Kong Wenchao, a Model Worker in Shaanxi Province: Inheritance and Persistence of the Fourth Generation Model Worker

Inheritance is the persistence of generation after generation.

Persistence is the inheritance from generation to generation.

At the vernal equinox, the plane trees on both sides of Daqing Road sprout new buds, and people coming and going have new hopes for the year.

In the coil workshop of Xi ‘an Xidian Transformer Co., Ltd., a transformer winder with a short head and a yellow helmet is working.be wholly absorbedGround winding.

His name is Kong Wenchao, a monitor of the coil workshop of Xi ‘an Xidian Transformer Co., Ltd., and he is also a "technical master" in the eyes of workers.

After 16 years of winding work, Kong Wenchao has been awarded the honorary titles of "Technical Expert of Central Enterprises", "Excellent Communist party member of Central Enterprises", "Xi ‘an May 1st Labor Medal", "Xi ‘an Craftsman" and "Xi ‘an Technical Model". In 2022, he won the honorary title of "Shaanxi Model Worker" and became the fourth "model worker" who grew up from the position of winding worker in coil workshop.

As a fourth-generation model worker in the same position, Kong Wenchao’s master is Zeng Guorong, a model worker in Shaanxi Province, Wang Wenge, a model worker in Xi ‘an, and Ding Jianguo, a model worker in Shaanxi Province. This kind of "mentoring" has also opened a new chapter in the winding work.

As a new generation of winding inheritors, Kong Wenchao told reporters: "If you want to be a model worker all day, you will definitely not be a model worker! Model workers are made, not imagined! "

"Transformer is the key equipment in the whole power system, which is directly related to people’s daily life and even national security, and the coil is like the’ heart’ of the transformer. The quality of the coil directly determines the quality, performance and service life of the whole transformer product. As a transformer winder, I must pay attention to every detail in production in my work. I am good at observing and summing up, so that I can create exquisite products. " Kong Wenchao’s quality of Excellence has made him achieve a good result of 100% passing rate of coil inspection for many years, which has been well received by users.

Kong Wenchao is constantly growing his talents, accumulating experience in research and experience, leading the team in emergencies and dangers, and refreshing the record of UHV in China and even the world again and again with his rough and exquisite hands.

In recent years, with the rapid development of the national UHV AC/DC project, the production and manufacturing of UHV AC/DC transformers have shown a trend of scale and batch, and high-end products have been started intensively, so the quality control of coil manufacturing process is more important.

In the production process of 800 kV converter transformer in the "Northern Shaanxi-Wuhan" UHVDC transmission project, the insulation of wire paper is very thin, and the insulation layer on the inner diameter side of the coil is easy to be damaged if the wire cake is tensioned at the bottom of the coil, but it is extremely difficult to find in quality inspection.

Kong Wenchao noticed this situation. Every time the wire cake was tightened in the winding process, he used a small piece of 0.5mm cardboard to guide the S-bend at the bottom of the coil and the inner diameter brace, which perfectly solved the problem of wire wear.

The workmates don’t understand his "reinventing the wheel" and there is no requirement for the craft. Why bother asking for it? Kong Wenchao said: "A small cardboard is nothing, but we all have UHV products in our hands. If something goes wrong because of the insulation damage of the conductor paper package, the reputation of the enterprise will be damaged, and the construction of national key projects will be affected. Adding cardboard to guide is just a little effort, so why not? "

In 2019, in the production of 1000KV 200 MVAR controllable shunt reactor in the "Zhangbei-Xiong ‘an" 1000 kV UHV AC power transmission and transformation project, Kong Wenchao took the initiative to undertake the winding task of the coil of the project. This product was the controllable shunt reactor with the highest voltage level and the largest capacity in the world at that time. He carried forward the spirit of artisans, worked as hard as making handicrafts, repeatedly verified and worked out the best scheme, which effectively solved the quality problem of product processing and ensured the production progress.

Technological innovation is the lifeline of enterprise’s sustainable development, and it is also the key factor to enhance enterprise’s international competitiveness. Kong Wenchao made bold innovations in combination with the actual work, and tried every means to improve production efficiency and constantly optimize the operation plan.

In the process of coil winding, the cake turning step is indispensable, and its speed directly determines the construction period of the product. With the continuous improvement of product voltage grade, the product wire size and yield strength are also constantly optimized, and the difficulty of cake turning increases. It is difficult to meet the processing needs of existing products by continuing to use the traditional cake turning method.

Kong Wenchao understands that only through technological innovation can this problem be solved. In order to improve efficiency, Kong Wenchao repeatedly studied and searched for the best scheme. Technological innovation can’t be stuck in a rut, and sometimes it can be a good idea to find another way. After a lot of verification, Kong Yan made a bold breakthrough, breaking the traditional method, changing the pad before turning the cake into the cake after turning it. In this way, it not only meets the design requirements of drawings, but also improves the efficiency by 60%, creating considerable economic benefits.

Kong Wenchao always said, "I will do a better job after receiving the baton from my predecessors!" He led the team to publish the QC results of "Improvement on the Method of Continuously Turning Cakes for Single or Multiple Conductors", which won the first prize of "Excellent Quality Management Team of National Machinery Industry" and "Excellent Quality Management Achievements of Xi ‘an" respectively, and the research and development projects of "Improving the Utilization Rate of Turning Cakes for Transposed Conductors" and "Improving the Efficiency of Drawing Lines by S-bend" all won the Excellent Achievement Award of Xi ‘an Workers’ Economic and Technological Innovation.

"When I first took the small hole, he was shy and not good at talking, but he was willing to endure hardships and worked hard. The more honor we have now, the more we should be modest and prudent, and guard against arrogance and rashness. As a model worker, he represents not only himself, but also the image of workers in the whole industry. He should play the role of’ mentoring’ and be a skilled person with comprehensive business! " Zeng Guorong, the master of Kong Wenchao, said proudly.

Since January 2020, Kong Wenchao has served as the Standing Committee of the Second Committee of the Lianhu District Youth Federation in Xi ‘an. He pays more attention to sharing his work experience and experience with young comrades, helping more young people grow into talents and injecting new vitality into industrial development.

The four generations of model workers inherited their initial intentions and relayed forward, which is a microcosm of the "Westward Change" inheriting and carrying forward the spirit of model workers, the spirit of labor and the spirit of artisans, and rallying the great strength of the workers and staff.

Report to the 20th CPC National Congress of the Communist Party of China pointed out that we should speed up the construction of national strategic talents and strive to cultivate more masters, strategic scientists, first-class scientific and technological leaders and innovative teams, young scientific and technological talents, outstanding engineers, great craftsmen and high-skilled talents.

