of the Chinese Workers and Peasants Red Army was established in the Central Soviet Area. Since then, the Red Army has used battlefield capture, class training and real-time application to overcome the difficulties of radio equipment shortage, lack of communication talents and lack of experience in application, and has developed and strengthened the radio communication cause of our party and army, providing effective information and communication guarantee for the central government to make decision-making arrangements and the troops to move flexibly and quickly, which is of great significance for breaking through the enemy’s military blockade and winning the war.

"Half Radio Station" lays the foundation

When organizing the "encirclement and suppression" of the Red Army, the Kuomintang already owned a long-wave radio station and used Morse code to send messages, while the Red Army mainly relied on sports communication and simple signal communication such as riding horses, messengers, whistles and bugles. Mao Zedong once said with emotion, "Without radio communication, the troops could not communicate, which seriously affected the operational command". Since October 1930, Chiang Kai-shek has mobilized more than 100,000 troops to carry out the first large-scale "encirclement and suppression" of the Central Soviet Area. At the end of December, two brigades of the 18th enemy division went deep into Longgang, the hinterland of the Soviet area. During the battle, the Red Army took advantage of the enemy’s shaky foothold, seized the favorable fighter plane, concentrated its superior forces to wipe out the enemy in one fell swoop, captured its teacher Zhang Huizan alive, and seized a 15-watt radio station with a spring lamp holder. The receiver and charger of the radio station were in good condition, but the transmitter was damaged and normal communication could not be carried out. Radio operators such as Wang Qian, Wu Rusheng, Wei Wengong, Liu Yin and Liu Shengbing, who were mobilized to join the Red Army voluntarily, became the first operators of the Red Army. Three days later, the Red Army annihilated the enemy’s 50th Division in the battle of Dongshao and seized an intact 15-watt radio station. On January 3, 1931, Mao Zedong and Zhu De cordially received Wang Chen and others, and ordered Wang Chen to set up the first radio station team of the Red Army. Zhu De pointed to the captured radio station and said, "No matter what weapons and equipment the White Army has, the Red Army will have them. If not, the enemy will’ send’ them to us."

On January 6, 1931, the East Room of the General Staff Office of the Red Army was arranged as a "newspaper room", and Wang Chen and others installed and tested this radio station for the first time. At this time, this radio station cannot establish radio communication, and can only be used to copy the news and telegrams of the Kuomintang Central News Agency. After debugging, the radio station received the first speeding radio wave. Mao Zedong praised the telegraph news sent by the radio for the first time: "This is a newspaper without paper!" Since then, the Red Army began to use this radio station to capture enemy radio signals and understand the enemy’s movements, which provided a strong guarantee for the Red Army to grasp the fighters, make correct decisions and win by surprise.

In mid-January, 1931, the Red Army set up its first radio team in Xiaobu Town, Ningdu, Jiangxi Province, with Wang Chen as the captain and Feng Wenbin as the political commissar. Later, the Central Committee of the Communist Party of China sent Wu Yunfu, Zeng San and Tu Zuochao from Shanghai to the Central Soviet Area to strengthen the radio team. Mao Zedong, Zhu De and other leading comrades attached great importance to and strongly supported radio work. Zhu De almost goes to the radio station after supper every day to ask if there is any news. Mao Zedong also attaches great importance to radio communication. In the third anti-encirclement campaign, the Red Army assembled from western Fujian to Xingguo in southern Jiangxi. In order to break through the encirclement of the enemy, it was necessary to use the night to jump out from the gap about 20 kilometers apart between the two enemies. After the operation began, commanders and political cadres at all levels went deep into the company and demanded strict confidentiality of the operation. As the general political commissar of the Red Army, Mao Zedong is keenly aware that there is another loophole that may expose the whereabouts of the Red Army in the night-the radio signal of the radio station. He immediately asked the radio staff and learned that the radio station could not work without the key. So he sent someone to collect the call keys and give them to the guards and told them: No one is allowed to take them away until they reach their destination!

In view of the technical personnel who used to work in the Kuomintang army, Mao Zedong repeatedly instructed that we should do a good job in the unity of radio personnel, trust them politically, and even personally appointed Wang Wei to attend the Soviet Congress. For the business management and living arrangements of radio technicians, even if the Red Army was short of funds and supplies at that time, the monthly allowance for radio technicians was only much more than that of ordinary soldiers, and transport horses were given priority. With the concern of the Red Army leaders, the radio communication team has gradually grown.

Cultivate talents from scratch

After the establishment of the red army radio team, it mainly relied on retaining the technical personnel of the former Kuomintang army. The headquarters of the Red Army realized that in order to give full play to the role of radio stations, radio technicians were urgently needed. On January 28th, 1931, Mao Zedong and Zhu De jointly issued the Order of Selecting and Transferring Students to Learn Radio, and organized the first radio training in Ningdu, Jiangxi. Mao Zedong, Zhu De and other Red Army leaders often take time out to make situation reports and give political lessons to training classes. Mao Zedong encourages everyone to build an air bridge as soon as possible to connect the divided Soviet areas with radio waves. Zhu Deze encourages everyone to be not afraid of difficulties in building the Red Army’s radio communication career. At that time, the teaching conditions of the training class were very simple. The students used the shade as a classroom, the slate as a table, and the thumb of their left hand as an electric key to practice. The pencils could not be pinched with their fingers, and they were put on a small bamboo tube to continue to use. In four months, Wang Chen taught telegraphy and maintenance for the students, made electric keys from wood blocks and iron sheets, and made training equipment such as code trainers from old copper wires for 17 students to practice, and trained the first batch of radio communication personnel.

At that time, due to the tight blockade of the Central Soviet Area by the Kuomintang, the material conditions for the production of communication equipment were difficult. Wang Chen mobilized everyone to use local materials, smelt copper coins into thin copper plates for processing and manufacturing electrical components, and ground the horns into powder and pressed them into bakelite substitutes. With the unremitting efforts of the officers and men of the radio team, the Red Army finally formed the the Central Committee of the Communist Party of China Radio Communication Network.

Since then, the training team has been expanded into the Red Army Communication School. Until the eve of the Long March, 11 radio training courses have been held, which have trained more than 2,100 communication personnel in telegraph, maintenance, telephone, company number and semaphore, which has had a far-reaching impact on the future development of China revolution.

Make a name for yourself in the fight against "encirclement and suppression"

In the complicated and fierce struggle against "encirclement and suppression", Wang Chen proposed that the telegraph could be used to intercept enemy electricity to obtain information. He asked the communication class to put the antenna on the top of the mountain after dark to improve the communication effect and withdraw it before dawn to avoid exposure. At that time, the Kuomintang army’s telegraph translator and commander had not realized the importance of radio secrecy. Every time the radio station started to contact, they asked the other party where and who was in the main direction. Wang Chen and the members of the radio communication team listened and captured the useful information of the enemy radio station day and night. Wang Chen is familiar with the call sign of the Kuomintang army radio station and the methods used by radio operators to send telegrams, so he can judge the name of the sender from the signal of the receiver, and then judge the arrival time, place, serial number, distribution and action intention of the enemy, and master the information of the enemy’s action direction, retreat route, arrival position and command order, which provides an important basis for the leaders of the Red Army headquarters to make strategic decisions. Relying on this important information, the Red Army concentrated its forces and made a breakthrough from the relatively weak enemy forces, which directly contributed to the great victory of the second and third counter-campaign against "encirclement and suppression".

The Red Army’s good news came frequently, and Mao Zedong said happily in the military-civilian rally in the Soviet area, "We, the Red Army of workers and peasants, also have clairvoyance and ears.". In May, 1931, the Red Army seized a 100-watt radio station of the Gong Bingfan Department of the Kuomintang Army in the second anti-encirclement campaign. Radio technicians got in touch with the Central Committee of the Communist Party of China through this radio station. On November 7, 1931, the first National Congress of the Chinese Soviet opened in Yeping Village, Ruijin, Jiangxi. In several earthen houses not far from the meeting place, technicians of the Red Army Radio Station, such as Wang Chen and Liu Yin, broadcast the text through the previously seized 100-watt radio station. The news that the first national congress of the Chinese Soviet was held in Ruijin soon turned into airwaves and spread to the distance. The earliest news agency "Red China News Agency" (the predecessor of Xinhua News Agency) established by the Communist Party of China (CPC) in the revolutionary base area was announced. For the first time, our party crossed the enemy’s "iron wall" through radio, and announced to the whole country the good news of the establishment of the provisional central government in chinese soviet republic and the election of Mao Zedong as the chairman of the provisional central government, which spread the good news of victory to the people of the whole country.

In addition to improving body muscle shape, exercise is more an effective health intervention, which is related to the reduction of the risk of chronic metabolic diseases such as obesity, diabetes and cardiovascular diseases.

However, it is easy to say that "exercise is good for physical and mental health", but it is difficult to explain the mechanism. There are still many unsolved mechanisms of exercise on systemic metabolic health. For example, a recent study shows that, but researchers have not directly proved the specific benefits of exercise to the liver [1].

This time, the team of He Congcong from Northwestern University found that the initiation of liver autophagy is a key link for exercise to bring systemic metabolic benefits.

Their research shows that exercise causes muscle to release a signal molecule called fibronectin 1(FN1), which reaches the liver through blood circulation and acts on α5β1 integrin on the surface of liver cells, thus triggering autophagy in the liver, thus improving metabolic health problems such as insulin sensitivity [2]. The article was recently published in the journal Cell Metabolism.

Autophagy abnormality has been considered to be related to many metabolic disorders in recent years. Previous studies have shown that exercise can induce autophagy in skeletal muscle of mice or humans through energy stress, oxidative stress and increase of intracellular Ca2+ level. In addition to these muscle tissues, many studies have shown that exercise can also activate autophagy in non-contractile muscle tissues such as liver, pancreas and adipose tissue, but the mechanism is still unclear [2].

Therefore, He Congcong and others deeply explored whether exercise can unlock the autophagy pathway of the liver and its role in systemic metabolic health.

First of all, they constructed a group of mouse models (ATG7Δliver) in which autophagy gene ATG7 was specifically down-expressed, so as to inhibit autophagy in liver cells.

Under the regular diet, the metabolic indexes of these mice are similar to those of wild-type mice. However, in the case of high-fat diet and running for 50 minutes every day, after 7 weeks, although the weight of the two groups of mice was similar, unlike wild-type mice, exercise did not save the glucose tolerance and insulin sensitivity of ATG7Δliver mice under high-fat diet.

These indicate that the improvement of metabolic health by exercise depends on autophagy of liver cells.

Exercise can’t save at G7 δ liver mice.

The results of in vitro experiments show that plasma and serum of wild-type mice can activate hepatocyte autophagy when they are in exercise, but plasma or serum at rest can not. In other words, there is a switch in the blood to turn on the autophagy pathway of the liver.

After protein’s proteomic analysis of the blood of mice, the researchers found that the level of fibronectin (FN1), an extracellular matrix protein that can be expressed by many types of cells, increased significantly in the blood of wild-type mice after exercise.

In addition, the experimental results in vitro showed that adding activator of AMPK, a cell energy sensor, to the culture medium could induce muscle cells to secrete FN1, but could not induce liver cells to secrete FN1. This suggests that the level of FN1 in blood is regulated by AMPK, and exercise may activate AMPK in muscle.

In the exercise state (when AMPK is activated), the extra FN1 comes from muscle cells, not liver cells.

