Which of these five COVID-19 vaccines should I use?

According to the data released by National Health Commission, as of April 3rd, 136.677 million doses of Covid-19 vaccine were reported in all localities.

At present, five Covid-19 vaccines have been approved for use in China. What’s the difference between these five vaccines? Which variety is better? The expert responded.

According to the technical route, the five vaccines are divided into three categories:

One is inactivated vaccine, includeSinopharm Zhongsheng Beijing Company, Sinopharm Zhongsheng Wuhan Company and Beijing Kexing Zhongwei Company. Three inactivated vaccines produced;

The second is adenovirus vector vaccine, forTianjin kangxinuo company Production of adenovirus type 5 vector vaccine;

The third is recombinant protein vaccine, forRecombinant novel coronavirus vaccine (CHO cells).

What is the difference between the three technical routes?

"Inactivated vaccine is a vaccine prepared by a series of purification techniques after the live virus is killed by physical and chemical methods." Wang Junzhi, deputy head of the expert group of the vaccine research and development special class of the State Council Joint Prevention and Control Mechanism and academician of China Academy of Engineering, said that its main feature is that the composition of the vaccine is similar to that of the natural virus, and its immune response is strong, so it has good safety.The vaccine is relatively stable, can be stored at 2-8 degrees Celsius for two to three years, and is convenient to transport; Take two injections of immunization.

"Adenovirus vector vaccine is a live vector vaccine made by taking adenovirus type 5 as a vector, introducing Covid-19 antigen gene and making it through bioreactor." Wang Junzhi said that the vaccine preparation process is relatively simple, and the research and development costs and production costs are relatively low, because it was successfully developed on the basis of the original platform of Ebola vaccine for adenovirus type 5 in our country.Vaccine can induce antibody production and enhance cellular immunity; You can take a single needle immunization.

"Recombinant protein vaccine is to express the most effective antigen components in vitro by genetic engineering. In vitro cells are cells commonly used by engineering cell lines in biological products, similar to industrial fermentation, and finally made into vaccines. " Yan Jinghua, a researcher at the Institute of Microbiology, Chinese Academy of Sciences, said that the whole production process is a process of protein expression and purification, and there is no live virus involved, so the production process is safe and easy for mass production. From the past use process of recombinant protein vaccine and the previous experimental results, the safety of recombinant protein vaccine can be guaranteed, and the adverse reaction rate is relatively low.The vaccine is refrigerated at 2-8 degrees Celsius, which has low requirements for transportation and storage conditions; Take two or three injections of immunization.

Which vaccine is more effective?

Wang Junzhi said that the three routes of Covid-19 vaccine have their own characteristics. No matter what technical route is adopted, the most important thing is to develop a safe, effective and quality-controlled vaccine by combining the characteristics of antigen and pathogen, which is the key criterion for vaccine success.

He Qinghua, a first-class inspector of National Health Commission CDC, said that at present, all Covid-19 vaccines listed in China have been examined and approved by the drug regulatory authorities.Its safety and effectiveness are supported by certain data, so you can safely inoculate.

How to choose single needle and double needle?

Shao Yiming, a researcher at China CDC, introduced,For people who need to go to epidemic areas for temporary or urgent tasks, but don’t have enough time to wait, it is more suitable to inject single-needle adenovirus vector vaccine. In addition, single-needle inoculation can avoid the poor immune effect caused by failure to get the second needle for various reasons.

Single-needle vaccine also has shortcomings. Shao Yiming suggested that the immune response intensity induced by single-needle adenovirus vector vaccine is generally weaker than that induced by two-needle vaccine, and it is no problem in preventing early epidemic virus. When it is replaced by late mutant virus, the protection efficiency will mostly decrease. Therefore, when choosing a vaccine, we should make a comprehensive judgment and scientific decision according to the specific situation of the people to be protected and the latest monitoring data of local epidemic viruses.

Why is vaccination first for young people and then for the elderly?

According to an interview with Dr. Zhang Wenhong from CCTV News: ① The elderly are less socially active than young people and may not be easily infected; ② The main task of epidemic prevention and control in China is to prevent external import and internal rebound, and most people who are exposed to viruses, such as doctors, are young people; ③ The incidence of other diseases in the elderly population is high, which needs more clinical research data to support.

I don’t have to fight when everyone else has?