The wheel of history runs over the long river of years, and the glory of time is hunting and screaming in the vicissitudes of life. From 1958 to 2024, "Westernization" has gone through 66 years of development, and generations of "Westernization People" have thrived on this yellow land. From starting from scratch to leading the industry, they have made arduous and persistent trekking step by step, created brilliant achievements with the solid steps of stepping on the stone and leaving a seal, and created the immortal legend of "China’s wisdom".

[Li Xiang China] Fully grasp the organization and implementation of the reform task

  "Further comprehensive deepening of reform has been promoted on the basis of comprehensive deepening of reform since the new era, and it has a solid foundation and favorable conditions. We must make good use of the existing reform achievements and important experiences, emancipate our minds, seek truth from facts, keep pace with the times, be realistic and pragmatic, fully mobilize the enthusiasm of all parties, and do our best to organize and implement the reform tasks. " On August 29th, General Secretary of the Supreme Leader further put forward clear requirements for the implementation of the reform at the sixth meeting of the Central Committee for Comprehensively Deepening Reform.

  One point for deployment and nine points for implementation. Since the 18th National Congress of the Communist Party of China, the General Secretary of the Supreme Leader has repeatedly stressed the importance of paying close attention to implementation, admonished the whole party to "make mistakes in the country by empty talk, and prosper the country by hard work", and demanded to "be both a reform promoter and a reform doer". Since the new era, the CPC Central Committee has consistently pushed forward comprehensive and deepening reforms, the economic system reform has made all-round efforts and made many breakthroughs, the reform of democracy and the rule of law has taken significant steps, the reform of the cultural system has been further advanced, the foundation of the people’s livelihood security system has been continuously consolidated, the system of ecological civilization system has been basically established, the reform of the party building system and the discipline inspection and supervision system has made historic breakthroughs, and the reform of national defense and the military has opened up a new situation … … Over the past decade or so, the reform has been transformed from partial exploration and breakthrough to system integration and comprehensive deepening. The key to historic change, systematic reshaping and overall reconstruction in many fields lies in the fact that the whole party has made implementation the focus of promoting the reform work, from the overall design, overall coordination, overall promotion and supervision of implementation at the central level, to the clear tasks, responsibilities, backward schedule and stubble promotion of various departments in various regions, and then to the in-depth supervision of relevant departments, so as to promote the reform with real swords and spears.

  The Central Committee of the Communist Party of China’s Decision on Further Comprehensively Deepening Reform and Promoting Chinese Modernization, adopted by the Third Plenary Session of the 20th CPC Central Committee, closely revolves around the theme of promoting Chinese modernization, and has deployed more than 300 major reform measures in the aspects of economy, politics, culture, society, ecological civilization, national security, national defense and the army, making it clear that all proposed reform tasks will be completed by the 80th anniversary of the founding of People’s Republic of China (PRC) in 2029. The General Secretary of the Supreme Leader has repeatedly stressed that the reform should attach importance to design and planning, and more importantly, it should be implemented. Facing the new journey, the grand blueprint for further comprehensive deepening reform has been drawn. The key to realizing the reform objectives and tasks set by the Third Plenary Session of the 20th CPC Central Committee as scheduled is to do a good job of implementation. The "Decision" clearly puts forward "improving the implementation mechanism of major decision-making arrangements of the CPC Central Committee", and in the last article of 60, it specifically emphasizes that it is necessary to "do a good job in the implementation of reforms with the spirit of nailing nails" and demand that the decision-making arrangements for the CPC Central Committee further deepen reforms in an all-round way. The whole party must be realistic and pragmatic, and dare to do good deeds. Only when all localities and departments shoulder the reform mission bravely and make real efforts in the implementation of the reform can we push the reform forward in depth.

  The meeting of the Central Committee for Comprehensively Deepening Reform deliberated and adopted the Division of Work Plan for the Implementation of the Important Reform Measures of the Third Plenary Session of the Twentieth CPC Central Committee by the relevant departments of the Central and State Organs, which made clear arrangements for the organization and implementation of the reform task and was an important action for the CPC Central Committee to grasp the reform implementation. It is necessary to adhere to the centralized and unified leadership of the CPC Central Committee on reform and strictly implement the system of asking for instructions and reporting. It is necessary to put the strategic focus and priority direction of quasi-reform, and rationally arrange the sequence and timing of reform measures. It is necessary to more closely integrate reform with economic and social development and accelerate the implementation of landmark reform measures. It is necessary to strengthen the integration of reform systems, enhance the consistency of reform policy orientation, actively evaluate the impact on economic and social development, and form a joint force of reform and development. It is necessary to optimize the implementation mechanism of reform and promote the overall coordination of major issues. All leading units and participating units should dare to take responsibility and work hard, strengthen the investigation and demonstration of major reforms, and formulate reform organization and implementation plans. It is necessary to strengthen the work of reform supervision, evaluation and inquiry, and patrol inspection, so as to test the reform with actual results and people’s satisfaction.

  "Formulating a good document is only the first step of the Long March". Further deepening the reform in an all-round way at a new historical starting point is characterized by tight time, heavy tasks and great responsibilities. Leading cadres at all levels should thoroughly study and understand a series of new ideas, new viewpoints and new conclusions of the Supreme Leader’s General Secretary on comprehensively deepening reform, conscientiously implement the spirit of the Third Plenary Session of the 20th Central Committee of the Communist Party of China, make sustained efforts to promote the implementation of various reform arrangements for a long time, and strive to turn the "freehand brushwork" of the Decision into "meticulous painting" and "construction drawing" and constantly write a new chapter in reform and opening up on a new journey.

Vegetables trapped in the ground

  Sun Ze stood in the middle of a piece of 65cm-high queen celery, and the workers behind him were harvesting vegetables as far as the eye could see. He is a vegetable grower in Cao County, Heze, Shandong Province.

  At 6 o’clock on the morning of November 23, he went to the field, bent down, bowed his head, cut vegetables, bagged, and creaked. Busy until 11 o’clock in the evening, coming out of the ground, Sun Ze and his workers carried bundles of celery to the car, which were packed according to size and category, with a bag of 35 kg and a bag of 2 kg. Celery piled up in front of him, Sun Ze wore dark circles, frowned at the time, and returned to the vegetable field.

  Although workers were invited to help with the harvest, Sun Ze couldn’t stop for a moment. According to the weather forecast, the lowest temperature in Cao County will reach MINUS 5 degrees in five days, and he will finish harvesting more than 100 acres of vegetables before the cold air arrives.

  At present, how to sell vegetables is his worry.