In order to further study the role of muscle-derived FN1 in exercise, researchers specifically depleted FN1 (FN1(FN1Δmuscle) in mice muscles.

The results showed that the level of FN1 in the blood circulation of FN1Δmuscle mice did not increase after wheel running. Compared with wild-type mice, these mice did not get the improvement of systemic insulin sensitivity caused by exercise.

Specifically, the exhaustion of muscle-specific FN1 in mice did not affect its exercise-induced muscle autophagy, muscle morphology and exercise ability, and at the same time, the improvement of exercise-induced insulin signal transduction (activation of Akt regulatory factors) could be observed in its muscles. However, in this group of mice, the exercise-induced liver autophagy pathway was not activated, and no improvement in exercise-induced insulin signal transduction was observed in the liver.

These indicate that FN1 released by muscle is very important for the initiation of liver autophagy during exercise.

The depletion of FN1 in muscle affects liver autophagy.

From the mechanism point of view, during exercise, muscles secrete FN1, which leads to the increase of FN1 level in blood circulation. FN1 binds and interacts with α5β1 integrin in liver, activating IKK-JNK1-BECN1 signal pathway in liver cells, thus starting liver autophagy, promoting liver autophagy and reducing liver fat accumulation.

If the expression of α5β1 integrin in the liver of mice is inhibited, the weight, glucose tolerance and insulin sensitivity of mice can not be improved after high-fat diet and exercise, which proves the importance of α5β1 integrin -IKK-JNK1 pathway for the benefit of exercise-induced metabolism.

Overall, this study completed by He Congcong’s team shows that liver autophagy plays a key role in exercise-induced metabolic benefits, and reveals its mechanism. In addition, this study also shows that the metabolism of non-contractile muscle tissues such as liver can also be regulated by muscles.

　　Where have you planted grass recently? With the internet deeply embedded in people’s daily lives, social networks have become the main position for the spread of cultural tourism projects. Zibo BBQ, Tianshui Mala Tang, Guizhou "Village Supermarket", Chaoshan singing and dancing … … Relying on the fission spread of social networks, a number of phenomenal IP’s of cultural tourism have sprung up and gained popularity, which has driven the explosive growth of cultural tourism industry and promoted the local brand and image. Many places are also eyeing the new opportunities brought by social network communication, starting the "rocking people" mode and striving to become the next destination in online celebrity.

　　Shandong Zibo barbecue

　　"The fragrance of wine is also afraid of the depth of the alley", and the ingenious fancy propaganda has generated different traffic passwords, which has enabled many natural landscapes and cultural heritages of "bred in an inner chamber, with no one knowing her" to spread in a "broken circle". However, in some places, in the process of online marketing, there have also been practices that are divorced from reality, so that tourists come on impulse and return disappointed. For example, some scenic spots rely on "violent retouching" and AI synthetic videos to publish propaganda content that is inconsistent with the actual landscape; Some literary travel performances are over-exaggerated, full of vulgar, kitsch and vulgar pictures; Even the heads of cultural tourism departments in some places followed suit, ignoring the actual development of local cultural tourism, and the performance became self-entertainment. If everything goes too far, promoting "excessive force" will not only make the audience feel tired and resistant, but also raise the expectations of tourists too much and create the impression that "the goods are not right". Internet comment is a "double-edged sword". If it is divorced from reality and over-hyped, the higher it is blown, the worse it will fall.

　　Tourists in Jingxi, Guangxi are sightseeing in the scenic spot.

　　Rich tourism resources and profound cultural heritage are the basis and foundation for local development of cultural tourism. It is inseparable from sincere attitude and solid service to catch the "sky-splashing traffic". The development of cultural tourism is a comprehensive experience. Although some places are endowed with natural resources, due to insufficient investment in the early stage, weak infrastructure and reception capacity, they cannot meet the diversified needs of tourists, and they lack the ability to deal with emergencies and respond to risks after the influx of huge traffic. While actively operating social network accounts, relevant places need to "keep fit" and cultivate "internal strength", improve the cultural tourism industry chain, and make overall plans to improve the hardware level and software quality.

　　Tourists enjoy the scenery in Suzhou scenic spot, Jiangsu Province

　　Creating a high-quality cultural travel IP lies in the accumulation of word of mouth. The cultural tourism industry is an important starting point for promoting consumption and expanding domestic demand. It needs to be clear that some scenic spots not only win traffic but also leave word of mouth because they persistently strengthen service quality supervision and create a tourist-friendly tourism environment. All in all, the propaganda of cultural tourism is innovative and grounded, so as to truly retain tourists and win a good reputation. (Zhong Wang, special commentator of Yangguang. com)

CCTV News:According to the official news of the National Climate Center, in the autumn of 2023 (September to November), the national average temperature was 1.1℃ higher than normal, which was the warmest autumn since 1961. The precipitation is slightly more overall, but the spatial distribution is uneven. In autumn, there were nine regional rainstorm processes in China, among which the rainstorm process was particularly strong from September 3 to 13. Less typhoons are generated, more landings are made, and the impact is heavy; There are frequent cold air processes, of which two processes reached the cold wave level on November 6-7 and 23-25; Stage development of meteorological drought in the southeast of southwest China; The autumn rain in West China lasts for a long time and there is more precipitation. Northeast China and eastern Inner Mongolia have frequent rain and snow and thick snow. From the end of October to the beginning of November, a large range of haze and foggy weather appeared in parts of central, eastern and southwestern China.

　　I. National Weather and Climate Characteristics in Autumn of 2023

　　The national average temperature is the highest in the same period in history.

　　In the autumn of 2023 (September to November), the national average temperature was 11.3℃, which was 1.1℃ higher than the normal period and the highest in the same period since 1961. The temperature is 0.5-2℃ higher in most parts of the country, with 2-4℃ higher in northern and eastern Xinjiang. The average temperatures in Guizhou, Liaoning, Sichuan, Tianjin, Xinjiang, Yunnan and Zhejiang are all the highest in the same period since 1961, and Gansu, Henan and Shandong are the second highest.

　　During the season, the daily maximum temperature of 66 national meteorological stations in Dunhuang, Gansu (37.4℃, September 4th) and Guazhou (36.8℃, September 5th) exceeded or equaled the local historical extreme value in autumn. Extreme daily cooling events occurred at 36 stations in Northeast China, Hebei, Inner Mongolia, Shandong, Shaanxi and other places, and the daily cooling range of Wudalianchi in Heilongjiang (17℃, November 3) exceeded the historical extreme.

　　The overall precipitation is slightly higher and the spatial distribution is uneven.

　　In autumn, the national average precipitation is 126.8 mm, which is 5.3% more than the normal period (121.4 mm). The spatial distribution of precipitation is uneven. The precipitation in most parts of North China, the south of southwest China and western Sichuan, central and western Inner Mongolia, western and southeastern Xinjiang, western and southern Tibet is less than 20% to 80%, and the local precipitation is less than 80%. Central and northern central China and southeastern Shaanxi, northeastern Chongqing, most of Guangdong, southeastern Guangxi, eastern Qinghai and northern Xinjiang are 50% to 2 times more. The precipitation in Guangdong is the highest in the same period in history, and Qinghai is the second highest in history.

　　During the season, the daily precipitation of 56 national weather stations in China exceeded the local historical extreme in autumn, and the daily precipitation of 10 stations, including Fuzhou, Fujian (395.9 mm, September 6th) and Panyu, Guangdong (361.9 mm, September 8th), exceeded the historical record.

　　Second, the main weather and climate events in autumn

　　Nine regional rainstorm processes occurred.

　　In autumn, there were nine regional rainstorm processes in China, among which the rainstorm process from September 3 to 13 was particularly strong.

　　From September 3 to 13, affected by "Anemone" and its residual circulation, heavy rains occurred in Jiangnan and South China, with large accumulated rainfall and daily precipitation in many places breaking historical extremes. The cumulative rainfall in eastern Fujian, southern Guangdong, eastern and southern Guangxi, eastern Hainan and Taiwan Province is 100-300mm, including 300-500mm in northeastern Fujian, southwestern Guangdong and eastern Guangxi, over 500mm in six counties (cities, districts) such as Changle, Yangchun and Bobai, Fujian, Fuzhou, Fujian (395.9mm) and Panyu, Guangdong (361.9mm).

　　Typhoon generation is less, landing is more, and the impact is heavier.

　　In autumn, four typhoons were generated in the Pacific Northwest and the South China Sea, which was significantly less than the normal period (11 typhoons), and all four typhoons landed in China, which was more than the normal period (2 typhoons).

　　No.9 typhoon "Sura" landed on the southern coast of Zhuhai, Guangdong Province on September 2, with a small scale but strong intensity, and the super typhoon level lasted for a long time. Typhoon No.11 "Anemone" landed on the southeast coast of China three times from September 3 to 5. "Sura" and "Anemone" have successively affected South China, resulting in overlapping risks of rain and waterlogging. Many small and medium-sized rivers have experienced floods exceeding the police, and many places in Guangdong have experienced waterlogging, landslides, road interruptions and other dangers. Typhoon No.14 "Little Dog" landed at Eguanbi, Pingtung County, Taiwan Province on October 5, which was the third strongest typhoon landing in October since 1949, with a long impact time and a large accumulated rainfall. From October 5 to 11, the cumulative precipitation in six counties (cities, districts) in Guangdong Province was the third highest in the same period since 1961. Typhoon No.16 "Sanba" landed in Hainan and Guangdong three times from October 19 to 20, and the precipitation in eight national weather stations in Guangxi and Guangdong Province exceeded the extreme value in October.

　　There are 10 cold air processes affecting China, and the number of processes in November is obviously higher.

　　In autumn, a total of 10 cold air processes affected China, and the number was close to the same period of the year. 6 times occurred in November, 1.7 times more than normal. Among them, two processes from November 6 to 7 and from November 23 to 25 reached the cold wave level.

　　From November 3 to 7, cold air and cold wave processes successively affected China. Except for the eastern part of southwest China, southern China and southern Jiangnan, the temperature in most parts of the country dropped by 8-16℃, and the temperature in eastern North China and central Shandong, central and northeastern Inner Mongolia, northwestern Heilongjiang and central and southern Liaoning dropped by more than 16℃. The process of cold air and cold wave causes a wide range of gale cooling and rain and snow weather, which has a great impact on agriculture and animal husbandry production, transportation, energy supply, urban operation, human health and residents’ life.

　　Stage development of meteorological drought in southeast of southwest China

　　In autumn, due to the influence of high temperature and less precipitation, meteorological drought in Yunnan, Guizhou, Sichuan and Chongqing developed in stages and eased in the middle and late October. Since November, the meteorological drought in the southeast of southwest China has developed again. Up to now, there are moderate to severe meteorological droughts in eastern Yunnan, western and southern Guizhou.

　　The autumn rain in West China started early and ended late, with a long duration and more precipitation.

　　In 2023, the autumn rain in West China began on August 23rd, 10 days earlier than normal, and ended on November 16th, 13 days later than normal. The autumn rain period is 85 days, which is 24 days longer than normal. From August 23rd to November 16th, the average rainfall in West China was 287mm, 44.6% more than normal. The rainy weather from September to early October is not conducive to autumn harvest, stubble preparation and rape sowing and seedling raising in some parts of West China, but precipitation is beneficial to farmland moisture increase and agricultural water storage.

　　Northeast China and eastern Inner Mongolia have frequent rain and snow, with deep snow.