Wen Yumei, an academician of China Academy of Engineering and a professor at Shanghai Medical College of Fudan University, said that vaccine is the only weapon that can completely control an infectious disease. Vaccination not only protects individuals from the pathogens of infectious diseases, but also limits the spread of pathogenic microorganisms in groups.

She pointed out that it is a good time to get COVID-19 vaccine. Because there is no epidemic in China, and most people are in good health, vaccination can protect everyone well. "We should take precautions and protect ourselves first."

In view of the mentality of some people that "I don’t need to get vaccinated when everyone else has finished", Wen Yumei said that this is a misunderstanding. The immune barrier formed by the population (generally about 70% to 80% people need to be vaccinated according to the Covid-19 transmission coefficient) can effectively control the spread of the epidemic, but it does not mean that individuals will not be infected. "Others are vaccinated because others are protected. If you are not vaccinated, you still have the risk of being infected."

Reminder: Don’t believe this message.

Recently, people across the country received a short message signed "Center for Disease Control", saying that "COVID-19 vaccine can be vaccinated by appointment" and attached an appointment link.

At first glance, it looks realistic, but you can see the flaw if you look closely. Yes, this is a scam message. If you receive a similar message, don’t believe it! Please delete it at the first time, don’t click on the link inside, and don’t fill in personal information.

Major banks take the lead in opening a new round of deposit "interest rate reduction"

◎ Reporter Zhang Jones Chang Peiqi

A new round of deposit "interest rate cut" opened. On May 20th, major banks such as Industrial and Commercial Bank of China, Agricultural Bank, Bank of China, China Construction Bank, Bank of Communications, Postal Savings Bank, China Merchants Bank and China Everbright Bank announced that they would lower their deposit interest rates.

Take China Construction Bank as an example. In terms of demand deposits, the interest rate is lowered by 5 basis points to 0.05%. In terms of time deposits, the interest rates of lump-sum deposit and withdrawal for three months, six months, one year and two years were all lowered by 15 basis points, to 0.65%, 0.85%, 0.95% and 1.05% respectively; The 3-year and 5-year interest rates were lowered by 25 basis points to 1.25% and 1.3% respectively.

In the opinion of analysts, this round of deposit interest rate reduction is large, which will play multiple roles. Ceng Gang, chief expert and director of the Shanghai Finance and Development Laboratory, said that for banks, lowering the deposit interest rate can reduce the cost of capital and increase the net interest margin, thereby enhancing profitability and capital accumulation capacity and providing space for subsequent expansion of credit supply; For the real economy, the decline in deposit interest rate will be further transmitted to the loan interest rate, which will help reduce the financing costs of enterprises and residents and help stabilize growth; The flow of funds to entities and capital markets will help to better support innovation, entrepreneurship and industrial upgrading.

This round of deposit "interest rate cut" will reduce the cost of bank debt. Wen Bin, chief economist of China Minsheng Bank, said that this is the seventh round of deposit listing interest rate reduction led by state-owned banks and stock banks. The reduction of deposit interest rate is greater than the decrease of loan market quoted interest rate (LPR) on the same day, which helps to reduce the debt cost of banks.

"The decline in the loan interest rate will further increase the downward pressure on the bank’s net interest margin and reduce the debt cost. Deposits are an important source of liabilities for banks, so it is necessary to lower the deposit interest rate to stabilize the bank’s net interest margin and improve the sustainability of banks’ services to the real economy. " Lou Feipeng, a researcher at the Postal Savings Bank, said.

As an important indicator to measure the profitability of banks, the net interest margin has continued to decline in recent years. According to the data of the General Administration of Financial Supervision, in the first quarter of 2025, the net interest margin of commercial banks was 1.43%, which was 0.09 percentage points lower than that in the fourth quarter of 2024, hitting a new low.

Wang Qing, chief macro analyst of Oriental Jincheng, said that after the major banks cut the deposit interest rate and led other banks to follow up the adjustment, the overall deposit interest rate will be lowered by 0.11 to 0.13 percentage points, which can basically cover the impact of the LPR reduction on the bank’s asset-side income, thus stabilizing the bank’s net interest margin.

"This LPR reduction and deposit interest rate reduction, the reduction of debt cost is higher than the reduction of return on assets, which is rare. This is also the largest reduction in deposit interest rates in recent years. On the whole, the impact on banks is positive. " Lin Yingqi, deputy general manager of the research department of CICC and banking analyst, said.