  In Sun Ze’s vegetable field, workers are harvesting celery. The pictures in this article are all provided by the respondents.

  "vegetables can’t be sold"

  On November 18th, Sun Ze posted a short video on the social platform with the words, "The boss who wants to buy food can’t come, and the one who wants to sell food can’t sell it. Is a few cents enough for his wages? No way, I can only break the ground. "

  Below this video, someone commented, "I’m from Jinan, and I really want to pull the goods, but I asked, I can’t get down to the expressway, and I have to be isolated when I come back."

  Three years ago, 34-year-old Sun Ze and his friends invested more than 2 million yuan to plant celery, Chinese cabbage, cauliflower and pepper in Pujilian Town, Cao County. In previous years, these vegetables were sent to all parts of the country, and when the market was good, they could sell tens of thousands of kilograms a day.

  Now, the vegetables he harvested can’t be transported outside, some of them are in the ground and some are in the cold storage, and they can only be sent to friends around at a loss of 23 cents per catty.

  At present, there are still high-risk areas of the epidemic in the towns of Qilou and Ancailou within the scope of Cao County.

  The staff of Cao County Epidemic Prevention and Control Headquarters said in an interview on the 24th that since September, local authorities have implemented peer-to-peer closed-loop management for truck drivers. No matter whether it is from high-risk or low-risk areas, truck drivers who go to Cao County must report to the local authorities three days in advance, and the doors need to be sealed until they leave after loading. If you come from a high-risk area, you need 7 days of home isolation or centralized isolation.

  September is the season for vegetables. "There are customers who buy vegetables through me, but it is too much trouble to report to isolation. The car can’t be found, and the locals can’t consume much. " Sun Ze said.

  "The wholesale price outside is not high either," said the staff of the Market Information Department of Caoxian Agriculture and Rural Bureau on the 25th, saying that the unsalable vegetables were not entirely due to the epidemic situation.

  She said that this year is a warm winter, spinach, rape and cabbage are harvested in advance, and the national vegetable harvest is concentrated on the market. In addition, the prevention and control of the epidemic restricted the gathering and population circulation, and the demand decreased, resulting in a decline in vegetable prices.

  Lin Ying, who lives in Zhoukou, Henan Province, is also worried about the sales of vegetables in greenhouses this month. In the last ten days, several vegetable dealers she contacted by phone all said that "(the driver) won’t let go of the highway intersection and can’t get in."

  Lin Yingjia is a "big land-owner", with more than 200 mu of land, of which wheat accounts for 170 mu. The 40 acres of baby cabbage and more than 10 acres of spinach planted in September have matured.

  Lin Ying’s vegetable field.

  At the busiest time, Lin Ying and her husband got up when they heard the cock crow, and went to work in the fields, so they couldn’t eat breakfast. The output of vegetables is good this time. In normal times, she would laugh happily, but this year she can’t laugh. The year before last, the baby dish cost 3 cents a catty, last year, it cost 5 cents a catty, and this year it dropped to 2 cents.

  In the same harvest season, Sun Ze spent a whole day in the fields, picking vegetables with 30 workers, each of whom worked 10 hours a day, and an hourly fee was paid to 15 yuan.

  Cao County, where Sun Ze is located, is a large agricultural county in Shandong, and in recent years, it has focused on developing characteristic vegetable production bases. In previous years, Sun Ze’s vegetables were mainly sent to Beijing Xinfadi Market, which is the largest agricultural product wholesale market in the local area, covering an area of 1,680 mu and handling 18,000 tons of vegetables a day.

  This year, Wang Tao, who has been stationed in Xinfadi Market for ten years, rarely receives vegetables from Cao County. He is a native of Cao County, and his home land is rented to others to grow greenhouse vegetables, and his relatives and friends in his hometown also grow vegetables.

  Before the epidemic, trucks carrying goods and delivering goods in Xinfadi were one after another, but now it is much colder. The market only does wholesale, not retail. Wang Tao mainly deals with old customers. "Last year, the amount of travel was 100,000 Jin a day, and this year it was only 10,000 Jin or 20,000 Jin."

  Wang Tao collected cabbage, potatoes, beans, celery and cauliflower from farmers. Potatoes are the best, and they are not easy to spoil. A catty can sell for more than one piece, and other vegetables are mostly two or three cents a catty.

  He calculated the account, and the vegetables were transported from Cao county to Beijing, including the purchase fee, freight, cooldown fee, unloading fee, etc., and the cost was 80 cents a catty. At the current price, it may cost tens of thousands a month.

  "The car won’t run."

  On November 22nd, the cauliflower sold by Wang Tao in the market was shipped from Jining, Shandong. He got up at 3 am to pick up the goods and made nucleic acids at 7 am. A car full of vegetables has been sold for two days, with about half left.

  Wang Tao sells vegetables in Xinfadi.

  Hou Zhi, the driver who delivered the goods to him, came to Xinfadi for the first time. Drivers entering the market need to show their nucleic acids and travel cards within 24 hours, and vehicles should be killed. Vehicles from high-risk areas will have pop-ups and Hou Zhi will be sealed in the cab.

  "Drivers run all over the country, so it’s hard not to pop the window." Hou Zhi told reporters that in order not to let the food rot in the car, it is sometimes necessary to find a driver, and the cost of a driver is about 800 yuan to 1000 yuan.

  A survey report recently released by Xinfadi Market shows that there is obstruction in market logistics. The released vehicles with pop-up windows need to be killed, and the killing ability is insufficient, and the waiting time for killing is long. After xiaosha, the driver is closed for management, and the vehicle needs to find a driver to enter the market, and then drive out of the market and return it to the driver after the transaction is completed.

  There are fewer vehicles willing to carry, and the freight rate has also increased. "The usual freight rate is more than 2,000, and now it has risen to more than 4,000." Wang Tao said that if the vegetables were not sold out that day, he would have to pay the driver 300 yuan an extra day’s overtime fee.

  On November 18, Xinfadi issued a notice saying that the "Turnover Zone 2" in the market had been unsealed, and vehicles suspended from other places could return to the Turnover Zone 2 for trading.

  Wang Tao and his wife rented a 10-square-meter bungalow in Xihongmen, and the rent was 1,700 yuan per month. Xihongmen is about 10 minutes’ drive from Xinfadi Market. On November 23, the residence was closed, and Wang Tao moved to a hotel near the market one day in advance, "I will go back when I unblock it."

  Wang Tao gave Hou Zhi food through the gap in the window. The other party had lived in the cab for two days and put two seals on the door. In the middle of the night, some drivers in the market couldn’t hold back and got off to get some air.