　　In November, there was frequent rain and snow in Northeast China and eastern Inner Mongolia, and the number of snowfall days was generally more than normal, with 5 to 10 days more in eastern Heilongjiang, central and southern Jilin, northwestern Liaoning and parts of northeastern Inner Mongolia. The cumulative precipitation in Heilongjiang and Jilin are the highest in the same period since 1961, and Liaoning is the second highest. The number of days above heavy snow in Heilongjiang and Jilin is the highest in the same period since 1961. The maximum snow depth in most parts of Heilongjiang, western Jilin and northwestern Liaoning is 5 to 20 cm, including 20 to 40 cm in eastern Heilongjiang and over 40 cm locally. Deep snow and ice accumulation have a great impact on transportation and energy security.

　　Three strong convective weather processes affected China, and Jiangsu was hit by a strong tornado.

　　In autumn, there were three severe convective weather processes in China, which were on September 17-18, September 19-20 and November 5-6. A total of 159 counties in 19 provinces have been affected by wind and hail disasters. On September 19th, Suqian City and Yancheng City, Jiangsu Province were hit by tornadoes of magnitude EF2 and EF3, respectively, which were seriously affected.

　　From the end of October to the beginning of November, a large range of haze and foggy weather appeared in parts of the east and southwest.

　　From October 28th to November 2nd, haze appeared in Beijing, Tianjin, Hebei, eastern Henan, western Shandong, eastern Hubei, northern Anhui, southern Heilongjiang, central Jilin and other places, and severe haze appeared in parts of Beijing, Tianjin and Hebei. Fog weather occurred in southeastern Liaoning, central Jiangsu, southern Anhui, central and northern Hunan, central and western Sichuan Basin, western Chongqing, northwestern Guangxi, central and northern Guizhou, central and southern Jiangxi, and northwestern Fujian. Haze and foggy weather cause reduced visibility and air pollution, which affects traffic and human health.

Luna

I always think that the Iranian diet is hard to describe with the word "beauty". The cooking method is single, the ingredients are limited, and the taste is not rich … It is too easy to "spit" the Iranian diet. However, the history of more than 3,000 years, the location at the turn of Asia and Europe, and the arid environment have all brought unique personality to the Iranian diet. It’s more like an adventure on the tip of the tongue. The sense of taste has shuttled through the Silk Road in Wan Li for thousands of years. In the end, I can’t simply evaluate it with delicious or unpalatable food, but I can say that diet has become an important way to understand Iran.

Ramadan survival

Because I arrived in Ramadan, my foraging experience in Iran was really not good. Most restaurants are closed, and there is almost no food for a whole day. But from the few small restaurants that are still open, I can get a glimpse of the most common and common diet in Iran.

crusty

I stood on the street with a high temperature of more than 40 degrees and gathered my headscarf. The scorching sun made me a little dizzy. There are almost no pedestrians on the streets of Isfahan, and all the shops are closed during Ramadan, except one: the shopkeeper hiding in the shadow is guarding a bag of neatly stacked cakes.

Ravensh All the pictures in this article were taken by Luna.

Lavash is an unfermented pancake, which is made of water and flour. The production method is described as "like a printed newspaper" in the documentary "Flavor Man". In fact, I think it tastes like chewing old newspapers, dry, tough and tasteless. But it is one of the daily staple foods in the Middle East, including Iran, and the surrounding Caucasus and Central Asia. Ravensh can be guaranteed for up to 6 months. Imagine the merchants in ancient Persia crossing the snow-capped mountains, Gobi desert and desert in Eurasia with camel teams. This kind of portable and full-bodied cake is really an excellent choice.

There are many kinds of Iranian cakes, and the word "Naan" comes from Persian. With the spread of Silk Road trade, fermented flour cakes have formed different forms in various places. For example, sangak in Iran is quite similar to Shizi steamed bread in Shaanxi.

Kebab

At dusk, the announcement sounded, announcing the end of the day when eating was forbidden and the time for dinner came. But even at night, there are not many restaurants open in Tabrizi, and there are even fewer choices on the menu, mainly kebab. This kind of meat dishes mostly use barbecue as a cooking method, which is one of the most popular main dishes in the Middle East, and it is eaten with rice or naan.

However, the food served startled me: a yellow stick was placed in the middle of the plate, with half a black baked tomato beside it, dotted with two green peppers. That yellow stick is my roast chicken, which is dry, hard and hard. As for tomatoes, I can’t bear to eat them. This dinner seems to laugh at me, who was baked in the hot Ramadan sun all day.

Mutton brain soup

Perhaps there are too few restaurants open in Ramadan. During my month in Iran, I have never eaten the rumored fresh and juicy Persian barbecue. The most important food for survival in Ramadan is the sheep brain soup that looks ferocious.

The hot night wind in Tehran blew a fragrance in front of me, and I found this small shop in a quiet side street along the fragrance. The sheep’s head is being stewed in a soup pot, with empty eyes looking straight at the diners, but the milky soup is bubbling, which makes me irresistible because of hunger and kebab.

　Mutton Soup

The mutton soup is rich, with a little spice and sweetness, which just neutralizes the fishy smell of mutton. I quickly drank a bowl and then ate the mutton satisfactorily. Later, I discovered that this way of eating was wrong. On the second visit, the boss demonstrated the correct way of local dining: first, add salt, lemon juice and cinnamon powder to taste, and then break the naan into pieces and throw it into the soup-a bit like mutton buns in Xi ‘an, which is obviously the result of thousands of years of exchanges between the East and the West.

Bosi renjia

It was not until I stayed in a traditional hotel and ate local home cooking that my adventure with the tip of my tongue entered a slightly pleasant period. Iran’s diet depends largely on local products, and local home cooking can better reflect different tastes in different regions, and the enthusiasm of Persians will also add a lot of color to food.

Dizi

Many traditional mansions in Kashan, Shiraz and Yazd have been converted into hotels, continuing the ancient hospitality. These mansions usually have a history of more than 100 years. Ancient and beautiful houses surround the courtyard. Pomegranate trees are planted in front of the porch, and there is a pool of clear water in the middle of the courtyard, which occasionally brings coolness when the wind blows.

The temperature in Shiraz in the valley is lower than that in other cities on the edge of the desert. We guests lie on couches laid in the shade of the courtyard and enjoy black tea, dates, salty yogurt and dizi.

Dizi

Dizi is a kind of stew, named after the earthenware pot where the stew is held, which is very common in Iran. Stew chickpeas, potatoes, tomatoes and mutton together until they are soft and rotten. Before eating, mash all these ingredients with a pestle, and then scoop out the broken mud with a spoon or naan cake to eat. Ignoring the slightly disgusting process of mashing, I eat it as stewed mutton with potatoes. The meat is delicious and melts in the mouth, making it the best main course in Iran.

Hummus

Near Persepolis, the ruins of the ancient Persian capital, I first walked into a local family. Surrounded by deserts, the whole village is almost made of local materials and built of loess. The host greeted us at the door and walked into his small courtyard. A bright and soft carpet had been laid in the cool and pleasant room, and the hostess set lunch in the middle of the carpet with a smile.

Hummus and hummus soup

Of course, the staple food is Ravensh, and the main course is hummus and hummus soup. Chickpea originated in the Middle East, and was introduced to China from Persia in the Yuan Dynasty, and often appeared in the prescriptions of traditional Chinese medicine. Middle Eastern countries, including Iran, have always used chickpeas as ingredients. The mashed beans are paired with olive oil and mint leaves, and the taste is fresh and dense. Pepper, onion and sour cream are added to bean soup, which is a good way to supplement nutrition in the barren desert.

After dinner, the host family sent black tea. In the warm water vapor, the host sang a song on the tambourine. Although the lyrics were incomprehensible, the music was cheerful and melodious. At that moment, I seemed to have joined the caravan more than 1000 years ago. After a long journey, travelers from far away finally came to the dream Persian capital.

camel meat

Iranians, or "Persians" as they prefer to say, have been outstanding businessmen on the Eurasian continent since ancient times. Their camel team crosses the desert Gobi and communicates with things, so camel meat is also a very popular food in Yazd, on the edge of the desert.

In this ancient city built with loess bricks, there is a traditional hotel named "Silk Road" that provides camel meat with two cooking methods: roasting and stewing. The meat quality of camel is a little rough, even the stewed meat can’t reach the soft rotten degree of mutton, but the meat is purer and more rustic, and there is no fishy smell, which can satisfy meat lovers.

A little sweet and sour

In the last few days of my Iranian trip, the end of Ramadan has restored amazing vitality to all cities. The streets that were originally empty have become bustling, shops in Bazzarri have opened one after another, and fragrant spices and sweet dried fruits are full, and I have also ushered in the most delicious period of food.

Bazzarri’s dried fruits

Saffron and Berberis

Under the bright sun in Tehran, a long line outside Bazaar attracted my attention. People stood in the high temperature and talked eagerly. The procession extended from the street to the second floor of a small building. I leaned over and looked around. On the second floor, there was a lively restaurant, full of cheerful diners and full of sweet food. Like Iranians, I was hungry for almost a whole month, and I immediately joined the queue-I didn’t even know what to eat at that time.

Zereshk Polo Morg

An hour later, I ate the only food served in the restaurant: Zereshk Polo Morgh. It looks very good. The diced orange-red rice is crispy outside and tender inside, with ruby-colored Berberis and bright green happy nuts scattered on it, and a big chicken leg.

I took a bite. The rice was crispy on the outside and soft on the inside. The entrance was very sour, but the aftertaste was faintly sweet. It was very appetizing on a hot summer day. No wonder so many people lined up. The orange-red color of rice comes from Iran’s specialty saffron, and Berberis is added. Its sour taste and salty chicken legs make the whole dish interesting.

This is the most delicious meal I have ever eaten in Iran, but my traveling companion was bitten by acid.

cherry

The vehicle took us out of Gatzwin and headed for the colorful Elbers Mountains. As the altitude increased, the temperature gradually dropped, and green Woods began to appear in the originally barren valley. Iranians on the roadside are guarding boxes of bright red cherries, waiting for the buyers in the city to arrive.

cherry

When it comes to fruits in the Middle East, sweet dates and figs are often mentioned. They are made into dried fruits and exported in large quantities, which are world-famous. But don’t forget that Iran is also one of the origins of cherries. Cherry trees are everywhere in the valley from Tabrizi to Gatzwin, and ripe red cherries are hung on thick green branches, which is the most pleasant scenery in hot summer.

Because of its origin, Iranian cherries are extremely cheap. The best quality cherries are about the same size as the diameter of a dollar coin, and the fruit is full and round. When you take a bite, it immediately overflows with sweet and sour juice, and the price is only 6 yuan a catty. Think about the high price of cherries in China, and the sudden arrival of "freedom of cherries" makes me and my traveling companions very happy, and I can’t wait to finish my lifetime quota of cherries here.

ice cream

Before the trip, I was looking forward to eating ice cream every day in Iran. As the origin of saffron and pistachio, both flavors of ice cream are quite popular in Iran. So immediately after Ramadan, I rushed into the first ice drink shop I saw in Gatzwin.

The shopkeeper was in business with his young son, and when he saw me, he burst into a Persian warm smile. Language barrier, the owner simply opened the freezer for me to choose. A cold air rushed out and sprayed my face, and my mind was clear for a few minutes. I picked out the yellow and white ice cream that other guests were eating. The teenager carefully took out the humble little box and put it on the table, and handed me the plastic spoon. The white part is milky, the yellow part is pistachio, and the side is also stained with fine pistachio pieces.