The reduction of deposit interest rate will also have an impact on residents’ assets. Dong Ximiao, chief researcher of Zhaolian, said that with the lower deposit interest rate and the improvement of residents’ expectations, the attractiveness of the capital market and wealth management market will be further enhanced, which will help promote the healthy and sustainable development of the capital market and wealth management market. If investors want to pursue steady income, they can appropriately allocate cash management wealth management products, money funds, national debt and so on.

Talking about the follow-up rhythm of deposit "interest rate reduction", Ceng Gang said that under normal circumstances, large state-owned banks often take the lead in adjusting deposit interest rates because of their stable debts and strong customer base, setting an "anchor" for the market and leading the adjustment of the industry. Subsequently, small and medium-sized banks followed suit to maintain interest margins and refer to market competition.

In-depth implementation of seed industry revitalization action, listed companies compete to launch biological breeding track

Source: shanghai securities news.

  On the occasion of spring ploughing, the No.1 document of the Central Committee was released.

  Seeds are the "chip" of agriculture, and good seeds will yield abundant grain. This year’s No.1 Document of the Central Committee on the in-depth implementation of the seed industry revitalization action has sparked heated discussions in the seed industry.

  On February 14th, a number of senior executives of listed domestic seed companies told shanghai securities news that this year’s Document No.1 of the Central Committee pointed out the direction for the application of biological breeding technology in China from the level of industrialization, which will promote the transformation of seed industry and enterprises from technology reserve to application, accelerate the development and application of new biotechnology, and further enhance the level and competitiveness of self-reliance and self-reliance of seed technology in China.

  The industrialization of biological breeding is expected to speed up again

  This year’s No.1 Document of the Central Committee pointed out that it is necessary to further implement the seed industry revitalization action. Including: fully implementing major biological breeding projects, solidly promoting the national breeding joint research and livestock genetic improvement plan, and accelerating the cultivation of high yield and high oil.soybeanNew varieties such as rape with short growth period and salt-tolerant crops. acceleratecornThe pace of soybean biological breeding industrialization, orderly expand the scope of the pilot, standardize planting management.

  "This year, the No.1 Document of the Central Committee pointed out that it is necessary to speed up the industrialization of corn and soybean biological breeding, expand the pilot scope in an orderly manner, and standardize planting management. This has pointed out the direction for the application of biological breeding technology from the industrialization level, which will promote the transformation of China’s seed industry and enterprises from technical reserve to application, accelerate the development and application of new biotechnology, and further enhance the level and competitiveness of China’s seed industry science and technology. " On the morning of February 14th,Longping high-techA person in charge said, "The company has continuously increased investment in innovation. Under the guidance of a series of national policies to promote the development of modern seed industry, and in accordance with the requirements of’ standardization, proceduralization, informationization and scale’, it has taken the lead in establishing an enterprise-oriented, market-oriented and Industry-University-Research-closely integrated hybrid rice commercialization independent innovation system in China, covering both domestic and international markets and covering three platforms of biotechnology, traditional breeding and variety testing."

  Previously,Quanyin high-techZhang Conghe, deputy general manager and chief technology officer, said that 2023 is the third year of China’s seed industry revitalization. Since China established the seed industry as a national strategic basic core industry, the seed industry has entered the "fast lane" of accelerated development. A number of large seed companies with scientific research strength have come to the fore. At present, China’s wheat and rice seeds are very competitive internationally, and corn is also catching up with the international level at a high speed.

  A number of heads of listed seed companies said that the tone of document No.1 this year on "accelerating the pace of biological breeding industrialization" not only conforms to the overall situation of food security, but also meets the internal needs of domestic seed industry revitalization.

  It is understood that the advantages of genetically modified seeds are mainly reflected in cost reduction and yield increase. In terms of cost reduction, transgene can be reduced.pesticideThe use cost of. As far as the yield increase is concerned, taking corn as an example, according to the research on genetically modified corn by authoritative organizations, genetically modified seeds can improve the yield of corn. Different transgenic traits have different effects. A single transgenic trait can increase the yield by about 0.5% to 4.4%, and the effect of compound traits is more obvious. For example, the compound traits of corn root worm resistance and herbicide resistance can increase the yield of corn by 7.42%.