  "get through the low temperature"

  In the comment area below Sun Zefa’s video, there are farmers from Henan, Shandong, Hebei, Gansu and other places to post.

  "(Vegetables) can’t be sold here." Lin Ying heard that someone in the village next door destroyed the food in the ground. "It’s all elders, so it’s estimated that there is no way out."

  Lin Ying is 51 years old. There are three children at home who go to school. Her husband used to work in other places. Since five or six years ago, the husband and wife have been farming for a living. The Chinese New Year is coming soon. Children need tuition and living expenses, and they can’t keep deposits at home. If the vegetables in the field can’t be sold, it is estimated that there will be a loss of 70 thousand to 80 thousand if the cost is included.

  These days, she often goes to the greenhouse alone and walks around the vegetable fields. The doll dishes that grow well make her worry, and she plans to switch to wheat next year.

  "Maybe the price was high the year before last year, and the planting area of some vegetables is a bit large this year." The staff of Caoxian Agricultural Bureau said that the county is mainly guiding farmers to sell at the wrong peak. In a few days, it will rain and snow, and the price of leafy vegetables may rise.

  "For example, celery can be stored and kept fresh for 50 days, and cabbage is also a bumper harvest this year. We first stored it, and then guided the wholesalers to buy it and put it in the fresh-keeping warehouse. At the same time, government agencies, including canteens, helped farmers consume part and buy part. " She said that everyone in her unit bought 50 kilograms of vegetables, and helped farmers connect with the surrounding supermarkets, and some foreign merchants came over.

  On November 19th, Henan Province, where Lin Ying is located, issued 10 measures to help farmers sell vegetables, demanding that "layer upon layer overweight" is strictly prohibited. Transportation departments at all levels strictly implement the policy of "green passage" for the transportation of fresh agricultural products, waive vehicle tolls, and give priority to issuing vehicle passes for vegetable transportation. At the same time, "one vehicle, one license and one line" can be implemented in areas where passes are enabled, and vehicles can make multiple trips within the validity period.

  On November 21st, the Agriculture and Rural Bureau of Caoxian County also announced that in order to facilitate the majority of vegetable farmers to grow, manage and sell vegetables better, if they have technical problems and sales difficulties, they can call the hotline. According to the Farmers Daily, Cao County is adjusting epidemic prevention measures to unblock traffic arteries and logistics microcirculation.

  "Isn’t it cheap now? You can accept it late." The staff of the agricultural bureau interviewed suggested that "the open-field vegetables should be collected before the cold air comes, and the vegetables that can survive the winter should not be collected as much as possible now."

  At present, Sun Ze still has about 150 acres of vegetables in the field, and he intends to harvest them overnight. Lin Ying is covering vegetables with non-woven fabrics, hoping that they can survive the low temperature.

The Secret of "Network Consumption Trap" The Stealth "Fishing" Website

Facing all kinds of phishing websites, what should we do as consumers? If we are deceived, how can we complain? In the face of refurbished phishing websites, consumers should carefully click on unknown links in social software such as WeChat and QQ, especially beware of QR codes of shopping websites that require scanning. At the same time, consumers should also pay attention to the filing information of the website to avoid bypassing the third-party hosting platform for direct payment. Relevant enterprises should also set up their own fraud complaint and reporting platform.

Main gene seeks to go public, jellyfish gene company stops changing, and consumer-grade gene testing market divides.

With the Maine gene handing over to the Hong Kong Stock Exchange, consumer-grade genetic testing has once again entered the eyes of consumers. According to the data quoted in the prospectus of Main Gene, Main Gene has become the largest consumer-grade testing platform in China. From the specific product content, consumer-grade genetic testing refers to genetic testing for ordinary consumers, which was introduced to the China market around 2015, and 23 Rubik’s Cube and Jellyfish Gene were established in this year. Main Gene, which was established a year later, has become the only company in China that has made a profit in the consumer-grade genetic testing industry.

However, the situation of players on the same track is different. On February 20th, beijing business today reporter combed and found that the content update of jellyfish gene WeChat official account, another company in the industry, stopped in 2020, and its insiders said that personal business was no longer the focus of the company’s business. In September last year, there was news in the industry that Microgene, 23 Rubik’s Cube and Genebao were discussing the merger. The industry believes that the consumer-grade genetic testing market has reached a watershed.

Main gene shock listing

China’s largest consumer-grade genetic testing company is seeking a Hong Kong stock listing. According to the prospectus of Main Gene Disclosure, the company intends to invest the raised funds in the sales, marketing and commercialization of consumer-grade genetic testing and cancer screening services and products, and research and develop pipeline products.

Main Gene is a project hatched by Yu Rong, chairman of Mei Nianda Health. It was established in 2016 and has achieved profitability. According to the data in the prospectus, from 2018 to 2020, Main Gene achieved a total income of 195 million yuan, 123 million yuan and 203 million yuan respectively, and realized a profit of 22 million yuan, 29.7 million yuan and 79.1 million yuan respectively in the same period.

Consumer-grade genetic testing services and cancer screening services constitute two major business segments of Main Gene. Among them, consumer-grade genetic testing service is the revenue pillar of Main Gene, accounting for more than 90% of the total revenue. Consumer-grade genetic testing services for Main Gene include cancer risk assessment services, chronic disease risk assessment services, Covid-19-related testing services and other consumer-grade genetic testing services.

Beijing business today reporter saw in the official mall of Main Gene that the price of a genetic testing product for cancer risk assessment service is 699 yuan. Users take out the oral swab in the product, and each swab rubs the left and right inner walls of the oral cavity up and down about 20 times, then send the sample back to the testing center, and wait for the test report in 15-20 working days.

Main Gene quoted Jost Sullivan’s data in the prospectus, saying that according to the cumulative number of tests, Main Gene is the largest consumer-grade gene testing platform in China, one of the three largest consumer-grade gene testing platforms in the world, and the only enterprise in China that has made a profit in the consumer-grade gene testing industry.

As early as August 2021, Main Gene submitted listing application materials to the Hong Kong Stock Exchange, and then expired, which was another impact on the listing of Hong Kong stocks after its updated materials. In view of the reasons for listing in Hong Kong and the development of the market, beijing business today contacted Maingene, but no reply was received as of press time.

Silent market

Compared with the active phenomena such as price war and financing in 2017-2019, the domestic consumer-grade genetic testing market has cooled significantly in the past two years. The re-listing of Main Gene broke the long-dormant market.

The rapid development of domestic consumer gene testing industry is closely related to the development of American consumer gene testing companies such as Ancestry and 23andMe. As the first and second largest consumer-grade genetic testing companies in the world, Ancestry and 23andMe were established in 1996 and 2006 respectively. According to industry insiders, the industry developed rapidly around 2015, and a large number of domestic enterprises emerged, following the example of the United States and launching a large number of entertainment projects such as ancestral testing.