Pistachio nuts ice cream

This small green dried fruit originated in Iran and Iran, which was the first country to cultivate pistachios artificially and now the largest producer in the world. The taste of ice cream is not rich, but it tastes a little tough. The dense milk flavor is sweet with pistachios. When I swallow it, it is like finding a clear spring in the hot sun at noon in the desert-my Iranian food adventure is finally complete.

　　1. Purchasing mode

　　The main procurement contents of the company include three categories: the first category is raw materials, mainly including ceramic blanks, cobalt blanks, titanium blanks, polyethylene and so on; The second category is energy power; The third category serves external processing, mainly including spraying, basic machining and sterilization. The company set up a purchasing department to take charge of the procurement of raw materials and outsourcing services, and formulated a perfect workflow to ensure the efficient operation of the business.

　　(1) Procurement process

　　The purchasing department of the company shall be responsible for making purchasing plans, preparing purchasing orders, transmitting purchasing information, signing purchasing contracts, checking raw and auxiliary materials and establishing purchasing records according to the purchasing needs of various departments.

　　In terms of finished products and raw materials, the company’s procurement process is mainly carried out by bidding. First, the purchasing department conducts pre-qualification and selects three or more qualified units or suppliers to invite bids. Then, the purchasing department and the person in charge of purchasing control the bidding process and select one or more successful bidders for cooperation. The procurement contract drawn up during cooperation should include the necessary clauses such as quality constraint, time constraint and liability for breach of contract. After the contract is approved by the company, sign a purchase contract and quality agreement with the supplier, and ask the supplier to issue relevant certification materials. After the goods arrive, the quality department will control the quality. For outsourcing manufacturers, the company strictly controls the quality of outsourcing products and services by establishing and strictly implementing the selection criteria of outsourcing manufacturers and regularly evaluating outsourcing manufacturers.

　　(2) Development and management of suppliers

　　① supplier access and evaluation mechanism

　　The selection mechanism of suppliers shall be implemented in accordance with the company’s bidding system. Suppliers must have business licenses, legal production and operation certificates, quality management system-related documents, performance and safety evaluation materials of purchased goods, self-inspection reports of enterprises or effective inspection reports issued by qualified inspection institutions. Subsequently, the purchasing department took the lead in organizing the production department, R&D department and quality department to jointly invite tenders, and the suppliers who passed the evaluation were included in the List of Qualified Suppliers, which took effect after being approved by the management of the company.

　　② Quality control measures for suppliers’ supply.

　　The company agreed on matters related to quality compensation in the contract and signed a Quality Agreement with the supplier, binding the quality responsibilities of both parties. If the product is unqualified due to the supplier’s reasons, the supplier shall compensate the buyer for the losses according to the agreement. The company conducts normalized quality communication with suppliers to find out the reasons for unqualified raw materials and ask suppliers to make improvements. After the supplier improvement is completed, the company will check the effectiveness of the improvement, and the company will terminate the cooperation relationship with the supplier who fails to improve as required. The company conducts regular on-site inspections or temporary spot checks on major suppliers, inspects the supplier’s production process, ex-factory inspection process, personnel and equipment and corresponding process records, and judges whether the supplier has quality management capabilities, thus ensuring the quality of supply.

　　③ Settlement mode and settlement cycle

　　The company checks with suppliers every month, and after checking with the system, sorts out different types of business payment documents, which are approved by department managers and company leaders and then transferred to financial personnel for review and remittance.

　　The company settles accounts according to the payment time agreed in the contract, and suppliers with long-term cooperation and a certain purchase amount have a certain credit line.

　　2. Production mode

　　The company mainly produces based on strategic planning, market demand and annual sales target. With the cooperation of relevant departments, the production department carries out the established production and processing tasks according to the production plan, ensuring the company’s annual supply capacity and ensuring a certain safety inventory.

　　The production department tracks the orders received by the sales department in real time, and makes a production plan according to the sales volume in previous years in combination with the company’s safety inventory standards. After the production plan is determined, the production department issues the production task list according to the planned progress, and then enters the specific production process. After picking materials, the production personnel gradually carry out machining, polishing, lettering, cleaning, aseptic treatment and other links, and finally complete the warehousing. The production department of the company strictly implements the system related to production safety. In addition, the company sends safety personnel to supervise and inspect its work, strictly implements rectification for violations of rules and disciplines, and strengthens on-site management and hidden danger investigation to ensure the elimination of hidden dangers and reduce safety accidents.

　　The company’s main production modes are as follows:

　　For products with many varieties and small and medium batches, the company adopts the unit production management mode. This model has the advantage of high efficiency of assembly line production, and can also adapt to the changes of product variety and quantity quickly. The unitized production management mode is mainly composed of two parts: production unit and management unit, in which the production unit takes products as the center, centralizes the layout of equipment with different functions according to the process flow, and creates hardware conditions for realizing continuous production flow; The management unit carries out a series of management optimization around the planning management, personnel management, material management, equipment management and quality management of the production unit, so as to shorten the product delivery cycle and improve the production efficiency on the premise of ensuring the product quality. Under the unitized production management mode, the equipment, personnel and materials are reasonably allocated, and the production mode of "one person and multiple processes" with the goal of "one flow" in the unit is conducive to shortening the processing time and production change time of products with many varieties and small and medium batches.

　　For products with few varieties and large output, the company adopts multi-product batch production mode. In this mode, most products are designed in standardized modules, and the parts are universal and standardized. Employees have a high degree of division of labor and high proficiency in single process operation; Metal die casting, precision casting, die forging, precision forging and other methods are widely used in the production of blanks, with high precision, small machining allowance and high material utilization rate; The production line mostly adopts special and efficient equipment and process equipment, and repeatedly produces one or several similar products. The production process is mechanized and the production cycle is short.

　　For products with individual special requirements, the company adopts customized production mode. Customized production is based on modular design and standardization of parts. According to the special needs of customers, combined with the application of new materials and flexible manufacturing, it carries out secondary development and reorganizes the product structure and manufacturing process. This model not only meets the demand of customization, but also helps to reduce development costs, improve production efficiency and shorten delivery cycle.

　　In addition, the company introduced automatic production equipment in some production links to further improve production efficiency. For example, the company introduced intelligent grinding and polishing automation equipment to grind and polish the femoral stem, ensuring the accuracy of repeated positioning, while the built-in service information system can monitor the feeding of the moving machinery, and the motion control technology can also optimize the performance of the machine.

　　In addition to the above-mentioned self-production mode, based on the existing production capacity and cost control, the company entrusts some production processes to outsourcing manufacturers with corresponding qualifications or conditions for production, mainly involving product spraying, sterilization, surgical tool processing and so on.

　　3. Sales model

　　During the reporting period, the promotion of the "two-vote system" policy has brought certain changes to the sales model of the company and enterprises in the same industry. Before the implementation of the "two-vote system" policy, most enterprises in the industry mainly used the distribution mode to realize the professional division of R&D, production and terminal sales, that is, the manufacturers of orthopedic medical devices focused on the R&D, production, filing, registration and marketing of various orthopedic implants and instruments and tools, and the professional dealers focused on cooperating with the manufacturers to complete the marketing, terminal channel construction, sales and distribution, follow-up service for end customers, and operation follow-up. After the implementation of the "two-vote system" policy, the traditional distribution model was challenged, and sales service providers began to assume the responsibilities of some traditional distributors. Medical device manufacturers, distributors/distributors and sales service providers participated in the product sales and supporting services.

　　The sales modes of the company’s main products include traditional distribution mode, two-vote distribution mode, distributor mode and direct sales mode. During the reporting period, the company’s sales model was mainly based on the traditional distribution model. With the implementation of the "two-vote system", in recent years, the income of the company’s two-vote distribution model and distributor model has increased year by year.

　　(1) the traditional distribution model

　　During the reporting period, the traditional distribution mode was the main sales mode of the company. The main criteria for the company to select a distributor are that the distributor has the qualification for operating orthopedic products stipulated by the state, and the past financial performance and legal compliance of the distributor need to be investigated by the company’s background and field investigation. Due to the different amount of hospital operations, the company has no uniform minimum absolute sales requirements for dealers, but for dealers in some areas, the company will implement a rebate policy when their sales reach a certain target. The company makes full use of the distributor’s sales network and geographical advantages, constantly tapping potential customers, enhancing the product marketing ability and expanding the market share of products. The dealer agreement period is usually one year and is renewed every year.

　　Under the traditional distribution mode, products are sold to terminal hospitals through traditional distributors. Distributors undertake the responsibilities of channel development and customer maintenance, and provide follow-up service and other technical services including preoperative consultation, cargo transportation and equipment disinfection to end customers. At the same time, the marketing team of the company assists distributors to jointly complete channel development and customer maintenance by providing some technical and professional support. The business process of the company’s traditional distribution model is as follows:

　　Under the traditional distribution mode, the company’s payment system is assessed according to two standards: credit period and credit limit, and the payment is required according to the standard that is given priority. At present, most dealers expire the credit line first. After the credit line expires, the company stops the delivery, and the company will deliver the goods after the dealer makes the payment.

　　During the reporting period, the traditional distribution mode of the company was buyout sales.

　　(2) Two-vote distribution mode

　　Under the two-vote distribution mode, products are sold to terminal hospitals through two-vote distributors. Among them, the two-vote distributor only undertakes the functions of channel development and customer maintenance with the assistance of the company, while the follow-up service and other technical services are undertaken by the sales service provider. The business process of the company’s two-vote distribution model is as follows:

　　(3) Distributor mode

　　Under the distributor mode, the company’s products are sold to terminal hospitals through distributors. In this mode, the distributor does not undertake the promotion service function, while the sales service provider undertakes the follow-up service and other technical services under the two-vote distribution mode, and also carries out channel development and customer maintenance with the assistance of the company. In the process of selecting a sales service provider, the company mainly considers the local end-user resources, past service experience, historical cooperation, service personnel’s ability and other factors. The business process of company distributor mode is as follows:

　　(4) Direct selling mode

　　During the reporting period, the company’s main direct selling customer terminals were major hospitals, and the company had long-term and stable cooperative relations with major direct selling terminal hospitals. In recent years, the company’s high-end products have been listed one after another, and the company has also carried out several direct sales of customization/assembly and standard joints in Beijing and other regions. Under the direct selling mode, the channel development, customer maintenance, follow-up service and other technical services of the company’s products are mainly completed by the company’s self-built marketing team. The price of the company’s products is confirmed according to the winning bid price or the internal filing price of the hospital. The business process of the company’s direct selling mode is as follows:

　　For overseas markets, the company may adopt distribution mode, ODM or OEM mode for sales according to the specific situation.

　　In addition, in order to further introduce magnesium alloy-related orthopedic implant products and expand the market of trauma implant products, the company entered into a cooperation and distribution agreement with SynteixAsiaPTE.LTD in August 2019 to obtain the marketing, promotion and sales rights of related products in China, and agreed to purchase certain minimum purchase quantities of contract products within five years. The contract is valid until December 31, 2024, but up to now, SynteixAsiaPTE.LTD has not obtained the medical device registration certificate of related products in China, so the contract has not been formally implemented.

　　4. R&D mode

　　The company’s R&D work is managed in strict accordance with the review principles of quality standards such as ISO13485 and ISO9001/GB/T19001. The specific process is as follows:

　　(1) Project demonstration and establishment

　　Based on the market research of the company’s R&D center, marketing department and other relevant departments, the company formulates the annual product development project plan. The R&D department formulates the annual product development/improvement work plan in combination with the annual product development project plan, market demand, product characteristics and technical requirements, and assigns the design and development project leader, who further clarifies the project name, project objectives, project significance, brief feasibility analysis and project planning time.

