Comment on People’s Art: Taking Talents as the Basis and Injecting inexhaustible Power into Non-genetic Inheritance

  Recently, the 7th China Intangible Cultural Heritage Expo was held in Shandong. Male prostitute, Peking Opera Mask, Tai Ji Chuan, Guangshan Huagu Opera, Tang Sancai Burning Skills, Xuzhou Xiangbao, Miao Xiu and other representative non-legacy skills, new works and special performances from all over the country were exhibited. A total of 332 non-legacy inheritors and 284 non-legacy projects participated in the exhibition.

  At present, 42 non-legacy projects in China have been selected into UNESCO’s non-legacy list and roster, making it the country with the largest number of non-legacy projects in the world. Behind this achievement is the unknown efforts and efforts of non-genetic inheritors in previous dynasties. Intangible cultural heritage, as an important symbol of the historical and cultural achievements of the country and the nation, not only bears the unique national memory, but also survives in the people’s lives in the process of generation replacement, which is of great significance for building a socialist cultural power.

  China is rich in intangible cultural heritage resources. Up to now, there are more than 100,000 intangible cultural heritage projects at all levels. With the joint efforts of the whole society, many intangible cultural heritages have re-emerged with new vitality. However, compared with many traditional cultures and traditional skills that are facing the risk of cutting off their inheritance, how to protect and explore the intangible cultural heritages so that they can "survive" and "catch fire" is still the top priority of our intangible cultural development.

  The key to let the non-legacy "survive" and "fire up" is to work hard to train the inheritors. China’s intangible cultural heritage projects are all amazing to the world, and once the skills of ancestors appear age or technical fault, there is a risk of being lost. Faced with the stringent requirements of intangible cultural heritage achievements, only a handful of people can bear the title of "non-genetic inheritor" with excellent skills after big waves. And if you want to inherit and carry forward the glorious legacy, you can’t do it quickly. Undoubtedly, the process of learning non-legacy skills has to endure hardships and loneliness. It is often necessary to concentrate on studying for several years or even more than ten years, carefully carving day after day, and silently sticking to the initial intention and persistence of non-legacy. A few days ago, the General Offices of the General Office of the Central Committee of the CPC and the State Council issued the "14th Five-Year Plan for Cultural Development", which clearly stated that "strengthening the cultivation of non-genetic inheritors." It can be said that the key to strengthening the inheritance of intangible culture lies in people, and it is urgent and imperative to cultivate more non-genetic inheritors.

  Cultivating more non-genetic inheritors requires more policy support. At the government level, it is necessary to refine the relevant policies and give comprehensive guidance. Improve the record system of intangible cultural heritage investigation, grasp the overall situation, focus on representative projects, start with the identification and system of inheritors, explore the standards and methods of identification, and form policy support for the cultivation of non-genetic inheritors.

  At the social level, it is necessary to strengthen the education of non-legacy science, especially from dolls, and set up non-legacy education bases to make more children interested in non-legacy. In addition, it is necessary to carry out the communication activities of intangible cultural heritage in various ways, and plant the concept of "non-inheritance is great and glorious" in people’s hearts, so that young people engaged in the study of intangible cultural heritage can gain more understanding and respect from society and families.

  It is necessary to "fire up", but also to expand the market, to actively embrace new technologies and glow with new vitality. We see that with the organic combination of new technologies and intangible cultural heritage, the spread of intangible cultural heritage has completely broken through the geographical restrictions. With the help of new opening methods such as internet plus and VR, intangible cultural heritage IP has become fashionable among young people. For example, a martial arts game combined with Xijiang Qianhu Miao Village, the first Miao village in the world, and three representative non-genetic inheritors of Miao nationality, added Miao cultural elements to the plot, architecture and costumes, which made more young people interested in exploring non-heritage students. The essence of ancient culture from China also entered the homes of ordinary people and passed down imperceptibly in the digital age.

  Chinese excellent traditional culture is the root and soul of the Chinese nation, and intangible cultural heritage, as an indispensable part of it, should be passed down through generations while continuing its glory. It is believed that with the continuous expansion of the market, more talents will join the team of inheritors and the team of protecting intangible heritage, so that intangible heritage can be better integrated into the daily life of Chinese and inject new vitality into the protection and inheritance of intangible heritage.

Stem cells VS immune cells: the double guarantee of vitality

In the human body, there are two important cell groups: stem cells and immune cells, which each play an indispensable role and jointly safeguard our lives and health.