Microgenes, 23 Rubik’s Cube and Jellyfish Genes, which entered the market early in China, were all established in 2015. At the beginning of their establishment, they also focused on ancestral analysis, including genetic risks and drug reactions. In order to open the market and gain more users, the industry has experienced price wars. In August 2017, 23 Rubik’s Cube reduced the original standard package price of around 1,000 yuan, and the package price dropped from the previous 999 yuan to 499 yuan. Subsequently, the micro-gene followed suit and lowered the product price.

The heat has gradually warmed up. The three companies that were established earlier have successively obtained financing in 2018, and the industry has also welcomed new players. In January 2018, Microgene announced the completion of the B round of financing, and Jellyfish Gene completed the A round of financing. In March of the same year, 23 Rubik’s Cube announced the completion of the B+ round of financing of 100 million yuan. This year, Anzhen Health and Genebao were established successively. In October 2019, Genebao completed a series of financing of nearly 100 million yuan.

However, since 2020, there has been no new financing news from the industry. In the eyes of the industry, the consumer-grade genetic testing industry has developed late, and the domestic market is not fully aware of personal genes. Difficulties in obtaining customers and making profits have always been the pain points. Affected by the epidemic, the business development of companies has also been affected. In 23 Rubik’s Cube official micro, a consumer once pointed out how to prevent and control risks in saliva sample transportation; When testing in the laboratory, whether there are relevant protective measures and other issues are questioned.

Market differentiation

Impact on the capital market, holding a group to keep warm … The domestic consumer-grade genetic testing market began to differentiate.

Relying on the great health of the United States, the main gene has developed rapidly. According to the prospectus, in 2020, Main Gene conducted 2.7 million genetic tests, accounting for 65.8% of the market share (according to the number of tests).

In September last year, it was reported in the industry that Microgene, 23 Rubik’s Cube and Genebao were discussing the merger. Zheng Qiang, the founder of Microgene, confirmed the news to China Entrepreneur, but did not disclose the specific progress. In view of the progress of the negotiation, beijing business today reporter contacted Gene Bao, Microgene and 23 Rubik’s Cube respectively, and Microgene CTO Chen Gang said "I don’t know this matter". As of press time, Genebao and 23 Rubik’s Cube have not yet replied.

The development of jellyfish genes has also changed. The official Weibo of Jellyfish Gene stopped on June 28th, 2019. Under the last Weibo, some consumers asked questions about the delayed results of the genetic test report and the inability to download the App, but Jellyfish Gene did not reply to the above comments. The wechat WeChat official account of Jellyfish Gene stopped in February 2020 and was renamed as "Jellyfish Life Coach" in June 2021. So far, there is no new content update.

For business development and other issues, beijing business today reporter contacted Zhao Nan, co-founder and CSO of Jellyfish Gene. As of press time, the other party has not responded yet. Beijing business today reporter learned from the staff of Jellyfish Gene I that Jellyfish Gene’s business is still in progress, but its business focus is not on personal business. Earlier, an executive of Jellyfish Gene told the media that the company was still providing genetic testing services, but the business of "burning money" had stopped.

Simulcast+| Not enough after watching the military parade? The world military movement is coming.

[simulcast+]Recently, "News Network" reported the "Village Opening" ceremony of the Military Games Village, and 553 members of the China delegation became the first group to move in, which also marked that all the pre-competition preparations for the Wuhan Military Games were ready.

Athletes' Village of Military Games

Athletes’ Village of Military Games

The 7th military world games held in China will be held in Wuhan from October 18th to 27th. The Wuhan Military Games will be attended by delegations from 110 countries. It will be the largest sports meeting with the largest number of participants and the most influential in the history of military world games.

The majestic National Day military parade is still fresh in my mind, and the news that the military games will be held soon brings our expectations into the sports field. But have you heard of this military world games, which is called the "Military Olympics"? Lianjun will take you to know.

"Wu" and "He" are the names of peace in military sports meetings.

Modern sports seems to be synonymous with peace and friendship. At the beginning of its birth, it was inextricably linked with war and soldiers. It prevailed in the ancient Olympic Games in ancient Greece. Athletes took soldiers as the main body, such as running, wrestling, mixed fighting, horse racing, chariot racing, pentathlon (sprint, long jump, discus throw, javelin throw, wrestling) and so on. Just listening to the names, they carried a certain military brand.

At that time, in order to allow athletes to participate in the four-year Olympic Games safely, the city-states agreed to suspend military operations during the Games. This is the famous "Olympic Truce". Thus, the ancient Olympic Games became a grand gathering for peace and friendship, which was independent of the war environment at that time.

In this way, sports has found a balance between the two contradictory human relations, namely "war" and "harmony". The birth of military world games is the product of human reflection on war and pursuit of peace. To commemorate the 50th anniversary of the end of the Second World War and the signing of the Charter of the United Nations, the first military world games was held in Rome, Italy, from September 4 to 16, 1995. At that time, 4,017 military athletes from 93 countries and regions participated in the competition and launched a competition without smoke.

On September 4th, 1995, the first military world games was held in Italy.

This is the first time in history that the armies of all countries in the world have gathered in a sports event in a peaceful environment, which coincides with the 50th anniversary of the end of World War II. In 1995, countries around the world held a massive commemorative event. In order to celebrate the victory of the world anti-fascist war and the lasting peace brought by the founding of the United Nations, this tournament was praised as "a peace celebration with special significance in the history of the world military".

In 1999, the second military world games was assembled in the Balkan Peninsula, where the war had just stopped for less than two months. Soldiers from 82 countries gathered in Zagreb, the Croatian capital, to spread "peace" under the blazing flame.

On August 8, 1999, the second military world games was held in Croatia.

Who is the strongest in previous military games?

Like the Olympic Games, the military games are held every four years, but the participants are different: the athletes participating in the military games are all active soldiers from all countries; The project settings are different: there are comprehensive Olympic events, military pentathlon, navy pentathlon, air force pentathlon, orienteering and skydiving.

Soldiers are born to be half athletes, do not hold weapons, and the sports competition between them is still full of firepower.

The Russian delegation won the first military games with 62 gold medals, 28 silver medals and 37 bronze medals, and Russian swimmer Dennis pankratov was named the best athlete in this military games. The host Italian military sports delegation won 22 gold medals, 16 silver medals and 13 bronze medals, ranking second in the medal list.