  "This year, the No.1 Document of the Central Committee proposed to implement a new round of actions to improve the grain production capacity of 100 billion Jin and to create tons of grain fields. Biological breeding, especially transgenic technology, is an important means to ensure food security and revitalize the seed industry. Many policies and regulations have been issued in China, such as the Measures for the Safety Assessment and Management of Agricultural Genetically Modified Organisms, to prepare for the commercialization of genetically modified organisms. With the approval of varieties, the genetically modified seed industry will usher in development opportunities. " A senior seed industry person told reporters.

  Diversified layout of seed industry leaders is busy with "breeding"

  according toTF SecuritiesThe research report estimates that after the commercialization of genetically modified seeds, the ex-factory caliber of genetically modified seeds (corn and soybeans) in China is expected to reach 43.2 billion yuan, and the profit is expected to reach 13 billion yuan.

  Specifically, among A-share seed listed companies,Dabeinong, Longping Hi-Tech,Fengle seed industryDomestic seed industry head enterprises, such as Quanyin Hi-Tech, will take biological breeding represented by genetic modification as the key layout field of the company in the future.

  Among them, Dabeinong’s transgenic product technology is leading in China. The company directly grasps the technology of genetically modified corn and soybean traits through holding subsidiaries, focusing on the development of genetically modified corn and soybean. The company’s genetically modified corn products mainly focus on the domestic market, while the genetically modified soybean products focus on domestic and South America. At present, the company has cooperated with more than 130 seed enterprises and cultivated more than 200 new biological varieties, which is the leading enterprise with the largest character reserve in China.

  As the leading seed industry in China, Ruifeng 125, Ruifeng 8, nCX-1 and CAL16 declared by Ruifeng Bio, a genetically modified company owned by Longping Hi-Tech, and BFL4-2 jointly declared by Longping Hi-Tech and Institute of Biotechnology of Chinese Academy of Agricultural Sciences, have successively obtained safety certificates for agricultural genetically modified organisms.

  "At present, Longping Hi-Tech has prepared for commercialization in the application of transgenic technology in accordance with relevant national requirements, and has also promoted biotechnology research such as gene editing and whole genome selection according to laws and regulations, and has made good progress."

How does generative artificial intelligence reshape education and teaching in colleges and universities

  From the industrial revolution to the era of digital intelligence, human beings have never stopped to develop new technologies. The increasingly mature generative artificial intelligence has brought many influences to all aspects of the development of human society, and higher education is one of the most significant areas affected by generative artificial intelligence. The influence of generative artificial intelligence on higher education includes but is not limited to assisting teachers in preparing lessons and teaching, promoting students’ autonomous learning, personalized learning and inquiry learning, assisting in paper writing, guiding students to complete homework, exam review, language learning, and improving digital literacy. It can be said that generative artificial intelligence has injected new vitality into higher education and promoted the innovation and development of education and teaching.

  At present, more and more universities around the world are exploring a safe and reliable way to combine generative artificial intelligence with education and teaching, and the trend of integrating generative artificial intelligence into higher education is unstoppable.

Innovation and efficiency improvement: the influence of generative artificial intelligence on higher education

  Generative artificial intelligence expands the space of higher education.First, it enriches the teaching media of higher education. Multi-modal generative artificial intelligence has multiple forms of expression, such as text, voice, picture, video, animation, etc. The training data output by the large model can be used as a shared medium for teachers to prepare lessons, students to learn, evaluate education and discuss with peers. This educational medium with the characteristics of new quality and productivity is recombined with various teaching methods and used flexibly in different educational scenes, making teaching more effective, fascinating and interesting. The second is to expand the diversity of higher education scenes. On the one hand, generative artificial intelligence can further break through the space restrictions such as classrooms and promote the globalization of educational space. In the future, any place connected to the network can be used as a learning space, which will be conducive to the realization of educational equity. On the other hand, generative artificial intelligence enriches the educational scene. For example, giving immediate instructions in the scene of students’ hands-on operation can make students’ practice and theoretical study parallel, thus further promoting the combination of theory and practice. The third is to promote the multi-dimensional interaction of education. Generative artificial intelligence makes the interactive dimension of education no longer limited to direct face-to-face communication, but suddenly increases to the Cyberspace interacting with "man-machine-man". The terminal interface gathers the interactive data of "man-machine" into the network dimension, and then presents it to the physical world after processing. Multi-dimensional interactive space means the increase of interaction frequency among educational subjects and the increase of students’ participation, and the interactive relationship of the combination of reality and reality further expands the educational situation.