　　(2) Project planning and review

　　Combined with the actual situation of the scheme, the project leader further comprehensively evaluates the feasibility of the project, studies and supplements the product specifications, technical scheme, implementation schedule, main key technologies, risk analysis, etc., and arranges and summarizes the scheme and sends it to the department leaders for review. According to the specific needs, the project leader sets up a project team.

　　(3) Design, development and control

　　The project leader shall control the progress of product development/improvement projects as a whole, complete product development and product design change projects according to the requirements of quality system documents, and ensure the standardization of documents, processes and operations. The units of the design and development folder should at least include design and development project initiation, planning, input, output, verification, confirmation, conversion, etc.

　　In this stage, the project leader prepares the design and development input list, and then organizes relevant departments and personnel to review the design and development input.

　　(4) Verification review and registration inspection

　　The project team conducts mechanical and biomechanical tests according to the test plan, and verifies the products according to the relevant national standards, industry standards or company requirements.

　　After the company’s internal projects have passed the verification and review, the project team will prepare the relevant technical requirements documents for medical device products to be registered according to the specific requirements of relevant regulations, prepare samples for registration inspection, and submit them to the medical testing institutions recognized by National Medical Products Administration for registration inspection in time.

　　(5) Clinical evaluation and research

　　The project team and other relevant departments of the company jointly formulate the clinical evaluation plan, and determine whether the product needs clinical trials according to the product characteristics. For the products listed in the Catalogue of Medical Devices Exempted from Clinical Trials or evaluated by clinical trials and usage data of the same kind of medical devices, the company conducts comparison tests of the same products and compiles relevant clinical evaluation materials according to the relevant requirements of the Technical Guiding Principles for Clinical Evaluation of Medical Devices; For products requiring clinical trials, cooperate with CRO (Contract Research Organization) and other companies to take the lead in completing clinical trial plans and clinical trial summary reports.

　　(6) Application for submission and registration

　　The personnel in charge of registration in the project team shall compile relevant registration materials, register products and obtain approval.

　　(3) the industry situation

　　1. The development stage, basic characteristics and main technical threshold of the industry.

　　A. Industry development stage

　　Orthopedic implant medical devices is one of the important subdivisions of medical devices. Orthopedic implanted medical devices refer to the devices and materials that can be implanted into the human body through surgery to replace and support human bones or repair bones, joints, cartilage and other tissues, mainly including bone joint implants and joint implants, such as bone plates, bone screws, intramedullary nails, spinal fixation implants, artificial joints, etc., which belong to high-value medical consumables. Because they are implanted into the human body for a long time, they have a great impact on human life and health, and their value is usually high. According to the report on punctuation information, it is estimated that the market size of orthopedic implantable medical devices in China will be about 60.7 billion yuan in 2024, and the compound annual growth rate from 2019 to 2024 will be about 14.51%.

　　According to the different parts of use, orthopedic implanted medical devices can be divided into four categories: trauma, spine, joint and others. In China’s orthopedic implantable medical device market in 2019, the market segments of trauma, spine and joint accounted for 85.80% of the market; Among them, trauma is the largest market segment, accounting for 29.80%; Spine ranks second, accounting for 28.23%; Joints ranked third, accounting for 27.77%.

　　(1) Joint implanted medical devices

　　According to different parts, artificial joints can be divided into artificial hips, knees, shoulders, elbow joints and so on. Benefiting from the growing medical demand, the joint market has maintained a rapid growth. According to the punctuation information related reports, the market size of joint implanted devices in China in 2018 and 2019 is 7 billion yuan and 8.6 billion yuan respectively. It is estimated that the market size of joint implanted medical devices in China will be about 18.7 billion yuan in 2024, with an average annual compound growth rate of about 6.87% from 2019 to 2024. Due to the relatively high technical difficulty, complex production process and long service life of joint implants, the market for joint implants is mainly imported products, while domestic products account for a relatively low proportion.

　　(2) Spinal implants.

　　Benefiting from the increasing medical demand and the development of minimally invasive spine technology, the market scale of spinal implant medical devices in China is also growing gradually. According to the report on punctuation information, the market size of spine medical devices in China is 7.3 billion yuan and 8.7 billion yuan in 2018 and 2019 respectively. It is estimated that the market size of spine medical devices in China will be about 17.1 billion yuan in 2024, and the compound annual growth rate from 2019 to 2024 will be about 14.42%.

　　(3) Implanted medical devices for trauma.

　　The production technology of trauma products is mature and the market development is sufficient, which has maintained rapid growth in recent years. According to the report on punctuation information, the market size of trauma implanted devices in China was 7.7 billion yuan and 9.2 billion yuan in 2018 and 2019 respectively. It is estimated that the market size of trauma implanted medical devices in China will be about 17 billion yuan in 2024, and the compound annual growth rate from 2019 to 2024 will be about 13.15%.

　　(1) International medical device giants have more advantages in the market.

　　Although the overall gap between domestic medical device companies and international medical device giants is narrowing year by year, the problem of low overall level of medical device companies in China still needs to be solved. In the domestic and international markets, international medical giants still occupy the dominant position by virtue of strong technical strength, R&D ability, capital supply ability, brand influence and higher trust.

　　With the acceleration of import substitution, the market share of domestic enterprises has gradually increased. However, from the perspective of the market segmentation of orthopedic implants, the degree of localization of the joint market is still low, and at present, imported enterprises still occupy a dominant position.

　　(2) The industrial concentration of Class 2)III medical device enterprises has gradually increased.

　　Under the leadership of international medical device giants, domestic medical device companies, on the one hand, step up their technological catch-up and constantly narrow the gap with international giants, on the other hand, accept increasingly strict government supervision, while the fierce competition among companies continues to increase, and high-quality enterprises rise, making it difficult for some small and medium-sized enterprises to continue to operate and be eliminated. Generally speaking, the industry concentration of Class III medical device enterprises with high technology content is gradually increasing, and the trend of survival of the fittest, mergers and acquisitions is obvious. According to the Statistical Annual Report on Drug Supervision in National Medical Products Administration, by the end of November 2018, there were only 1,997 enterprises that could produce three types of products, which was 25.37% lower than the 2,676 enterprises at the end of 2013. With the backward small and medium-sized enterprises being gradually eliminated or merged, the concentration of China’s medical device industry will continue to rise, and the scale of enterprises will gradually expand. While broadening the product line, they will continue to consolidate and expand their own advantages.

　　(3) Domestic medical device companies are accelerating the process of import substitution.

　　Due to the lack of strict and unified standards for equipment industry and the influence of municipal/hospital bidding mode, the medical equipment industry has been in a state of low concentration. Therefore, for a long time, many medical device companies developed in specific areas by relying on their special geographical location and marketing network. However, with the improvement of domestic innovation ability and technical level, the scale of domestic medical device companies continues to expand, R&D investment continues to increase, and the quality and approval number of domestic devices have improved, which provides the possibility for domestic products to occupy more market share.

　　In addition, hospitals at all levels have certain pressure to control medical insurance fees, especially the basic medical insurance system for urban residents, whose fees are mostly divided by age, and the overall amount is small; In terms of reimbursement amount, the reimbursement amount for urban residents is limited. Therefore, the long-term pressure of medical insurance fee control is great, and the increase in the use of domestic devices is an inevitable trend, which also provides an opportunity for domestic companies to accelerate import substitution.

　　(4) The development history is short and there are few large-scale enterprises.

　　The development history of domestic medical high-value consumables industry is only more than 20 years. In the field of orthopedics, the domestic manufacturers of orthopedic medical devices have a certain production capacity, and their products can basically cover various types of orthopedic diseases, and they have made certain progress in the fields of joint reconstruction devices, trauma and fixation orthopedic medical devices, orthopedic surgical instruments and spinal fixation devices. However, most domestic manufacturers of orthopedic implant consumables are small in scale, and their core products and market dominance are limited.

　　At present, there are few manufacturers of orthopedic implant consumables in China. From the perspective of enterprise scale, China’s orthopedic industry is still in a relatively primary stage. At the same time, because there is still a gap with imported products in prosthesis materials, prosthesis shape design, accuracy of surgical positioning instruments, joint surface smoothness, and treatment of contact surface with bone, the products of domestic manufacturers mainly focus on trauma and spine products, and the share of state-owned manufacturers in the joint market is relatively low.

　　(5) The competition pattern is scattered, and the trend of industry integration is obvious.

　　Because most of the manufacturers of high-value medical consumables and orthopedic implants in China are small in scale, the industry competition pattern is relatively scattered. In recent years, major market participants have integrated through mergers and acquisitions. For example, in 2012, Johnson & Johnson acquired Synthes, a Swiss medical plastic equipment manufacturer, and later joined DePuy subsidiary to become Johnson & Johnson DepuySynthes；; Stryker acquired China Enterprise Chuangsheng Medical in 2013; Medtronic acquired Kang Hui Medical in 2012; Xerox has successively acquired American sports medicine product manufacturer ArthroCareCorp, orthopedic robot company BueBet, and the BST-CarGe cartilage repair business of Indian pharmaceutical company PiramaHeathcare. The trend of industry integration is obvious, which provides development opportunities for enterprises with considerable scale in the industry. According to the report on punctuation information, in 2019, the top five companies in China’s orthopedic implantable medical devices market were Johnson & Johnson, Medtronic, Jiemai, Stryker and Weigao Orthopedics, with market shares of 17.24%, 9.70%, 5.97%, 5.19% and 4.61% respectively, totaling 42.71%, and the industry concentration increased.

　　(6) The demand for high-end products is still expanding.

　　With the increase of national disposable income, the increase of the proportion of the elderly population, the change of medical concept and the expansion of medical insurance coverage, the demand for high-end orthopedic medical devices in China will maintain a high growth rate.

　　After years of market cultivation, patients’ acceptance of orthopedic implants has been continuously improved. In the future, investment and mergers and acquisitions in the field of high-end orthopedic medical devices will increase, and good market prospects and huge growth space will bring greater impetus to the development of enterprises.

　　C. Main technical thresholds

　　Medical devices are knowledge-intensive and technology-intensive industries with multidisciplinary integration, and because orthopedic medical devices are directly applied to the human body, the safety, effectiveness, accuracy and reliability of medical device products must be guaranteed, which means that medical device manufacturers must continuously improve their technical level through continuous research and statistical analysis of large-scale clinical data before they can develop products that guarantee quality and meet customer needs. New entrants to the industry often do not have this technical level, and the difficulty of entering the market is further increased.

　　2. Analysis of the industry position of the company and its changes.

　　Based on China’s huge population base and the trend of accelerating aging, China’s orthopedic market is huge and has considerable growth potential. International orthopedic giants have successively entered the China market through local mergers and acquisitions or investment in factories. The period of investment and factory building is longer than that of mergers and acquisitions. Most international orthopedic giants choose mergers and acquisitions to open the China market.

　　In recent years, with the support of national policies and the opportunity of domestic market expansion, domestic orthopedic medical science and technology companies have gradually developed and expanded. The main domestic listed companies in the same industry mainly include Aikang Medical, (), Weigao Orthopaedics, () and Sanyou Medical.