Our army sent a delegation of 191 people, including shooting star Xu Haifeng and swimming world record holder He Cihong, and won 13 gold medals, 21 silver medals and 15 bronze medals, ranking third. The first appearance of our military athletes on the international military arena made the world sit up and take notice.

After that, the top four gold medals in previous military games were ranked as follows:

2nd session: Russian, China, Italian and Croatian (hosts)

The 3rd session: Russia, China, Italy (host country), Ukraine.

The 4th session: Russian, China, German, Italian.

5th session: Brazil (host country), China, Italy and Poland.

6th: Russia, Brazil, China, South Korea (host)

On the whole, Russia has outstanding strength, ranking first in the first four sessions, not participating in the fifth session for some reason, and dominating the sixth session with great advantages. China won the second place in four sessions and the third place in two sessions, ranking second only to Russian. Italy was in the top four in the first five sessions, close to China, and fell to the eighth in the sixth session. Brazil’s first four sessions were unknown, and the fifth session won the championship with the benefit of the host country without Russia’s participation; However, the sixth session can still be ahead of China, and its strength should not be underestimated.

Just like the name of the torch of the Wuhan Military Games-"Glory of Peace", soldiers from all over the world gather here to pursue glory, ignite dreams and convey "peace, development and friendship" through sports.

Our military delegation is fighting at home this time, and it remains to be seen whether it can achieve good results again.

"Create military glory and build world peace"

2019 coincides with the 70th anniversary of the founding of People’s Republic of China (PRC). Holding a grand, warm, simple and pragmatic military games will be a gift to the 70th birthday of the motherland. This is the first time that China has hosted a comprehensive international military event, and it is also the largest international sports event held in China after the Beijing Olympic Games.

This year’s military games will be the first time to hold all competitions in one city, the first time to build an athletes’ village, and the first time to welcome as many as 27 competitions. At that time, nearly 10,000 active servicemen from more than 100 countries will compete on the same stage. Our army will send more than 400 athletes to the 7th military world games.

"Creating military glory and building world peace" is the slogan of this military games, and we are ready. Let’s gather for peace, pass on friendship through sports, and look forward to a perfect game together in less than a week. (Source: News Network, Liberation Army Daily, China Military Network)

Requirements and points for attention of postgraduate insurance: how to successfully send graduate students?

The number of guaranteed research places is issued by the Ministry of Education every year according to the situation, and it is generally announced in early September. The number of research places in each university is relatively fixed and will not change much. The online statistics of the university’s insurance research rate is only the number of insurance research divided by the number of students enrolled in that year, and it does not represent all universities.

The actual number of research places will be adjusted according to the employment situation. In 2020, for example, the global employment situation is grim due to the impact of the COVID-19 epidemic. Many companies have closed down and a large number of employees have lost their jobs, and fresh graduates are facing great employment pressure. In order to alleviate this situation, the Ministry of Education has made it clear that it will expand the enrollment of graduate students.

The determination of the number of research places is not imaginary, but allocated according to the actual situation. The Ministry of Education will comprehensively consider the enrollment plans of various universities, the development needs of disciplines and majors, the employment situation and other factors, and rationally divide the number of postgraduate places.

It is very important for students who want to take part in research, to understand the principles and methods of quota allocation. You can get the latest information on the number of places for research by paying attention to the relevant policies and notices of the Ministry of Education and consulting the graduate admissions office of your school.

When applying for postgraduate insurance, students need to prepare personal materials and application forms in advance, and fill in and submit them according to the requirements of the school. At the same time, it is necessary to pay attention to the policies and requirements of each university to understand the specific application process and evaluation criteria.

In addition, students can improve their comprehensive quality and increase the competitiveness of insurance research by strengthening their academic research and scientific research capabilities. Participating in scientific research projects, publishing academic papers, winning awards, etc. are all points that are conducive to research protection.

It’s not an easy task to guarantee research, which requires students to make a lot of efforts during their college years. However, as long as students maintain a good learning attitude, actively participate in various activities, and constantly improve their overall quality, I believe they will be able to successfully apply for postgraduate studies.

Optimize the corridor layout, upgrade the logistics network, and strengthen the capacity of high-speed rail freight and international air freight.

Modern comprehensive transportation is moving towards higher efficiency

At the eighth meeting of the Central Financial and Economic Committee, the Supreme Leader General Secretary emphasized that the circulation system plays a fundamental role in the national economy, and to build a new development pattern, it is necessary to take the construction of a modern circulation system as an important strategic task.

Transportation is the basic link and important support for building a modern circulation system and smoothing the national economic cycle. It is necessary to build a modern comprehensive transportation system, form a unified and open transportation market, optimize and improve the layout of comprehensive transportation corridor, strengthen the capacity building of high-speed rail freight and international air freight, and accelerate the formation of a safe and efficient logistics network with internal and external connectivity.

Transportation connects the two ends of production and consumption, which is the basic link and important support for building a modern circulation system and smoothing the national economic cycle. At the eighth meeting of the Central Financial and Economic Committee, the Supreme Leader General Secretary proposed to build a modern comprehensive transportation system, form a unified and open transportation market, optimize and improve the layout of comprehensive transportation corridor, strengthen the capacity building of high-speed rail freight and international air freight, and accelerate the formation of a safe and efficient logistics network with internal and external connectivity.

What is the modern comprehensive transportation system like? How to speed up the construction? The reporter conducted an interview.

Lay a solid foundation-

Optimize and improve the layout of comprehensive transportation corridor.

Logistics is an important aspect of circulation, and transportation is an important support of logistics. Since the beginning of this year, a series of major transportation projects have been accelerated, which is expected to make the transportation skeleton stronger: looking at the highway, the construction of projects such as Baoshan-Lushui Expressway in Yunnan, Pingliang-Tianshui Expressway in Gansu and Yanjiang Expressway in Sichuan has been stepped up; Looking at the railway, the daily average number of trains on Haoji Railway, a new channel of "North Coal to South Transportation" newly opened to traffic last year, has increased to 20, and sichuan-tibet railway is also advancing in stages; Looking at aviation, the construction of new airports in Chengdu, Qingdao and other places is busy …

"After years of development, China’s transportation infrastructure construction has made remarkable progress, and the mileage of expressways and high-speed railways both ranks first in the world. However, compared with the requirements of building a new development pattern and smoothing the national economic cycle, there is still much room for improvement." Zhang Xiaodong, a professor at the School of Transportation of Beijing Jiaotong University, said.

Next, how to optimize and improve the layout of comprehensive transportation corridor?