Stem cells: the "supplement" of the body

Stem cells are special cells with multi-directional differentiation and self-renewal ability. They are like "supplements" of the body, and can differentiate into other types of cells as needed, which makes them have great potential in medical research.

● Hematopoietic stem cells can differentiate into blood cells such as red blood cells, white blood cells and platelets, which is of great significance for the treatment of blood system diseases, such as leukemia and anemia.

Umbilical cord mesenchymal stem cells can differentiate into a variety of tissue cells, have immunomodulatory and anti-inflammatory effects, and can be used to treat various tissue injuries and diseases, such as myocardial infarction, arthritis and cirrhosis.

● Neural stem cells can differentiate into neurons, astrocytes and oligodendrocytes, which have potential application value in the treatment of nervous system diseases, such as Parkinson’s disease, Alzheimer’s disease and brain injury.

……

Immune cells: the body’s "guard"

Immune cells refer to cells directly involved in or related to immune response. They are like the "guards" of the body, which can identify and remove foreign pathogens. From the most common bacteria, viruses and fungi in daily life to abnormal cell cancer cells in the body, powerful immune cells will sound the alarm at the first time and start fighting to maintain the stability of the internal environment and protect human health.

What are the main cells?

T lymphocytes can directly destroy infected cells.

● B lymphocytes can quickly eliminate re-invading pathogens.

● NK cells can directly attack and destroy infected cells and abnormal cells.

Macrophages can swallow and digest pathogens and other foreign bodies.

……

What are the differences between stem cells and immune cells?

1. Different production times

Stem cells usually begin to be produced in the fetus.

Immune cells are usually produced after birth.

2. Different shapes

The shapes of stem cells are usually diverse, such as hematopoietic stem cells are round, oval and long, and neural stem cells are radial.

The shape of immune cells is more uniform, round or oval.

3. Different distribution

Stem cells are mainly distributed in bone marrow, fat, teeth, umbilical cord and placenta.

Immune cells are mainly distributed in tonsils, lymph nodes, thymus, bone marrow and other parts of the human body.

4. Different quantities

Generally speaking, the number of stem cells in the body is relatively small. A 30-year-old healthy person has about 1 billion stem cells in his body. Among them, umbilical cord and placenta have the most abundant stem cells.

The number of immune cells is very large, and the number of immune cells in healthy adults is between 40 trillion and 60 trillion. Among them, the number of white blood cells accounts for more than 95%.

5. Different sources of acquisition

Stem cells can be obtained from many sources, including blood, bone marrow, umbilical cord blood, fat, skin, dental pulp and nerves.

Immune cells are mainly obtained from blood.

6. Different functions

Stem cells have the ability of multi-directional differentiation and can differentiate into many cell types.

The main function of immune cells is to identify and eliminate pathogens in the body.

If the human body is regarded as a huge factory, then stem cells are like engineers. They continue to produce new cells and provide necessary nutrition and support for all parts of the body through continuous differentiation, so that our body can continue to operate.

Immune cells, on the other hand, are like cleaners of machines, always alert to and remove any potential threats, including foreign pathogens, harmful substances in the body and abnormal cells in the body. When the body is damaged or aged, they will also appear immediately and start the repair and cleaning work, thus maintaining the balance and stability of the body.

In a word, it is

Stem cells do addition and immune cells do subtraction!

7. Different clinical applications.

More than 20 stem cell products, such as umbilical cord blood hematopoietic stem cells, bone marrow mesenchymal stem cells and adipose-derived stem cells, have been approved for marketing in the world to treat graft-versus-host disease, degenerative arthritis, Crohn’s disease and refractory anal fistula. In China, hematopoietic stem cell transplantation has been widely used to treat hematological diseases such as leukemia, lymphoma and myeloma, while other types of stem cells are still in the clinical research stage.

Immune cell products such as T lymphocytes, DC cells and CAR-T cells have been widely used in the world, especially in cancer treatment, and immune cell therapy has become one of the emerging treatment methods. There are only two CAR-T cell products approved for marketing in China, which are mainly used to treat hematological tumors and solid tumors. But because of its high price, it has not been widely used at present.

Stem cells and immune cells are significantly different in function and characteristics, but they are both important guarantees for our vitality.

Through "cross-border cooperation", stem cells and immune cells can double the role of "regeneration+cleaning". In 2018, the paper "Two to Tango: Dialogue between Immunity and Stem Cells in Health and Disease" was published in Cell magazine, which showed that the combined therapy of stem cells and immune cells can maintain the homeostasis in the human body and has important application value in anti-aging. In addition, the "strong combination" of the two can also play an important role in brain injury, autoimmune diseases and so on.