　　The company’s main products are joint implant consumables. Because the artificial joint prosthesis needs to form a permanent combination with human bone tissue and replace the original function of human body, the raw materials of artificial joint must have better compatibility with bone and advanced bone interface fixation technology, which has higher manufacturing threshold and technical difficulty. Therefore, artificial joint is an orthopedic subdivision field with high technology content, high added value and high entry threshold. Due to the limitation of domestic raw materials and technology, imported enterprises still occupy the absolute dominant position in the whole market segment.

　　According to the report on punctuation information, in 2017, 2018 and 2019, the market share of foreign-funded enterprises in the joint implant device market in China was 67.88%, 66.71% and 65.06% respectively. The market share of local enterprises is 32.12%, 33.29% and 34.94% respectively, and the proportion is increasing year by year. Among them, Chunli Medical occupied 8.96% of the market share of joint implanted medical devices in China in 2019, ranking second among all local enterprises and fourth among all joint prosthesis enterprises (including foreign enterprises) in China.

　　3. The development of new technologies, (), new formats and new models during the reporting period and the future development trend.

　　3D printing technology: The company has introduced a variety of 3D printing equipment with different process types, and the "research and development project of customized and personalized prosthesis series products" is also in progress.

　　The company’s 3D printing equipment mainly includes EBM (Electron Beam Melting) equipment, MJF (Multi-jet Melting) equipment, and powder metal 3D printing equipment. Among them, electron beam molten metal 3D printer can melt titanium alloy powder layer by layer by using electron beam in vacuum to generate dense parts, which can realize printing of porous materials. Chunli Medical has mastered the technology of using electron beam technology to produce bone trabecula and other products. Multi-jet melting 3D printer ensures the fineness of the edge of the printed object by spraying solvent and fine agent to the laid powder, and then carries out thermal radiation heating again, so that the powder is bonded according to the model interface and stacked layer by layer.

　　Chunli Medical has mastered the technology of using multi-jet melting 3D printer to produce guide plate, prosthesis die test and other instrument parts. In addition, Chunli Medical can use the powder-feeding metal 3D printer to coat the surface of the medical implant produced by the traditional technology with the metal powder of medical institutions. The metal powder is uniformly melted by laser irradiation, and then cooled into a solid to be combined with the metal surface, so as to realize the porous structure on the surface of the implant and promote bone growth. In recent years,

　　Chunli Medical is developing a product called Advanced Customization and Individualized Joint Prosthesis based on advanced technologies such as China National Bone Database and 3D Reconstruction. Compared with the existing customized joint prosthesis products, Chunli Medical can more effectively analyze and meet the specific needs of patients. In addition, in August, 2020, Chunli Medical was hired as the drafting unit of the Group Standardization Technical Committee of the 3D Printing Medical Device Professional Committee of China Medical Device Industry Association, and participated in the formulation of the group standards of 3D Printing Tantalum Metal Hip Prosthesis, 3D Printing Tantalum Metal Knee Prosthesis, 3D Printing Tantalum Metal Personalized Bone Defect Filler and 3D Printing Tantalum Metal Spinal Prosthesis, and was rated as the "Advanced Drafting Unit of the Group Standard of 3D Printing Medical Devices" by the professional committee.

　　New material technology: the company has carried out research and development on porous tantalum materials and magnesium materials. Compared with other prosthetic materials, porous tantalum has a unique bone-like structure, high porosity is conducive to bone growth, highly interconnected honeycomb structure provides extensive bone growth, high friction coefficient provides good initial stability of the implant, and its physical and mechanical properties are close to that of bone, so it is an ideal bone substitute material. The project "Development and Clinical Application of Porous Tantalum Bone Repair Materials and Implantable Products" declared by the company was approved by the Ministry of Science and Technology as the key project of the National Key R&D Plan "Research and Development of Biomedical Materials and Repair and Replacement of Tissues and Organs" in 2020. In the "Tantalum Technology Series Product R&D Project", the company plans to prepare porous tantalum by CVD (Chemical Vapor Deposition) and produce customized porous tantalum personalized bone defect filler. At present, it has obtained the acceptance notice of medical device registration application issued by National Medical Products Administration; In the "research and development project of dental series products", the company plans to design customized and individualized dental implant products with porous tantalum and complete the production conversion, which is currently in the design and inspection stage.

　　Biomedical magnesium alloy, as a representative of a new generation of biodegradable biomedical materials, has received extensive attention in recent years. At present, the listed products are mainly concentrated in foreign countries, and the indications are narrow. Compared with other medical metal materials, magnesium alloy has obvious advantages, such as good biodegradability, biological safety and biomechanical compatibility. The mechanical properties are similar to those of bone tissue, which can be degraded after being implanted in the body, avoiding the second operation to take out instruments, which is beneficial to revision surgery and reducing the economic burden and mental stress of patients. At present, the company’s "research and development of new biomedical materials series products" project is in the design stage.

　　To sum up, the company has made great efforts to research and develop related emerging technologies as innovative application directions, and the research and development work is progressing in an orderly manner.

　　(IV) Core technologies and R&D progress

　　1. Core technologies and their advanced features and changes during the reporting period.

　　The company has been focusing on the research and development, production and sales of implantable orthopedic medical devices. After years of research and development, the company has mastered a number of core technologies, including general upgrade technology and unique technology. Among them, universal upgrade technology is a technology based on universal technology or necessary technology, combined with Chinese bone characteristics, clinical needs and feedback, to optimize and upgrade product performance or technology; Unique technology is the core technology realized by the company based on R&D experience and future R&D planning through continuous research and development by relevant personnel. The core technologies mastered by the company include hip joint core technology, knee joint core technology, shoulder and elbow joint core technology, joint bone defect technology and spine core technology.

　　The details of the company’s main core technologies are as follows:

　　(1) Core technology of hip joint

　　The core technologies of hip joint mainly include low-friction joint interface technology, personalized biological femur technology, press-fit biological acetabulum technology and hip joint revision prosthesis filling technology.

　　Advanced technology of low-friction joint interface: ① Low-friction joint interface technology refers to the technology of improving the reliability and stability of ceramic parts and reducing the risk of broken ceramic parts by optimizing the processing technology of mortar cups and lining used with ceramics, thus prolonging the service life of artificial joints. ② During hip replacement, the straightness and roundness of products used with ceramic components should be strictly controlled, so as to avoid the uneven installation stress of ceramic components during clinical use and assembly, which will lead to the fragmentation of ceramic components. ③ At present, the machining tolerance of acetabular cup and polyethylene liner of most manufacturers in the market is difficult to meet the precision requirements of ceramic assembly. The machining accuracy of the straightness and roundness of the locking structure of ceramic liner and acetabular cup of our company is controlled at 0.007mm, and the machining error in the product processing process is controlled through special tooling and fixtures to ensure stability and consistency, prevent the ceramic components from being broken due to installation deformation during use, and at the same time, the more reliable locking mechanism enhances the anti-dropping ability of the prosthesis. ④ As far as ceramic materials are concerned, foreign giants and major domestic enterprises all adopt CeramTecGmbH bioceramic materials; As far as processing technology is concerned, the company is reliable in straightness and roundness, and there is no obvious gap between the company and the highest level in the industry.

　　Advance of personalized bio-femoral technology: ① Personalized bio-femoral technology refers to the technology of optimizing the neck length, eccentricity, proximal and distal dimensions of femoral prosthesis based on the basic data of Chinese physiology and anatomy, and cooperating with the tools corresponding to the press-fit relationship to obtain better medullary cavity matching, stability and anti-rotation performance. ② Based on the basic data of the bones around the hip joint in China collected in the "Chinese Bone Mapping Project", combined with this technology, a personalized biological femoral prosthesis suitable for the physiological anatomical structure of Chinese people is designed, which includes two neck shaft angles of 127 and 133, and each neck shaft angle is divided into two eccentric distances, with an interval of 0.5mm as a specification; There are 4 models and 100 specifications, and the size interval between adjacent specifications is small, which is highly matched with the patient’s medullary cavity. At the same time, the prosthesis has medial and lateral grooves designed based on the different load properties between the proximal bone and the prosthesis, which effectively improves the initial stability and anti-rotation performance of the prosthesis. The optimized lateral shoulder design of this kind of prosthesis can also be applied to minimally invasive surgery.

　　The advance of that press-fit biological acetabulum technology: ① the press-fit biological acetabulum technology refers to improve and optimizing the acetabulum design, so that the "equator" position of the acetabulum cup is stressed, the force transmission mode is optimized, and bet stability, component connection reliability, wear resistance and the like are obtained. ② The press-fit biological acetabular prosthesis designed in combination with this technology includes a acetabular cup and a acetabular lining. The outer surface of the acetabular cup is composed of a spherical cap, a hollow spherical table in the middle and a hollow spherical table at the bottom in turn, and its total height is lower than the bottom radius of the hollow spherical table at the bottom. When the prosthesis is installed, this design makes the "equator" position of the cup bear force, optimizes the transmission mode of force, and increases the initial and long-term stability of the prosthesis. The connection mode between the inner liner and the outer cup is taper press-fitting and slot locking, and the plum blossom anti-rotation design increases the connection reliability between the parts and enhances the stability between the two parts. And the service life and wear resistance of the prosthesis are improved. This technology can realize the universal matching between mortar cup and ceramic or polyethylene lining, which is convenient for clinical use.

　　Advanced filling technology of hip revision prosthesis: ① The filling technology of hip revision prosthesis refers to the technology of optimizing the filling design of acetabulum defect, making the shape and internal structure of the filler more suitable for the growth of cancellous bone and improving the compatibility between the filler and acetabulum. ② The prosthetic fillers for hip joint revision designed by this technology include crescent, L, round and other forms. The overall mesh structure design of the prosthesis forms a honeycomb structure with internal interconnection, and the pore size of its porous structure can reach 500 200 μ m; The diameter of porous structure of trabecular bone can reach 500 200 μ m; The porosity of trabecular bone porous structure is 50~80%, which can make cancellous bone grow into prosthesis quickly and firmly, and the elastic modulus of prosthesis is close to the physiological bone level of human body. After the implant of prosthesis filler using this technology, it conforms to the physiological stress distribution, reduces stress shielding to a greater extent and promotes bone growth; Moreover, the filler can be compatible with the total hip socket and used in combination, which is suitable for cases with acetabular defects of different degrees and meets the clinical needs of patients.

　　Advanced design technology of proximal humeral prosthesis: ① Anatomical humeral stem technology refers to the technology of improving the anti-rotation performance of prosthesis and prolonging the life of prosthesis by optimizing the shape of humeral stem of shoulder joint, the structural design and combination of osteotomy surface. ② During shoulder joint replacement, the fretting and rotation of the humeral stem can easily lead to osteolysis and the sinking of the humeral stem, which will affect the service life of the prosthesis. Combined with this technology, the design of the proximal ellipse of the shoulder joint prosthesis can effectively prevent the fretting caused by prosthesis implantation and avoid osteolysis. The disc design at the top of the prosthesis will cover the osteotomy surface after the prosthesis is implanted to prevent the prosthesis from sinking in the later stage; To some extent, it can prolong the service life of artificial joint, reduce the revision rate and relieve the pain of patients.

　　Advanced design technology of distal humerus prosthesis: ① Anatomical distal humerus technology refers to the technology of optimizing the shape and width of the lower humerus, reducing unnecessary bone cutting and ensuring postoperative bone integrity. ② In elbow replacement, when the humerus side is treated, the two sides of the treated humerus lower end are easy to break, which affects the stability of the prosthesis. The elbow humerus handle designed by combining this technology can effectively ensure the stability of the prosthesis after installation, and at the same time, reducing the width can adapt to more patients and improve the application range of the prosthesis.