  Generative artificial intelligence extends education time and effectively empowers lifelong learning.Firstly, the generative artificial intelligence model relies on its powerful parallel processing ability, which can support multiple learners to participate in learning tasks at the same time, and at the same time provide personalized teaching content and feedback for each learner. This not only improves the timeliness of education, but also greatly expands the coverage of education. Secondly, generative artificial intelligence provides immediate listening, analysis and feedback for educators and educatees. The traditional education model often requires teachers to spend a lot of time correcting students’ homework before giving feedback, which greatly reduces the teaching efficiency. Generative artificial intelligence can provide immediate data support for educators, help managers make more accurate decisions, and provide immediate feedback for learners, help them find and correct mistakes in learning in time, promote the consolidation of knowledge and skills, and cultivate growth-oriented thinking. Thirdly, generative artificial intelligence empowers lifelong learning. On the one hand, generative artificial intelligence has the potential of "virtual tutor", which can promote the autonomous learning of adult learners in asynchronous online environment. On the other hand, generative artificial intelligence makes it possible for students to receive vocational education in advance. The big model and the massive resource database behind it are accessible and available, and are excellent educational resources to promote the continuous improvement of students’ vocational skills.

  Generative artificial intelligence increases the educational density and improves the efficiency of personalized learning.First of all, in the field of education, the important value of generative artificial intelligence is to create personalized and adaptive learning assistance systems for students, so as to enhance students’ learning experience and high-quality development of educational results. Generative artificial intelligence model has the potential benefits of self-defining educational goals, quickly identifying teaching resources, tracking learning progress and tracking evaluation, etc. It can be used as a digital tutor in the autonomous learning environment of adult learners to make up for the disadvantages of collective teaching organization forms such as class teaching system. The introduction of generative artificial intelligence into teaching is essentially to equip every student with a powerful AI teacher, which may be regarded as a "technical repair" to the traditional teaching environment. Secondly, the multi-modal expression of generative artificial intelligence can make ordinary audience and non-expert audience understand complex scientific concepts, generate cognitive schema intuitively, and keep a deep memory impression. Generative artificial intelligence has the value of making higher education visible, and plays a vital role in popular science education, general education, interdisciplinary education and other fields. Thirdly, generative artificial intelligence gives learners greater autonomy, which can improve students’ subjective initiative and curiosity, and cultivate their problem consciousness and thinking ability to a certain extent.

Moderation: Actively Respond to the Challenges Brought by Generative Artificial Intelligence

  Moderately accept generative artificial intelligence and actively embrace educational modernization.First, based on the initial mission of education, we should moderately accept generative artificial intelligence within the boundaries and promote the complementary advantages of artificial intelligence and natural intelligence. Second, adhere to the principle of using technology in a proper and orderly way, encourage colleges and universities to formulate norms and policies of generative artificial intelligence that meet the needs of their own schools, and clarify the scope, principles and guidelines of educational application of generative artificial intelligence. The third is to optimize the review and evaluation mechanism, do a good job in supervision and prevent the abuse of generative artificial intelligence. Fourth, actively embrace the transformation trend of educational modernization, create a multi-dimensional complementary and virtual-real teaching environment, reasonably embed generative artificial intelligence into classroom teaching, create a more immersive teaching situation by using technologies such as virtual reality, and use technology empowerment to awaken students’ self-cognition.

  Strengthen the digital literacy of teachers and students and make good use of generative artificial intelligence.Digital literacy includes the abilities and skills that individuals need to participate in the complex information ecosystem effectively and responsibly, and also covers the moral dimensions of artificial intelligence use, including data privacy and security, academic integrity and the ability to identify false information. Educators need to constantly improve their digital literacy and take active measures to ensure that students can use generative artificial intelligence tools correctly and appropriately, and deeply understand its potential risks and moral impact, so as to avoid excessive dependence on such technologies.

  Accelerate the cultivation of students’ innovative spirit and creativity, and encourage man-machine co-creation and man-machine mutual strength.Education in the era of artificial intelligence emphasizes openness and creativity, and pays more attention to differences and diversification. Higher education should focus on cultivating students’ innovative spirit and creativity, shift the focus of talent training from traditional ability training to innovative and creative ability training, and advocate cultivating students’ core competitiveness beyond machines. Therefore, firstly, colleges and universities should optimize the curriculum, encourage the development of interdisciplinary courses, develop interdisciplinary cross-learning projects focusing on cultivating innovative consciousness, and cultivate students’ ability to solve complex and practical problems. The second is to reconstruct the teaching evaluation system, from the "result perspective" to the "process perspective" of talent training, to create an inclusive and innovative cultural atmosphere and protect students’ innovative achievements. Third, we should change the concept of educational technology, from worrying about man-machine mutual exclusion to pursuing man-machine co-creation and man-machine mutual strength, and realize the optimal solution of education.