With the continuous progress of science and technology, our research and application of stem cells and immune cells are also deepening. In the future, we are expected to make better use of stem cells and immune cells, providing unlimited possibilities for treating diseases and improving the quality of life.

At the age of 17, he owns nine national invention patents, and all his whimsy comes from life.

·

A new invention: thermal liquid sensor was tested and verified in Chentian laboratory.

  During the awarding ceremony of the 2017 Qiu Chengtong Science Prize, I talked with Professor Yao Qizhi, an academician of the Chinese Academy of Sciences, an academician of the American Academy of Sciences and a Turing Prize winner.

  On the eve of the Spring Festival, Li Chentian, a 17-year-old high school student from Zhuhai, went to the United States at the invitation of Tsinghua University to participate in the "Global Innovation Experience Camp" jointly organized by Tsinghua and Washington University. He won the best project award in this innovation challenge by virtue of the "active high-voltage power line deicing monitoring system" invented on the spot. Later, he flew back to Beijing, as a participant in the last ISEF (International Science and Engineering Grand Prix), and introduced his experience to the young people who were participating in the 2018 ISEF project selection and international exchange winter camp.

  He invented the fluorine-free electronic refrigerator at the age of 9, the solar intelligent outdoor manhole cover management system at the age of 12, and the programmable terminal and operating system at the age of 13. So far, he has nine national invention patents … What kind of "awesome person" is Li Chentian? Why have you achieved so much at such a young age? The all-media reporter of Guangzhou Daily takes you to know the young man who is praised by the outside world as "Edison" in China.

  At the age of 5, I designed light-controlled lanterns for myself.

  Last weekend, when the reporter saw Jerry Lee Tianshi, he wore an old school uniform and black-rimmed glasses, which was very low-key; He was a little shy when he didn’t talk, but when he started talking about his invention, Li Chentian hardly stopped for more than two hours, and he spoke as fast as a machine gun. When I met some professional terms, I was a little confused when I watched the reporter. He kept changing his body movements to explain it.

  Li Chentian’s family said that his whimsy began in childhood. My father said that he showed a strong interest in electricity when he was learning English in the early morning. Every time he was carried out by his mother and saw the neon lights flashing on the street, he would dance. "How can anyone be on the TV?" "How can a toy car automatically turn?" ….. Since I was two years old, I have often asked my parents who are all from liberal arts to be speechless.

  Because of her strong interest in electronic products, at the age of five, Chen Tian borrowed her cousin’s middle school physics textbook for self-study. On the Spring Festival that year, the family was going back to their hometown. Before leaving, they were worried that the red lanterns hanging on the balcony of Zhuhai’s home were left unattended in the morning. They had been on for more than ten days, which was both a waste of electricity and a fear of causing safety accidents. He sprouted the idea of designing a light-controlled switch. "It will automatically turn off the lights when there is sunshine during the day and turn on the lights at night when there is no sunshine." As a result, he removed a sensitive relay from a radio through two days of fiddling, and really made such a switch through transformation.

  However, in the eyes of Chen Tian, the first real invention was the "fluorine-free electronic refrigerator" he built when he was 9 years old. Later, he was out of control. At the age of 12, he invented the "solar intelligent outdoor manhole cover management system", and at the age of 13, he developed the "programmable cloud-and-thing terminal and operating system" … At the age of 12, he won the first prize in the Guangdong Youth Science and Technology Innovation Competition for six consecutive years and won the national first prize three times. At the end of last year, Chentian won the Science Award and the Silver Award in Computer Science in the 2017 Qiu Chengtong Middle School Science Award Global Finals with his paper "Universal Power Adaptation Protocol (UPP) and Its Implementation". From provincial and municipal competitions to going abroad to represent China teenagers in ISEF, Li Chentian has won more than 30 scientific and technological innovation competitions, and has successfully applied for 9 national invention patents.

  All whimsy comes from life.

  "There is no epiphany in science. I just invested enough time in invention and creation. I just started the accumulation of’ 10,000 hours’ earlier." Li Chentian said modestly that to make inventions, we must first have a strong interest and then invest a lot of time.