　　(4) Repair technology of articular bone defect.

　　Joint bone defect repair technology mainly includes pelvic bone defect repair technology, knee joint bone defect repair technology and customized individualized bone defect repair technology.

　　Advanced pelvic bone defect repair technology: ① The pelvic bone defect repair technology is suitable for severe comminuted fracture of acetabulum, revision of acetabulum with a large number of bone defects, severe pelvic bone defects caused by pelvic tumors, etc. The pelvic prosthesis can better achieve limb preservation, and on this basis, it can realize the integration of prosthesis, bone and muscle in the state of severe pelvic bone defect. ② The acetabular prosthesis designed with this technology can be fused with acetabular bone in patients, and the acetabular prosthesis is more firmly fixed; The range of acetabular motion angle is large, which prevents acetabular prosthesis dislocation; The acetabular prosthesis can be assembled at will according to the conditions of different patients, which meets the needs of acetabular prosthesis of different patients; Can save limbs for patients and meet different osteotomy positions in hip and acetabular surgery, the acetabular prosthesis is consistent with the position and angle of the acetabulum in the original patient, and the function of the human body can be effectively and reliably reconstructed; The iliac buttress is provided with nail holes, so that the prosthesis can be firmly fixed with human bones, and the bone contact surface is of trabecular structure, which promotes human bones to grow into the pores, and further improves the firmness.

　　Advanced technology of knee joint bone defect repair: ① Through optimizing the product design, knee joint bone defect repair technology can restore the flexion and extension, internal and external rotation functions of knee joint under the condition of a large number of bone defects, and fully meet the activity needs of patients on the premise of limb preservation. ② The knee prosthesis designed with this technology is composed of femoral condyle, tibial plateau support, femoral marrow needle, tibial marrow needle, osteotomy section, etc. The convex articular surface of femur is in direct contact with the concave articular surface of tibia, which increases the contact surface of the joint and restores the flexion and extension and internal and external rotation functions of the knee joint. One end of the restraint is connected with the femur with a transverse shaft, and the other end of the restraint is directly inserted into the central hole of tibia to make the prosthesis achieve maximum stability. Bionic modeling is adopted to fully meet the requirements of patients’ activities on the premise of limb preservation, so that patients can recover as freely as before.

　　The advance of customized and individualized bone defect repair technology: ① customized and individualized bone defect repair technology can customize the joint prosthesis by using advanced digital processing technology to better meet the special needs of patients. ② The development of customized and individualized artificial joints makes up for the shortcomings in the field of artificial joints, so that patients with rare and difficult bone diseases can obtain unique personalized prostheses.

Screw holes are formed in the bone plates, and screws can be implanted into the screw holes in the bone plates to connect the bone plates with vertebral bodies. Locking rings are embedded in the screw holes in the bone plates. After the screws are implanted into the screw holes in the bone plates, the locking rings contact with the nut positions of the screws and expand to lock the screws in the screw holes in the bone plates. The original locking nail is changed into the current screw self-locking structure, which reduces the risk of screw falling off, and adds positioning holes on the bone plate to prevent the bone plate from shifting when implanted.

　　During the reporting period, none of the above core technologies has changed.

　　3. R&D investment table

　　Reasons for significant changes in total R&D investment compared with the previous year

　　Mainly because the company attaches importance to the research and development of new products, new technologies and new processes, and continues to increase the demonstration of R&D projects, the investment in R&D personnel salaries and other related expenses has increased; Based on the national joint collection situation, the company has increased the research and development of new pipelines such as joint surgery robot, sports medicine, PRP and oral cavity.

　　4. Research projects

　　5. R&D personnel

　　6. Other explanations

　　

　　Iii. Analysis of core competitiveness during the reporting period

　　(A) analysis of core competitiveness

　　During the reporting period, the company’s core competitiveness has not changed significantly.

　　1. Technical barriers to product design

　　① Implants with appropriate size, shape and design can significantly increase the success rate of orthopedic surgery, among which the main performance of joint products is to require its wear resistance and stability of bone interface, so as to prolong the service life of products. Among them, the improvement of wear performance is realized by the selection of friction materials and the design of joint construction, and the stability of bone interface is realized by surface treatment technology and the design of handle, cup and other parts. ② As one of the earliest enterprises in China to develop and produce advanced joint prosthesis products, based on clinical needs and doctors’ suggestions, the company has continuously improved its technical level through continuous research and statistical analysis of large-scale clinical data, and mastered mature experience in product design and development, from product market research, project establishment, drawing design and parametric programming, to product finite element analysis, mechanical test, biological or zoological verification, clinical trial, product functional test, and then to registration application and trial production.

　　2. Technical barriers to product processing

　　① The production and processing of orthopedic implanted medical devices involves many processes, such as blank forming, machining, surface treatment, laser marking, cleaning, sterilization and so on, which requires high quality and safety of products. ② The company has a relatively mature and perfect processing flow, with traditional materials-reducing processing equipment such as turning, milling, planing, grinding and drilling, and materials-increasing processing equipment such as metal printers and resin printers, so as to ensure that the processed products are qualified in all aspects and accurately control every link in the production process. ③ The company has mastered some new processing technologies. The mesh structure of 3D printing products can realize rapid and firm bone growth. The company has advanced 3D printing equipment and mastered more mature printing technology, which can print biological prostheses with excellent performance. In addition, the company has initially mastered the chemical vapor deposition (CVD) process, which can realize the production of some porous tantalum metal products.

　　3. Technical barriers to research and development of new materials

　　① Biomedical degradable magnesium and magnesium alloy products: Biomedical magnesium alloy, as a representative of a new generation of biodegradable biomedical materials, has received extensive attention in recent years. At present, the company’s research based on magnesium alloy is being carried out in an orderly manner. ② Porous tantalum: Compared with other prosthetic materials, porous tantalum metal products have a unique structure similar to bone, high porosity contributes to bone growth, highly interconnected honeycomb structure provides extensive bone growth, high friction coefficient provides good initial stability of implants, and its physical and mechanical properties are close to those of bones, so it is an ideal bone substitute material; At present, the company’s research based on porous tantalum is being carried out in an orderly manner. The project "Development and Clinical Application of Porous Tantalum Bone Repair Materials and Implantable Products" led by the company was approved by the Ministry of Science and Technology as the key project of the national key R&D plan "Biomedical Materials R&D and Tissue Organ Repair and Replacement" in 2020.

　　(II) Events that have seriously affected the core competitiveness of the company during the reporting period, impact analysis and countermeasures.

　　

　　Fourth, risk factors

　　(A) Not yet profitable risk

　　(2) Risk of sharp decline in performance or loss

　　(C) core competitiveness risks

　　Orthopedic implanted medical devices stay in the human body for a long time, which requires high safety and needs to conform to the human bone structure. On the one hand, the ideal orthopedic implant material needs to have good biological properties such as biocompatibility, bioactivity and corrosion resistance, on the other hand, it needs to have good mechanical properties such as fatigue strength, mechanical stability, friction and wear performance. In recent years, new materials such as PEEK, degradable magnesium alloy and bioceramics have also appeared in clinical applications. The company has made corresponding layout for the research and development of new materials such as porous tantalum, magnesium alloy and PEEK, but there is still a certain gap compared with foreign giants. In the process of R&D, on the one hand, the company may face risks such as deviation in its own R&D direction, lagging R&D progress, and unsatisfactory R&D results, which may lead to an increase in R&D costs and time investment or even the suspension or failure of R&D projects; On the other hand, if the company’s R&D fails to achieve the expected material results and turn them into products, or the new materials cannot be effectively industrialized due to factors such as production technology and production cost, or the new materials cannot be successfully recognized by customers and markets, the company’s early R&D investment may not bring the company income or enhance its competitive advantage as expected, thus adversely affecting the company’s ability to continue to operate.

　　(4) Operational risks

　　(A) the risk of changes in sales model

　　The sales modes of the company’s main products include traditional distribution mode, two-vote distribution mode, distributor mode and direct sales mode. During the reporting period, the company’s sales model was mainly traditional distribution model. With the continuous expansion of the promotion scope of policies such as "two-vote system" and "purchasing with quantity", the revenue proportion of the company’s traditional distribution model will decrease year by year in the future. If the company can’t adapt to the changes of sales model in time and enhance the transformation ability of sales model, it will face the risk of blocked sales channels and customer loss.

　　(B) Market competition intensifies risks

　　The company’s main products are implantable orthopedic medical devices, and its end customers are medical institutions. For a long time, most of the domestic market share has been occupied by international brands such as Johnson & Johnson, Medtronic and Stryker. In recent years, with the technical progress and policy support, the trend of localization substitution is obvious.

　　However, the market share of domestic brands is still small, and domestic brands are facing fierce competition. The company must improve its product innovation and R&D strength according to market changes and industry development trends, so as to maintain its competitive advantage and develop steadily in the rapidly changing market environment. If the company fails to accurately grasp the development trend of the industry or correctly respond to the sudden changes in market competition in the future, it will face the risk of declining market share and product prices brought about by intensified market competition.

　　(C) the risk of declining market demand for implantable orthopedic medical devices

　　In recent years, with the acceleration of social aging in China, the number of patients with orthopedic diseases has accelerated, and the market scale of implantable orthopedic medical devices has also increased. In this context, during the reporting period, the company’s sales model increased year by year and maintained a high growth rate. If the disease spectrum or treatment methods change in the future, the clinical demand for implantable orthopedic devices will decrease or the medical insurance budget will decrease, which will lead to the decline of the market model of the company’s main products, which may adversely affect the company’s operation.

　　(D) Risk of income growth decline or fluctuation

　　From 2018 to 2021, the company’s operating income increased rapidly year by year, maintaining a good upward trend. Affected by the epidemic in 2020-2021, the growth rate of the company’s operating income declined. In the future, the company may fail to effectively expand sales channels, increase market share or promote R&D projects due to changes in macroeconomic environment, repeated epidemics, intensified product market competition and poor internal management of the company. The above situation may lead to a decline in the growth rate of the company’s operating income or a certain degree of fluctuation.

　　In September, 2021, the state organized the Joint Procurement Office of High-value Medical Consumables to publicize the results of this national procurement with quantity, and the terminal prices of the products to be selected by Chunli Medical and other selected manufacturers all dropped significantly. It is expected that the price reduction pressure will be further transmitted to the distribution price after the implementation of the procurement with quantity in the future. If the increase in the company’s sales volume cannot make up for the decline in the distribution price, the company may experience a decline in revenue and profits.

　　(E) Risk of supplier dependence

　　From 2018 to 2021, the company’s largest supplier accounted for a relatively high proportion of the total procurement in the current period. The specific products purchased by the company from CeramTecGmbH are ceramic ball heads, ceramic linings, etc. During the reporting period, the company increased the promotion of high-end products such as ceramic joint prostheses. In view of the high stability requirements of ceramic joint prostheses, the company chose CeramTecGmbH as the qualified supplier of ceramic parts of the company, and did not purchase similar products from other suppliers, so there was some supplier dependence. If we can’t reach an agreement with CeramTecGmbH on commercial terms in the future, or because of natural disasters, international trade disputes and other force majeure factors, CeramTecGmbH can no longer provide ceramic ball heads and ceramic linings to the company, which will adversely affect the company’s production and operation.

　　(VI) Lease risks of production and business premises

　　During the reporting period, part of the real estate used by the company for production and operation was acquired through leasing. If the lease cannot be renewed normally upon expiration, the rent is greatly increased during the lease renewal, or the lessor breaches the contract during the lease process, it may have a certain adverse impact on the normal production or operating costs of the company.