China News ServiceHarbin, April 17th Question: How to break through the differences of "dragon culture" between the East and the West and let the world know more about China?

-Interview with Jin Longshou, the author of The Legend of the Black Dragon

China News ServiceReporter Shi Yifu


"dragon" means auspicious in the East and "Dragon" means evil in the West. What causes this difference? Jin Longshou, the author of The Legend of the Black Dragon, recently accepted an exclusive interview with the East-West Question of China News Service, explaining the historical origin and profound connotation of "dragon culture" and how to break through the differences between the East and the West and tell the fairy tale of "dragon" in China well.

The interview record is summarized as follows:

China News Service reporter: What story does The Legend of the Black Dragon tell? Why does it take ten years to tell this China fairy tale well?

Jin Longshou: Dragon culture runs through the development of the Chinese nation and reflects the spiritual connotation of Chinese culture. The legend of the dragon is spread all over China, and the dragon culture affects the whole of China. In this land of Heilongjiang, the myths and legends of dragons are sung. In order to tell a good story about China, I spent ten years traveling all over Heilongjiang, visiting and researching, collecting materials, and determined to carry forward excellent traditional culture in the form of telling a good story. The Legend of the Black Dragon traces the origin of the name of Heilongjiang, whose predecessor was Bailong River. In mythology, the white dragon often makes waves, so that the countryside is depressed and the people are miserable. Black Dragon witnessed all kinds of evil deeds of White Dragon on earth, and joined forces with Qi Xin, a common people, to rise up and fight back and defeat White Dragon in one fell swoop. Finally, the black dragon showed its original shape as a fairy and dedicated its body to this land. People changed "Bailong River" to "Heilongjiang" to deeply commemorate it.

China News Service reporter: What kind of development has China’s "dragon culture" experienced and what is its relationship with the development of Chinese civilization?

Jin Longshou: Scholars in China have different views on the origin and development of dragon culture. Most of them think that dragon culture has experienced the development process of totem, gods, emperors and other worship consciousness, and many cultural relics and sites have vividly restored dragon culture. China inherits the ancient culture, which is closely related to the development of Chinese civilization in participation, integration, symbol, inheritance and guidance.

"Participation" means that dragon culture participated in the origin of Chinese civilization, and there were dragons in every period in history.

"Integration" means that Long Wenhua witnessed and integrated different ideas in different development periods of Chinese civilization.

"Symbol" means that "dragon" has gradually become an irreplaceable symbol in the development of Chinese civilization. Dragon culture is China culture, and Chinese is the successor of dragon.

"Inheritance" means that the national spirit accumulated for thousands of years has been carried and continued by Long Culture. It is united, harmonious, inclusive, pioneering and innovative, and constantly striving for self-improvement. It has endless centripetal force and cohesion, and always encourages Chinese to struggle hard, be kind and tolerant, persevere and bravely climb the peak.

"Leading" means that in the future, dragon culture will still go higher and further with the Chinese nation. The world outlook of the harmonious development of dragon culture, the national outlook of unity and unity, the values of common prosperity and the world outlook of the community of human destiny will all lead China to achieve common prosperity, long-term stability, prosperity and the great rejuvenation of the Chinese nation.

China News Service reporter: What are the cultural differences between China’s "dragon" and the western "dragon"? What causes such a completely different attitude?

Jin Longshou: loong, which originated from myth, is a mysterious spiritual creature with the body of a snake, scales of a fish and horns of a deer. The Book of Changes says: "In the Ninth Five-Year Plan, the flying dragon was in the sky". The ancients thought that the dragon was the master of the wind and rain, and "the real dragon son of heaven" was the name of the ancient emperor. In the ancient stars, among the four gods guarding the east, west, south and north, Qinglong is a kind of dragon. "Three Graves" says: "The dragon is good at changing, which can cause sex and rain, and it is also for the monarch." The dragon symbolizes good luck and good weather among the people; Wang Anshi’s "Dragon Fu" uses dragons as a metaphor for virtue, which shows that dragons inspire people’s wisdom and morality.