  Chen Tian said that you should be curious when making inventions and pay attention to everything that happens around you. All my whimsy comes from life. The idea of the project "Active High-voltage Power Line Deicing Monitoring System" when I participated in the Innovation Challenge in the United States originated from the ice disaster in 2008. He was deeply impressed by the embarrassing picture of manual mechanical deicing in the power sector on TV, so he always had an idea, "If the frozen wires can be deiced automatically, even the wires in the alpine zone can not be frozen!" Over the past few years, he has done a full technical demonstration for this project, and this global innovation experience camp just gave him such an opportunity. Chen Tian said, "Due to sufficient technology accumulation, the original prototype of this project took only two days, and finally won the highest award’ ‘Best Project Award’ in the participating projects."

  The topic he is working on, "Variable Temperature and Pressure Pump", was inspired by his parents taking him skiing in Harbin during the winter vacation in 2016. At that time, he saw a small vendor barbecuing with liquefied gas on the street, and the fire went out. As a result, he saw the small vendor cover the gas bottle with a towel, pour some boiling water on the towel, and the fire "sprayed" again. He said that when he saw this phenomenon, he was very excited and thought that this phenomenon might solve the problem of transporting low-viscosity liquids such as refrigerants that he had always wanted to solve. If the pressure in the pump chamber is changed by changing the temperature instead of moving parts such as piston, wouldn’t it be possible to manufacture a pump without moving parts?

  Parents support the "disruptive" behavior of disassembling and tampering with household appliances from an early age.

  Chen Tian said, "If I make small achievements, I would like to thank my parents for their tolerance and support." Since childhood, his parents never forced him to attend interest classes, and he was not required to be a schoolmaster. He said that he has never attended any cram school since he went to school. During the holiday, he either stayed at home to make inventions or participated in scientific and technological competitions and exchanges in various places.

  Parents also fully support the "disruptive" behavior of dismantling household appliances that they have shown since childhood. Just in the first grade of primary school, in order to study the temperature control switch, I dismantled a newly bought electric heating plate imported from Germany at home in the morning. At that time, the market price was more than 2,000 yuan. When he was 9 years old, he developed a fluorine-free electronic refrigerator. In order to buy a refrigerator, his parents took him to Beijing to find many shops, and finally spent three days scouring Zhongguancun for the desired products.

  In order to support his son’s innovation and invention, his father set up a "morning lab" for him at home. In this laboratory, the reporter saw a laser positioning machine, a small supercomputer with 72 cores, a multifunctional calibration measuring instrument with data stability of 2ppm, a multifunctional vector network analyzer and a very advanced mixed-signal oscilloscope.

  "Over the years, the equipment in this laboratory alone has invested more than one million yuan, not including thousands of old electronic products that he invents and buys every time and dismantles." Chen Tian’s father smiled and said, "If we only talk about the electronic laboratory, my laboratory may be the best in Zhuhai."

  However, apart from scientific and technological inventions, Chen Tian has no other hobbies. As long as he doesn’t go out to participate in scientific and technological competitions and exchanges in his spare time, he basically stays in this laboratory.

  Learning computer programming in the fifth grade of primary school is painful to cry.

  Li Chentian does not agree with the reputation of the outside world as a "genius boy". His parents have repeatedly stressed that their children have only shown strong interest in electrical appliances and circuits since childhood, and they are ordinary teenagers. "He is only willing to spend time on electronics," my father said seriously. "Since I was a child, I love to disassemble things. Others sell old household appliances at home, and my family often buys them back from outside."

  Chen Tian added that every design or invention is not always smooth sailing, and there are many failures. There are two or three thousand discarded circuit boards at home. And when learning theoretical knowledge, I once had the idea of giving up. With the deepening of scientific research, he had to learn computer programming for a project in the fifth grade of primary school. Most of the electronic components encountered before are concrete things, while computer assembly language is too abstract. For a child in the fifth grade of elementary school, it is like reading a gobbledygook at first. "If you don’t understand, you can’t learn!" Sometimes I read until late at night, and in the morning I said that I was so miserable that I cried and wanted to give up several times. Finally, with the encouragement of his father, he persisted, and it took him more than a month to write the first program-"digital clock". Looking at the success of the first string of code written by myself, Chentian jumped with excitement. "He was yelling, and then he ran downstairs from upstairs and kept shouting, Dad, I made it up." Dad recalled.

Is there only FSD left in Tesla?

This article comes from WeChat WeChat official account:Unfinished research (id: Weijin _ research), Author: unfinished research, title map from: vision china

First, Apple gave up electric cars, and then Tesla gave up Model 2. They have one thing in common, All in AI. Musk also announced a day that would make the China market feel special magic.On August 8th, we will officially release its Robotaxi.. Will this be the first time that a car without a steering wheel has appeared?