　　(seven) the risk of core materials relying on a single overseas supplier.

　　During the reporting period, the ceramic ball heads and ceramic linings used in the company’s ceramic joint prosthesis products were purchased from CeramTecGmbH. CeramTecGmbH is an advanced supplier of ceramic materials headquartered in Germany. Mainstream joint manufacturers at home and abroad, including Johnson & Johnson, Xerox, Stryker, Jiemai Bangmei, Aikang Medical, Chunli Medical and Weigao Orthopaedics, all purchase ceramic materials from the company. Due to international political and other force majeure factors, the supply of imported raw materials may be delayed, limited or the price may be raised. If the company can’t get enough raw material supply in time, the normal production and operation of the company may be adversely affected. At the same time, affected by international trade disputes, there is a risk that the purchase price will increase due to the increase of tariffs.

　　(VIII) external processing Risk

　　During the reporting period, the company’s spraying, basic machining, sterilization, surface treatment and other processes were mainly produced by outsourcing. If the company fails to effectively implement the outsourcing management measures, it may bring certain risks to product quality and delivery time; At the same time, if the outsourcing manufacturers fail to provide products with good quality and quantity according to the agreement, or violate the agreement, the company’s technical and commercial secrets will be leaked, which will have an adverse impact on the company’s production and operation.

　　(9) Risks not included in the procurement catalogue with quantity

　　In May 2019, the eighth meeting of the Central Committee for Deep Reform deliberated and adopted the Reform Plan for Managing High-value Medical Consumables. In July of the same year, the General Office of the State Council issued the Reform Plan for Managing High-value Medical Consumables, proposing: "For high-value medical consumables with large clinical consumption, high purchase amount, mature clinical use and produced by many enterprises, we should explore centralized procurement according to categories, encourage medical institutions to jointly carry out quantity negotiation procurement, and actively explore cross-provincial alliance procurement. Many provinces across the country have successively carried out pilot procurement of high-value consumables. On November 20th, 2020, the National Medical Insurance Bureau’s Medical Price and Bidding Guidance Center issued the Notice on Developing the Fast Data Collection and Price Monitoring of the Second Batch of Centralized Procurement of High-value Medical Consumables. The products involved in the second batch of centralized procurement include the following categories: artificial hip joint, artificial knee joint, defibrillator, occluder, orthopedic materials and stapler.

　　On April 1st, 2021, the Office of Joint Procurement of High-value Medical Consumables organized by the State issued the Notice on Information Collection of Some Orthopedic High-value Medical Consumables. On the basis of collecting the purchasing data of medical institutions in the early stage, in order to further understand the market situation of orthopedic high-value medical consumables, it is planned to carry out the information collection of orthopedic high-value medical consumables in batches. The first batch of high-value medical consumables such as artificial hip joint and artificial knee joint were collected.

　　On June 21st, 2021, the Office of Joint Procurement of High-value Consumables organized by the State issued the Announcement of National Centralized Procurement of Artificial Joints (No.1), and on August 23rd, 2021, it officially issued the Procurement Document of National Centralized Procurement of Artificial Joints, giving a comprehensive explanation on the product categories, procurement rules and bidding rules of this centralized procurement. The company won the bid for group A of ceramic-ceramic hip joint product system, group B of ceramic-polyethylene hip joint product system and alloy-polyethylene hip joint product system, but failed to win the bid for initial total knee replacement. The company’s inventory is relatively high, and it failed to replace the artificial total knee joint product system for the first time in the national procurement bidding with quantity. If the company can’t take corresponding remedial measures, the market demand will drop rapidly, and the company’s related products will face the risk of unsalable sales that are not included in the procurement catalogue with quantity.

　　(ten) the spine business scale is small, and the risk of losing the bid in the procurement with quantity.

　　At present, many provinces in China have implemented the purchasing policy of joint products, and Anhui Province has also introduced the purchasing of spine products. In the future, more provinces may introduce the purchasing of spine products. The overall scale of the company’s spine business is small, which has a certain impact on the company’s spine products to participate in the procurement with quantity, and there are certain disadvantages in the bidding competition, so investors should pay attention to the related risks.

　　(eleven) the uncertainty risk in the process of import substitution.

　　Although the overall gap between domestic orthopedic implantable medical device companies and international orthopedic implantable medical device giants is narrowing year by year, in the domestic and international markets, international giants still occupy the dominant position with strong technical strength, research and development capabilities, capital supply capabilities, brand influence and higher trust. With the gradual advancement of import substitution trend, both sides are also in a state of coexistence of competition and cooperation. In the process of import substitution, there is a certain gap between the company and international giants in terms of business scale, product technology, production capacity and brand building, and they will face certain challenges. In the future, the company will have certain uncertain risks in the process of import substitution.

　　(V) Financial risks

　　(A) the risk of a large balance of accounts receivable

　　From 2018 to 2021, the company’s accounts receivable balance continued to grow. If major adverse changes occur in the operating conditions of major customers and industry settlement methods, it may lead to overdue accounts receivable, bad debts or further extension of the accounts receivable recovery cycle, thus adversely affecting the company’s sustainable profitability.

　　(VI) Industry risks

　　The company is mainly engaged in the research and development, production and sales of implantable orthopedic medical devices, and its medical device industry must be fully supervised and managed by the National Development and Reform Commission, National Health Commission, National Medical Products Administration and other competent departments. Domestic enterprises engaged in research and development, manufacturing, management and use of medical devices should follow the regulations of medical device product classification management system, medical device product registration system, medical device production enterprise filing or licensing system, medical device management enterprise filing or licensing system, medical device management quality management standard, etc. The export sales of medical device products are also affected by the relevant policies of importing countries.

　　In recent years, policy changes at home and abroad have also caused multiple policy risks to the company, including:

　　(A) "quantity procurement" brought about by the risk of product terminal price decline

　　In July 2019, the General Office of the State Council issued the Notice on Printing and Distributing the Reform Plan for the Management of High-value Medical Consumables, exploring "procurement with quantity" in the field of high-value medical consumables. Up to now, Anhui, Zhejiang, Jiangsu, Fujian, Shandong and other provinces have issued and implemented the policy plan of "procurement with quantity" and implemented the bidding procedures involving joint products. Except for the company’s failure to win the bid for the "quantity procurement" of hip joints in Jiangsu Province in 2019, the "quantity procurement" of other provinces and related joint products won the bid. According to the current situation of winning the bid, the winning bid price of related products has mostly decreased to a certain extent compared with the price before "purchasing with quantity", which further led to a certain degree of decline in the ex-factory price of the company in some provinces.

　　In June, 2021, the National Joint Procurement Office of High-value Consumables issued the Announcement of National Centralized Procurement of Artificial Joints, Announcement of National Centralized Procurement of Artificial Joints (No.1), and in August, 2021, it officially issued the Procurement Document of National Centralized Procurement of Artificial Joints, and carried out the bidding work of national procurement of initial total hip replacement and initial total knee replacement. September 2021

　　In June, the state organized the Joint Procurement Office of High-value Medical Consumables to publicize the results of this national procurement with quantity. According to the public information, the average price of the hip joint terminal to be selected dropped by 80%, and the average price of the knee joint terminal dropped by 84%. The company successfully won the bid for "Ceramic-Ceramic Hip Joint Product System", "Ceramic-Polyethylene Hip Joint Product System" and "Alloy-Polyethylene Hip Joint Product System" at a relatively high price, but the price was significantly lower than that before the "quantity purchase". The company’s "knee joint product system" failed to win the bid because of its high quotation. The decline in the price of hip joint terminal and the failure to win the bid for knee joint will be transmitted to dealers and companies, and the subsequent distribution price of the company will also be reduced. If the increase in sales volume cannot make up for the decline in distribution price, the company may experience a decline in revenue and profit. In addition, if the company’s distribution price is too high, squeezing the dealer’s profit will affect the dealer’s willingness to cooperate, or returning the goods due to the termination of the dealer’s business with the company and negotiation, it may have a certain impact on the company’s profitability.

　　(B) The risk of knee joint products failing to win the bid for national procurement with quantity.

　　On September 14th, 2021, the State organized the Joint Procurement Office of High-value Medical Consumables to publicize the selected results of the national procurement of artificial joints, and the company failed to win the bid in the "knee joint product system". In 2021, Beijing Bestar Biotechnology Co., Ltd. (hereinafter referred to as "Bestar") obtained the "Record Certificate for Entrusted Production of Medical Devices" issued by Beijing Drug Administration, allowing our company to produce Bestar’s knee prosthesis as the trustee. Bethesda’s knee joint prosthesis won the bid in this collective procurement, and our company obtained the power of attorney from Bethesda (No.:BSD21-09- China -01-265), which authorized our company to sell its knee joint products in People’s Republic of China (PRC). Through the cooperation with Bestar, our company reduced the decline in profitability caused by the failure of our knee joint products to win the bid.

　　(C) Risk of changes in domestic and foreign industrial policies

　　The company is a medical device manufacturer, and its domestic sales revenue is the main source of its main business income. The domestic business development is strictly supervised by National Medical Products Administration and other competent departments. In 2018, the National Health and Family Planning Commission and other six ministries and commissions jointly issued the Notice on Consolidating and Breaking the Achievements of Supplementing Medicine with Medicine and Deepening the Comprehensive Reform of Public Hospitals, further clarifying the implementation of the "two-vote system" for the purchase and sale of high-value medical consumables. With the change of the sales model brought about by the two-vote system, the company is faced with changes in operating conditions such as longer receivable payment cycle and increased sales expenses corresponding to unit sales revenue. If the company fails to formulate effective countermeasures in time according to the changes in the "two-vote system" policy, it may have an impact on the sales and operation of its products.

　　In addition, policies such as medical insurance reimbursement and centralized procurement have been introduced in China, and policies such as DRGs and "one-vote system" have been actively explored. In 2021, eight ministries and commissions, including the National Medical Insurance Bureau and the National Health and Wellness Commission, jointly formulated the "Pilot Program for Deepening the Reform of Medical Service Price", with the goal of exploring and forming replicable and scalable medical service price reform experience through three to five years of pilot. In addition, the company is also actively exploring foreign markets, and the development of overseas business is strictly supervised by the competent authorities of relevant countries and regions. For example, the new version of the medical device regulation MDR passed by the European Union in March 2017, at this stage, some matters in the new MDR regulations have not yet been clearly defined, and there are certain risks of policy uncertainty.

　　In the future, the importance attached to the medical device industry at home and abroad will be further enhanced, and relevant regulations and policies will be issued in the aspects of industry standards, bidding, centralized procurement and circulation system. If the company can’t keep up with the development of industrial policies, study the requirements of new policies in advance, do a good job in coping with the New Deal, and continue to carry out technological innovation and product upgrading, the company may face the risk of falling product market prices, which in turn will lead to a decline in gross profit margin, which will adversely affect the company’s future profitability. The company will pay close attention to the trend of centralized purchasing policy, continuously strengthen production and management, enhance the company’s product innovation ability and comprehensive strength, strengthen market promotion, consolidate existing markets, develop new markets, and strive to increase market share.

　　(VII) Macro-environmental risks

　　In the future, the company may fail to effectively expand sales channels, increase market share or promote R&D projects due to changes in macroeconomic environment, repeated epidemics and intensified competition in the product market. The above situation may lead to a decline in the growth rate of the company’s operating income or a certain degree of fluctuation.