The word "dragon" in English is translated into Chinese as "dragon", but its meaning is totally different from that of loong. The word "dragon" comes from the old French word "dragon", while the latter comes from the Latin word "draconem", which means giant snake. In western culture, people’s first impression of dragons comes from the Bible, which describes a big red dragon, which shows people in an evil image and is the incarnation of Satan. In "Beowulf", Beowulf, the hero, fights with a fire-breathing dragon monster, which continues the evil symbol of the dragon in Christianity. Therefore, the dragon is the object of being slaughtered by heroes in western fairy tales.

In addition, the difference lies in the ideological differences between China and the West. Due to geographical environment and cultural development, western countries tend to demonize and demonize nature or other forces to show and realize individual heroism. In China culture, the emphasis is on collectivism, which is inclusive, benevolent and harmonious. China’s traditional culture teaches us to discover goodness and beauty and be grateful. Therefore, "Dragon" symbolizes the industrious, kind and tolerant world outlook of Chinese children.

China News Service reporter: How is the "Dragon Culture" reflected in China’s social life? With the deepening of cultural exchanges between China and the West, what changes have taken place in the world’s recognition of China’s "dragon culture"?

Jin Longshou: Dragon culture is rooted in China’s excellent traditional culture, which can be described as ubiquitous.

First of all, loong has derived traditional festivals and local customs, such as "Dragon Head Up" on February 2nd, Dragon Boat Race on the Dragon Boat Festival, Dragon Boat Festival for ethnic minorities, and Dragon Sacrifice Festival. Another example is the Chinese zodiac, where only the dragon does not exist in reality and is the sacred mascot of China.

Secondly, dragon totem is also the carrier of dragon culture for thousands of years. No matter how the society develops and the world changes, the dragon totem will always be the symbol of greatness and respect in Chinese’s heart, and the dragon culture is rooted in the heart of every Chinese, which is the fundamental source of pride and responsibility of the Chinese nation. In addition, the "dragon" culture is also vividly reflected in Chinese. For example, there are idioms such as dragon horse spirit, crouching tiger, hidden dragon, dragons and phoenixes are auspicious, and children are eager to succeed. For example, China’s parents often use the word "dragon" when naming their children. The name "dragon" in my brother’s and mine contains parents’ good expectations.

With the in-depth communication between Chinese and western cultures, the understanding of dragon culture in the world is gradually changing. From ignorance to curiosity, foreign friends have now recognized and loved Dragon Culture, which reflects the charm and value of loong culture. This is also due to the spread of loong culture by overseas Chinese, which reflects the patriotic feelings of Chinese sons and daughters and their sense of mission and responsibility as "descendants of the dragon".

China News Service reporter: How to solve the misunderstanding of loong culture in the West?

Jin Longshou: Westerners’ misunderstanding of loong culture stems from the differences in cultural symbols and spiritual connotations. Some experts and scholars put forward that the word "dragon" should be translated into "loong" instead of "Dragon" to reshape the image of loong.

In addition, we should tell the fairy tales of China, especially the fairy tales of dragon culture, publicize the excellent Chinese traditional culture and human history to the world, and let them know and understand Chinese traditional culture.

China News Service reporter: Gu Ailing printed "loong" on her snow suit. What’s the significance of sharing loong culture with the world?

Jin Longshou: In the 2022 Beijing Winter Olympics, Gu Ailing can be said to be the "spokesperson" of loong’s cultural walk. No matter before or after the competition, China delicacies such as steamed stuffed bun, Beijing roast duck, leek box, etc. have aroused public opinion hotspots, and foreign friends are drooling through her introduction, which is a vivid publicity of Chinese food culture. In addition, her costume, snowboard and helmet not only have her own designs of loong, but also English expressions of China Red, Xiangyun and "Dragon among People", which she said is to let the whole world see and understand China culture.

In the arena of the Winter Olympics, she achieved two gold medals and one silver medal, showing Chinese’s qualities of caring for the world, unity and friendship, perseverance, courage and fearlessness, firmness and self-confidence, and courage to climb the peak. She said that she is a bridge between China and the United States, which is an interpretation of loong’s culture, which embraces all rivers, peaceful development and a community of destiny. I hope there will be more "spokespersons" of loong culture like her, and I believe the world will have more objective comments on China. (End)