The market value of Tesla is equivalent to 1.5 Toyota or 6.5 BYD. It has always convinced the market that its high-end electric vehicles and brand premium, its innovative manufacturing technology can mass-produce family-oriented economical cars, and lead the electric vehicle industry to the end of Robotaxi. Musk has always believed that Tesla can lead in these three aspects and can lead at its own pace.

But,Its market value has dropped by one-third this year, which is the worst performance among the seven technology giants.It must be that some in the market no longer believe the story told by Musk.

From the time point of view, Apple gave up building a car, and Tesla decided to give up Model 2, both at the end of February. It was this month that BYD put forward the slogan of "electricity is lower than oil", and then launched a new model with a price below $10,000.

At the end of March, Tesla began to let its 1.7 million car owners in North America try FSD software for free for one month. This time, Musk said that FSD v12.3.3 is a driver supervision version.(Supervised)It is no longer a beta.(Beta). Tesla upgraded the driving experience in the urban street environment through an end-to-end, fully visual model.

However, both technically and in terms of supervision,FSD is far from its literal meaning of "fully automatic driving", that is, driving at L4 and above.Although Tesla has more GPUs, Google’s Waymo and China’s competitors have ways to catch up with it.

Musk has a plan to mass-produce cheap models with an annual output of 20 million by 2030. He proposed to produce Model 2 in a super factory in Texas or Berlin, and even decided to build a bigger super factory in Mexico.

However, with the rapid growth of electric vehicles in China, Musk has gradually realized that,You can’t win by competing with your competitors in China on the price of cars.Tesla has been surpassed by BYD in terms of shipments and product diversity of new energy vehicles. By 2025, when it launches a $25,000 car, it will have no advantage in cost performance compared with the $10,000 car in China. American politicians also realize that 100% tariff may be needed to prevent China electric vehicles from entering the American market. That’s not enough. The White House and the Ministry of Commerce even began to look for reasons from the perspective of "security".

Tesla’s innovation in automobile manufacturing technology, such as Musk’s "non-traditional" production method, that is, using Lego bricks instead of assembling in an assembly line, can reduce the cost by 50%. But it can really be put into use, probably by the end of next year at the earliest. Some experts believe that the cost reduction may be only one third, andThere is great uncertainty about the actual production capacity of the new production line.

Tesla is adjusting its strategy. The destination of electric vehicles is intelligent driving. Since China has taken the lead in the field of electric vehicles, Tesla decided to change the car-Competing on the smart driving track.According to the biography of Musk, it will produce FSD cars on the same small car production platform and enter the Robotaxi mode.

Probably this is what Musk said about Reuters. "(again)The reason for lying. This media, which was cursed by Musk and was "dying", exclusively exposed the news that Tesla was giving up the production of Model2.

Does this mean that Musk gave up the goal of mass manufacturing cheap cars? This is its long-term vision since 2006: start with high-end cars, enter the field of mass production of cheap family cars, and then realize automatic driving.

Until January of this year, Musk told investors that he would produce cheap models in a factory in Texas in the second half of 2025. At present, Tesla’s cheapest model Model 3 costs $39,000, and the cheap Volkswagen is priced at $25,000, which is called Model 2. But China is introducing electric cars with a price of $10,000 or less. Obviously, even with a 100% tariff, it is difficult to stop the export of China cars to the United States.

Another reason is thatThe demand for electric vehicles in European and American markets is weakening.The growth in China is also slowing down. Since the beginning of 2022, Tesla’s capacity utilization rate has been in a downward trend, currently about 74%.

Trend of Tesla’s capacity utilization

Musk said that if Robotaxi cannot be realized, the value of Tesla will be zero. From 2024, this is not an exaggeration. If we only build electric cars, whether we use humanoid robots or non-traditional ways to build cars, these are not the threshold for China enterprises who are good at fast learning and rapid scale.

Musk must take three steps and two steps to launch an economical electric car.(Musk can still be called Model 2)Combined with FSD, it is possible to create truly different products.

  Core reading

  Chairman of the Supreme Leader pointed out, "‘ Belt and Road ’ What we are pursuing is the great profits of a hundred flowers, not the small profits that stand out from the crowd. " Over the past three years, China and countries along the route have exchanged needed goods, complemented each other’s advantages, shared opportunities and met challenges together. The mutually beneficial cooperative ties have become tighter and tighter, and a win-win partnership network is being woven. Against the background of insufficient momentum of world economic growth, the progress of economic cooperation under the "Belt and Road Initiative" is undoubtedly a rare bright color.