We should pursue comprehensive efficiency. Zhang Xiaodong analyzed that at present, the roads and railways in the eastern and central regions of China are relatively developed. In the future, we should focus on improving the connection level of existing transportation facilities and give full play to the comprehensive efficiency of modern transportation. "Comparatively speaking, the transportation network in some central and western regions is not perfect enough. It is necessary to work out the layout at the height of connecting the east, west, sea, land and air, and connecting home and abroad, helping to form a unified domestic market and connecting more people and logistics into domestic circulation and international circulation. This idea is reflected in the Silk Road Economic Belt in the north, the 21st Century Maritime Silk Road in the south, the new land and sea channel in the west that connects the Yangtze River Economic Belt in coordination, and the China-Europe train connecting Asia and Europe. "

We should strengthen the weak links. "Compared with some developed countries, the number of airports in China is still small, especially in urban agglomerations such as Beijing-Tianjin-Hebei, Yangtze River Delta and Pearl River Delta, where passenger and cargo transportation demand is strong." Li Xiaojin, director of civil aviation university of china Institute of Air Transport Economics, believes that relevant parties should appropriately expand the supply of airspace and ground resources and strengthen airport construction.

Wu Chungeng, spokesman of the Ministry of Transport, told the reporter that the Ministry of Transport will deploy and speed up the construction of comprehensive transportation corridor, hubs and network systems, focusing on promoting major projects such as the river-crossing and sea-crossing highway system along the border and coast, the new land-sea passage (Pinglu) canal in the west, the Xianggui canal and the Jiangxi-Guangdong canal, and promoting the construction of "four good rural roads", enhancing the capacity and toughness of the main passages, and enhancing the traffic density and vitality.

Make up the short board-

Strengthen the capacity building of high-speed rail freight and international air freight.

On July 19th, with the entry of a new all-cargo plane, SF Airlines’ cargo fleet expanded to 60 after 11 years of "sailing".

Since the outbreak, many passenger flights have been greatly reduced, but SF air cargo is still busy and efficient, transporting a large number of epidemic prevention and living materials for various places, which shows the advantages of fast transportation speed and high stability of all cargo planes.

Due to the late start, China’s air freight still has shortcomings. "According to the statistics of 2019, in China’s air cargo, passenger aircraft belly cabin transportation is still the main mode, accounting for about 70% of the cargo volume, and the proportion of domestic routes is higher, reaching 82%." Li Xiaojin said that improving the capacity of air freight, especially international air freight, is conducive to maintaining the stability of China’s industrial chain supply chain and enhancing the ability of China’s economy to resist risks.

How to make up the short board? "With the acceleration of consumption upgrading and the release of domestic demand potential, the transportation demand of high-value products such as electronics, fashion and medicine will gradually increase, driving the development of air freight." Li Xiaojin suggested that relevant regions and departments should take advantage of the situation and strengthen their support, such as developing freight airports by planning new construction, revitalizing resources and "bringing goods by passengers", and encouraging air freight enterprises to expand their fleet size and become integrated logistics enterprises, etc. "Gradually build an air freight facility layout with perfect functions, reasonable layout and smooth connection and an air freight network system that reaches the whole world."

Like the aviation field, railway transportation used to have a tendency of "emphasizing passengers over goods". "In recent years, after the continuous advancement of transportation structure adjustment, railway freight has stabilized and rebounded." Zhang Xiaodong told reporters that in 2018, the proportion of railway freight volume in the total social freight volume has increased. "Although there is progress, there is still a big gap between the ideal level and it needs to be strengthened."

In railway freight, high-speed rail freight is the most "young". "In recent years, China State Railway Group Co.,Ltd. has done a lot of exploration, such as using high-speed trains that don’t pull passengers to transport goods, taking goods with the car in some vacant large luggage storage places, or choosing some time slots and routes with low attendance rate to make room for freight. In addition, dedicated high-speed rail freight EMUs are also being piloted. " Zhang Xiaodong believes that high-speed rail freight has great potential and space. "In the long run, China’s use of the world’s most developed high-speed rail network to develop high-end freight is conducive to providing efficient, energy-saving and stable transportation support for the smooth circulation of the national economy."

The key to making high-speed rail freight "fire up" is to promote market-oriented reform. In 2018, China Railway Express and SF established China Railway SF through mixed reform, which organically combined their railway transportation resources and terminal distribution capacity, and the "high-speed rail" product launched also achieved "door-to-door" full service. Zhang Xiaodong said, "In the past, railway freight transportation focused on’ station to station’. The development of high-speed rail freight requires railway enterprises to deepen reforms and effectively improve transportation timeliness, train stability and integrated logistics integration. "

Optimize the structure—

Accelerate the formation of a safe and efficient logistics network with internal and external connectivity.

At 12: 25 on October 8th, the No.34114 train loaded with more than 2,900 tons of soybeans and corn left the container center station of Qinzhou Railway in Guangxi for Yiliang North Station in Kunming. So far, the container handling capacity of the new western land and sea passage (Qinzhou Port) has exceeded 200,000 TEUs.

The new land and sea passage in the west is the most convenient sea passage for goods in many western provinces. In recent years, thanks to the rapid development of rail-sea combined transport, all kinds of goods and containers will soon be able to sail out to sea after arriving at the port by train from the hinterland of the west. The rapid development of multimodal transport has further improved the overall transportation efficiency in China.

The progress is obvious, and the gap still exists. Wu Chungeng analyzed that at present, the structural contradictions of China’s transportation modes are still outstanding, especially in the freight field. Roads have undertaken too many medium-and long-distance goods and bulk goods transportation. "The connection of various transportation modes also needs to be strengthened, the conversion efficiency is low, the development of multimodal transport is lagging behind, and the terminal circulation is not smooth."

Generally speaking, China’s comprehensive transportation structure still needs to be optimized, and the key is to accelerate the formation of a safe and efficient logistics network with internal and external connectivity. "Only by integrating the smooth transportation network with the internal and external logistics network can we effectively support the modern circulation system." Zhang Xiaodong said.

On the one hand, it is necessary to connect internally and externally to ensure safety.

"What shippers need is door-to-door service, but most Chinese airlines can only provide airport-to-airport service for international freight transportation, especially overseas, and there is still a lack of necessary logistics network layout." Li Xiaojin said. Wu Chungeng said, "We will speed up the construction of the international logistics supply chain system, improve the transshipment system and ground service network, improve the support capacity of key channels and nodes, and do a good job in ensuring the key strategic materials."

On the other hand, it is necessary to connect smoothly and pursue high efficiency.

"In Zhengzhou Airport Economic Zone, the airport freight area and Foxconn factory are connected by railway, and electronic products can get on the train and board the plane just after leaving the workshop, which is very convenient." Li Xiaojin told reporters that at present, less than 20% of the more than 200 domestic airports are connected to railways, and most of the tracks are still used to transport passengers. "There is great potential for air-rail combined transport."