  Through the long yellow sand and the rolling blue waves, the blueprint nodes are turning into prosperous business centers, criss-crossing the ancient Eurasia. In the construction of the "Belt and Road", trade cooperation has achieved fruitful results. In 2016, the total trade volume between China and countries along the route was 953.6 billion US dollars, accounting for 25.7% of China’s trade volume with the world.

  It is worth mentioning that the new format economy represented by Internet companies is also actively laying out and going to sea side by side. Cross-border e-commerce has ushered in explosive growth and has become a new kinetic energy that cannot be ignored in driving trade development.

  Moscow, Russia

  90% of foreign postal parcels come from China.

  Behind the "Communist Youth League Station" of Moscow subway and between the two major passenger stations, there is a conspicuous orange board house. This is the first physical exhibition hall of Alibaba AliExpress Russia.

  Entering the exhibition hall, there are many products made in China, such as "free soldier" outdoor products and Xiaomi mobile phones, in the small space. Alena, a shop assistant, told the reporter that there are endless customers every day. After the manufacturer has reached an agreement with AliExpress, the products can be displayed here, and customers can log in to the online shop of AliExpress by scanning the QR code next to it. "The arrival time of the order has been controlled within 15 days. If it is from a local warehouse ‘ Mall ’ Delivery, then it takes up to 5 days. "

  According to the survey report of Russian Electronic Commerce Association and Russian Post Office, in 2016, the sales of online stores in China accounted for 52% of the total cross-border online trade in Russia, and 90% of foreign postal parcels in Russia came from China. According to the data of Therns Market Research Company in January 2017, the AliExpress platform has 22.2 million users.

  In addition to the increase in figures, AliExpress’s business has also undergone qualitative changes in two years. Today’s AliExpress website is exquisite and atmospheric, and the product name of the machine that makes consumers laugh and cry is no longer seen. It has become history to wait 60 days after placing an order to receive the goods. The "shopping mall" model with guaranteed quality, delivery speed and after-sales service has also become more and more perfect.

  In the spring of 2015, when the reporter interviewed Mark Zavadski, the business development director of AliExpress Russia and CIS, he was still a "army of one". One person was responsible for conducting business in Russia, and other personnel responsible for maintaining AliExpress Russian website were all in Hangzhou. Two years later, AliExpress has a large-scale company and two physical exhibition halls in Moscow.

  This spring, AliExpress is even more active in Russia. Alipay is about to land in China, appearing in duty-free shops and other places where tourists from are crowded. The goods of domestic sellers in 20 Russian big cities will soon be delivered the next day. There are also articles on the internet that teach people to use Taobao to rebate. Zavadski said: "E-commerce has the opportunity to replicate the glory of China in Russia, and may even achieve more achievements."

  At Zavadski’s insistence, Russian local manufacturers and sellers have joined AliExpress. At present, the transaction volume of local merchants has accounted for 5%, and this year, they will jointly launch fans’ clothing with Spartak Football Club.

  AliExpress has set up the "AliExpress Silk Road" group on VK, Russia’s largest social networking site, with the slogan "Bring the best goods like thousands of years ago". The rapid development of AliExpress has impacted and changed the local postal, financial and e-commerce systems.

  According to statistics, in 2016, the scale of cross-border e-commerce transactions in China reached 6.3 trillion yuan. In addition to traditional hot countries, goods from countries along the "Belt and Road" are gradually becoming popular targets of Chinese consumers. Among the users of AliExpress, the proportion of users in countries along the "Belt and Road" exceeded 45%.

  Because most small and medium-sized enterprises do not have the right to export, Dalong. com has built a "channel connection" to provide them with one-stop services such as payment recovery and export tax rebate. The financial person in charge of Dalong.com said: "Now the export orders of small and medium-sized enterprises have surged, and it is definitely impossible to use the traditional export tax rebate declaration method. Now we use the cross-border e-commerce online tax refund system of Chongqing State Taxation Bureau. We fill in the report online and automatically complete the comparison with the customs electronic port information. The whole process can be compressed to less than 7 days, and the cost is further reduced. "

  "In this way, we have solved the obstacles such as high cross-border procurement costs and excessive capital consumption of four types of overseas small and medium-sized offline retailers, online Internet providers, small and medium-sized wholesalers and professional buyers, and can realize the effective docking of China’s high-quality production capacity and overseas demand." Zhu Fuxing said.

  "Just give it a try for the first time, I didn’t expect the effect to be quite good. In the future, we will also serve the Dubai market in a targeted manner. " The relevant person in charge of Chongqing Yunzhong Technology Co., Ltd., which produces mobile power, introduced.

  At present, more than 30,000 small and medium-sized enterprises have begun to "go global" like Yunzhong Technology, among which more than 5,000 enterprises’ products have entered overseas markets. The LED lamps of an enterprise in Zhongshan, Guangdong Province have been sold in batches in Vietnam and other countries, and the sales volume has been rising. Inflators, wire brushes and adjustable wrenches produced in Qingdao, Shandong Province are well received in the UAE. Wedding products from Suzhou, Jiangsu, such as wedding gloves, embroidered skirts and flower baskets, are very popular in Canada, and some categories are sold out … …

  The "New Silk Road" was connected by the "net"

  Zhili Town, Wuxing District, Huzhou City, Zhejiang Province, this "China International Children’s Wear Capital" has nearly 10,000 children’s wear enterprises, and children’s wear sales have accounted for nearly half of the country.

  On the morning of May 8, when the reporter came to a children’s wear enterprise named Buyi Caoren in the town, I saw that the workers were rushing to produce a batch of new children’s wear, and the target customer was Italy thousands of miles away.

  "Through cross-border electronic commerce, we put children’s clothes along ‘ Belt and Road ’ Sold to Europe and Southeast Asia. " Ma Weizhong, the person in charge of the company, told the reporter that the cross-border e-commerce sales of Buyi Caoren are currently 1,500 US dollars per day, and the products are exported to more than 10 countries and regions.

  In 2015, Ma Weizhong began to think about how to open up international sales channels through the "cloud market" of e-commerce. However, he can speak less than 10 sentences of English, and he wants to understand that the international market is not only "speechless" but also "road-blind". "Later, I found that I don’t have to worry. The city has built a series of cross-border e-commerce service platforms, which provide a lot of valuable information and carry out relevant training according to the needs of enterprises." In October 2015, Buyi Caoren was launched on Amazon, and 200 sets of children’s clothes were exported in less than a week.

  "I referred to the supply and demand information of major platforms and analyzed ‘ Belt and Road ’ Designing products based on market conditions in different countries has achieved good results. " Ma Weizhong told reporters that the government departments also helped to take the lead in coordinating and solving the problem of cross-border settlement of enterprises. "Originally, the handling fee was higher through third-party enterprises, but now the channels of professional financial institutions have been opened, and the single settlement only charges 40 dollars regardless of the amount."

  In recent years, Wuxing District of Huzhou City has built the first county-level international e-commerce application platform in China — — Xing Wu international e-commerce application platform, and set up all the way import and export Co., Ltd., specializing in serving the export of small and medium-sized children’s wear enterprises. Jiao Chenkang, a staff member of the Wuxing District Bureau of Commerce, said that at present, there are more than 100 cross-border e-commerce enterprises cultivated through various platforms in the district, 80% of which are children’s wear enterprises, and the monthly export volume exceeds 10 million yuan.

  “‘ Belt and Road ’ Construction has opened up new ideas for enterprises in our traditional industries. " Ma Weizhong said that he hoped that in the future, the service platform could build a large database of cross-border e-commerce and launch more accurate support policies based on data analysis.

Gansu Mala Tang, initiated a request for continuous wheat

Original greedy YOU Chengdu

To say that the recent hot bite is delicious, Gansu Mala Tang is one.

On social platforms, many people share their experiences of going to Gansu to eat mala Tang. There are also people who deliberately go to Gansu to study and make mala Tang and prepare to open a Mala Tang shop in Chengdu. Just a short sentence of "returning from school and preparing for the store" has gained a lot of attention and expectation.

After a dish is cooked, it is filled with chili pepper red oil. Special local pepper, like free. Gansu mala Tang, which is strange to say, makes people wonder for no reason: what is this smell?

No, Xiao Du turned into a taster and found a shop in Chengdu to have a taste first.

● ● ●

Zhaolinji Northwest Mala Tang is located in Jiaochangba Middle Street.

For the first time, in order to avoid the crowd, I deliberately arrived at 1 pm, but I still underestimated the heat.

The shop was full of people inside and outside, and the boss told him to wait for more than an hour, so he abandoned it and turned to eat a stir-fry across the street.