Wu Chungeng said that in the next step, China will strengthen the construction of special railway lines, water transport infrastructure, multimodal transport hub stations and collection and distribution systems, and make overall plans to study the proportional relationship between high-speed rail, ordinary rail, urban rail transit, aviation and water transport, and comprehensively improve the service level of multimodal transport.

  More than 500 nails found on the campus of Tokyo Elementary School (Tokyo Metropolitan Television)

  Overseas Network May 15thAccording to a report by Tokyo Metropolitan Television on the 15th, students in a primary school in Suginami District, Tokyo, Japan were recently scratched by nails on the ground. After searching, more than 500 nails were found on the campus of this school. With further inspection, nails were found in many schools in Suginami District.

  According to the Education Committee of Suginami District, the school involved is Ogikubo Primary School. In April this year, a child slipped in PE class, was scratched by a 12.5 cm nail on the ground, and had more than 10 stitches in his knee. Subsequently, the school used metal detectors to detect in the school, and found a total of 544 nails and hooks, which have all been removed. According to the school, the school will use marks, nails or nails to line up neatly during sports meetings and other activities, and forget to withdraw after using them.

  The principal of the school involved has apologized to the injured children and parents. After the incident, the District Education Committee asked the primary and secondary schools in the whole district to make an emergency inspection, and many schools reported that nails were found on campus. The district education commission plans to introduce regulations requiring schools to stop using nails. (Overseas network Wang Shanning)

Knowledge and comprehensive understanding of avian influenza

  According to the different pathogenicity of avian influenza, avian influenza can be divided into highly pathogenic avian influenza, low pathogenic avian influenza and non-pathogenic avian influenza. Recently, avian influenza caused by H5N1 serotype at home and abroad is called highly pathogenic avian influenza, with high morbidity and mortality and great harm.


  Human avian influenza (hereinafter referred to as human avian influenza) is an acute respiratory infection caused by some subtypes of avian influenza A virus. In May 1997, a 3-year-old child in Hong Kong Special Administrative Region of China died of unexplained multiple organ failure. In August of the same year, it was identified as human influenza caused by avian influenza A virus H5N1 by the US Centers for Disease Control and Prevention and the World Health Organization (WHO) National Influenza Center in Rotterdam, the Netherlands. This was the first time in the world that avian influenza A virus H5N1 infected humans.


  It is generally believed that human beings are not easily infected with avian influenza virus. Although people can be infected at any age, children under the age of 13 account for a high proportion of the infected cases, and their illness is serious.


  The main sources of infection are chickens, ducks, geese and other poultry, especially chickens, who suffer from avian influenza or carry avian influenza virus; But it does not rule out the possibility that other birds will become the source of infection.


  The route of transmission is mainly through respiratory tract, through close contact with infected birds and their secretions, excreta, water contaminated by virus, and direct contact with virus strains.


  Susceptible people generally think that they are susceptible at any age, but the incidence of children under 12 years old is higher and the condition is more serious. People who are in close contact with poultry that died of unexplained illness or infected or suspected to be infected with avian influenza are high-risk groups.


  Patients usually have an acute onset, and their early manifestations are similar to ordinary influenza. It is mainly fever, the body temperature is mostly above 39℃, and the heat course lasts for 1 ~ 7 days, usually 3 ~ 4 days, which may be accompanied by runny nose, stuffy nose, cough, sore throat, headache and general malaise. Some patients may have digestive tract symptoms such as nausea, abdominal pain, diarrhea and watery stools. Severe patients’ condition develops rapidly, and there may be pneumonia, acute respiratory distress syndrome, pulmonary hemorrhage, pleural effusion, pancytopenia, renal failure, sepsis, shock and other complications. Chest x-ray examination of patients can show unilateral or bilateral pneumonia, and a few patients can be accompanied by pleural effusion.


  Avian influenza virus is sensitive to organic solvents such as ether, chloroform and acetone. Common disinfectants are easy to inactivate, such as oxidant, dilute acid, sodium dodecyl sulfate, halogen compounds (such as bleaching powder and iodine agent) can quickly destroy its infectivity.


  Avian influenza virus is sensitive to heat and can be inactivated by heating at 65℃ for 30 minutes or boiling at 100℃ for more than 2 minutes. The virus can survive for one week in feces and one month in water, and it also has viability under the condition of pH<4.1. The virus has strong resistance to low temperature, and can keep vitality for more than one year under the protection of glycerol.


  The virus can be inactivated in 40 ~ 48 hours under direct sunlight, and its infectivity can be quickly destroyed if it is directly irradiated with ultraviolet rays.


  Experts remind that people who have been to the epidemic spot of avian influenza outbreak, or who have close contact with infected poultry and their secretions and excretions, or who are engaged in avian influenza virus laboratory staff, should go to the hospital for examination in time when similar cold symptoms occur during this period to rule out the possibility of avian influenza.


  Clinically, we should pay attention to differential diagnosis with influenza, common cold, bacterial pneumonia, infectious atypical pneumonia (SARS), infectious mononucleosis, cytomegalovirus infection, chlamydia pneumonia, mycoplasma pneumonia, pneumonia epidemic hemorrhagic fever and other diseases.


  Usually, you should pay attention to food hygiene, do not drink raw water, do not eat immature meat and eggs and other foods; Wash your hands frequently and develop good personal hygiene habits. Frequent hand washing is the most effective way to prevent all kinds of viruses, whether common influenza virus or H5N1 virus from invading. Ordinary medical alcohol cotton balls and disinfectant soap can effectively kill bacteria and viruses. Good hygiene habits are the most economical and effective way to prevent various diseases.


  The main route of avian influenza virus transmission is through dead birds, sick birds and their excreta, so chickens and ducks must be bought in regular supermarkets to avoid sick birds and dead birds; Pay attention to food hygiene, and be sure to cook chickens and ducks when eating them. When you buy pet birds in the flower, bird, fish and insect market, you must ensure that the birds are not sick; Wash your hands frequently when raising birds, keep your distance when watching birds, pay attention to air circulation and pay attention to hygiene and disinfection.

  Medical workers and people who deal with avian influenza, as well as those who are physically and mentally ill, should be vaccinated against influenza. Experts believe that injecting human influenza vaccine not only reduces the occurrence of influenza, but also helps to block the combination and recombination of human influenza virus and avian influenza virus.


  November 14th, 2005. The Ministry of Science and Technology announced in Beijing that researchers in China have successfully developed avian influenza vaccine for human use, completed all pre-clinical research work and will soon start clinical trials.