The next afternoon, I went again after an hour’s waiting, and I had to have a taste.

The door of the store is the vegetable picking area, and the innermost is the kitchen. Only four or five small tables are placed in the store, and four or five tables are temporarily placed outside. According to the boss, there are only two chefs in the shop, so they are really busy. They have to wait for about 40 minutes at almost any time, especially at lunch, and it starts an hour.

Eating here is like playing a game of breaking the barrier. In the crowded corridor of "make way, pass", it is difficult to get food, queue and so on, and this first level is considered to have passed.

After paying, getting the number plate, leaving the phone number, and roughly calculating the waiting time, the boss said to the waiting diners that "you can go around nearby first" has become a fixed process.

I interrupted and went to this mala Tang restaurant twice. Although the waiting time is really too long, I can feel the temperament of the small shop run by the northwest people is still different. The whole is a chaotic and orderly atmosphere. In the face of customers urging inquiries, or waiters busy making mistakes, the boss has no impatience for a moment, and his tone is gentle at any time, very atmospheric and easy to communicate. It is very harmonious for everyone to cooperate with the operation. It is very calm to solve the problem when a problem comes.

Customers who bring puppies to eat mala Tang.

Just look around. It’s not boring compared to a dam. This "street restaurant for workers on Hongxing Road" has many Sichuan restaurants, noodle restaurants and snacks along the street. If you don’t want to wait in line, you can choose many alternatives.

We, who are determined to eat mala Tang, choose to sit in a nearby coffee shop and take out the computer to write the above contents first.

● ● ●

We left at 1:23, and the boss called at 15:00. We walked from the coffee shop and waited for more than ten minutes. Mala Tang finally served.

Mala Tang can choose sweet spicy, medium spicy and spicy. Sweet and spicy were sold out at noon that day, so we chose medium spicy.

Cooked vegetables are covered with black and red peppers and need to be stirred by themselves. According to the boss, this is the Gangu pepper in Tianshui, Gansu, and this is the soul of Gansu Mala Tang.

Gangu County, Gansu Province, is known as the "hometown of peppers". Gangu pepper is a specialty here, and it is also a symbol product of chinese national geography.

The boss reminded me: "Be sure to mix well, and you can add more peppers at any time when there is not enough." Mix the "soul" fully, and this dish will be colored instantly, and the eyes will be greedy first.

When you take a bite, the aroma of chili pepper overflows in your mouth, and the medium spicy is not spicy, but pure. With a variety of vegetarian dishes, it is not greasy to eat. It’s as simple and refreshing as mixing a delicious dip when cooking with water.

However, this oily child will be a little bitter in the end. Therefore, personally, mala Tang can be eaten as a whole, but the expected value is not too great.

A friend who asked not to be named has been to Gansu to eat mala Tang, and said that by contrast, she still thinks Sichuan mala Tang is delicious. "Guess it may be because of geographical reasons. There are many frozen goods in local Mala Tang in Gansu, unlike our small county liver, beef, all kinds of delicious internal organs in Sichuan, and there are not many fresh vegetables. But the lasagna and potato chips are really delicious. "

As for why Gansu Mala Tang is so hot, my friend said, "It was a gust of wind that blew to Chengdu."

In the cupboard of this shop, there are still more vegetables but less meat. However, as my friend said, his dry-mixed juice and wide powder really attracted me the most. The wide flour made of potato flour tastes very soft and glutinous, which is very special.

Look carefully at the broken section, and there is still a little crystal sense. Very well received, which is what I want to eat in the street noodle restaurant.

At three or four o’clock, there were fewer guests in the store. At last, the boss can take a short rest and start to sit by and stir mala Tang for the guests, and he wants to eat it himself. The girl at the next table added two spoonfuls of chili pepper, and she liked the taste very much.

I saw some local people comment: "Although it can’t be completely restored, it still has that taste." I took time to chat with my boss. He said that they came from Zhang Ye and opened in Chengdu a few months before Gansu Mala Tang became popular on the Internet. He didn’t expect it to be so hot himself. The present shop is too small, and a new one may be opened recently. So, if you are greedy, please be prepared to wait, and remember not to rush to the meal. The price/performance ratio of the store is good, so you can try it and eat it fresh.

Editors and photographers can do it.

When the typhoon center passes by, the wind will decrease or stay still for a period of time. Remember that the strong wind will suddenly blow and you should continue to stay in a safe place to avoid the wind.
