[Kehai Tide Watching]

　　In the past few years, a large number of innovative technologies have emerged in the field of artificial intelligence, and key breakthroughs have been made in the fields of autonomous driving, voice and image recognition, medical diagnosis, intellectual competitive sports, etc. Intelligent scenes that people once could only imagine in science fiction movies are quietly coming, and an intelligent era full of infinite possibilities has been fully opened.

　　Artificial intelligence with several ups and downs

　　Artificial intelligence is not a new concept in science. As early as half a century ago, computer science giants represented by Turing, Weiner, McCarthy, Shannon and so on began to explore artificial intelligence scientifically. Turing took the lead in putting forward the basic proposition of artificial intelligence "Can machines think" in his paper "Computing Machines and Intelligence" published in 1950, and designed the famous "Turing Test" — — If a machine can start a dialogue with human beings without being identified as a machine, then the machine is intelligent, which has become the first research to define the standard of artificial intelligence from the scientific level. At the same time, Wiener put forward the famous "cybernetics" and discussed the unity of machine and human — — People or machines accomplish a certain purpose through feedback, which reveals the possibility of simulating people with machines and lays an important foundation for the proposal of artificial intelligence. In 1955, McCarthy, Minsky, Shannon and others, as co-sponsors, invited a group of scholars to discuss Artificial Intelligence at Dartmouth College in the United States, and used the term artificial intelligence, which led to the rise of artificial intelligence scientific research.

　　Although artificial intelligence has always attracted the attention of the scientific community, due to the constraints of basic technical conditions such as computing power, algorithms and data, artificial intelligence technology and commercial development have not been smooth sailing, and even once fell into a trough. Until May, 1997, IBM computer system "Deep Blue" defeated Kasparov, the world champion of chess, which once again triggered global attention to artificial intelligence. Since then, Professor Hilton of the University of Toronto in Canada has made a key breakthrough in the field of artificial intelligence with deep learning as the main technical line. Artificial intelligence has been applied in natural language processing, speech recognition, image recognition, machine translation, fraud detection, product recommendation, etc. In addition, mobile Internet, cloud computing, big data and Internet of Things have matured and formed a technical community effect, providing a technical environment for the technological breakthrough of artificial intelligence. A number of IT giants such as Google, Microsoft, IBM, Facebook, Baidu, Tencent, etc. also foresaw the commercial dawn of artificial intelligence and accelerated the industrial layout of artificial intelligence. In October 2016, the then US President Barack Obama released the report "National Strategic Plan for Artificial Intelligence Research and Development" at the White House Frontier Summit. This strategic plan, known as the new "Apollo Moon Landing Plan" in the United States, marked the US government’s emphasis on artificial intelligence, and artificial intelligence has reached a turning point of breakthrough.

　　According to the development stage and level of artificial intelligence, some foreign experts divide artificial intelligence into three stages: Artificial Narrow Intelligence (ANI), Artificial General Intelligence (AGI) and Artificial Super Intelligence (ASI). Weak artificial intelligence is good at unilateral ability, such as only having the intelligence to play chess. Strong artificial intelligence refers to artificial intelligence that has the same cognitive ability as human beings in all aspects; Super artificial intelligence refers to surpassing the limits of human intelligence in all fields. Generally speaking, human artificial intelligence is still in the stage of weak artificial intelligence moving towards strong artificial intelligence.

　　Cutting-edge technology that subverts the future

　　As a subversive technology with "singularity" characteristics, artificial intelligence can not only drive a new round of scientific and technological innovation and economic growth, but also overcome a series of development difficulties faced by human beings in the fields of transportation, environment and health care, thus creating a new paradigm for global economic and social development.

　　In 2016, Accenture, a famous consulting firm, released a report saying that artificial intelligence will become the driving force for a new round of global economic growth. By 2035, by changing job attributes and creating new man-machine relationship, artificial intelligence will double the economic growth rate, and the problems that have plagued the world economy for a long time, such as production stagnation, resource mismatch and labor shortage, will be solved, and people will be able to get out of "inefficient" work and do truly efficient and creative work.

　　Intelligent transportation and unmanned driving are the key areas of artificial intelligence development at present. In the future, the transportation facilities with artificial intelligence application will not only include passenger cars, but also trucks, aircraft and personal robots. Automated transportation will be everywhere, and cars will become better drivers than humans. Intelligent transportation systems will effectively overcome urban traffic jams and parking difficulties, reduce the incidence of car accidents and reduce automobile emissions, and there will be fewer private cars for urban residents, thus changing the overall appearance of the city and bringing a brand-new form of urban organization.

　　Artificial intelligence will also make great achievements in the medical field, which will help mankind overcome a series of medical problems to a great extent and solve the problem of uneven distribution of medical resources. Take IBM Watson as an example. An expert from the Medical College of the University of North Carolina in the United States asked Watson to analyze and diagnose more than 1,000 cancer cases. It was found that Watson gave the same treatment plan as a human oncologist in more than 99% of the cases. A Tokyo woman with leukemia was sentenced to death by a doctor, but Watson read the relevant 4,000-meter-thick medical materials within 10 minutes and gave a treatment plan to save her. Recently, a teenager in Britain underwent medical surgery based on artificial intelligence technology and got rid of epilepsy for seven years. The doctor asked the robot to drill into his brain, stimulated the cerebral cortex through electrodes, and found out the part that caused the seizure. The doctor removed the lesion.

　　An out-of-control problem of no trial and error

　　When artificial intelligence technology continues to reshape people’s work, study and lifestyle, and brings infinite happiness to mankind, it is also generating more and more open problems.

　　1. Artificial intelligence is out of control. It is an ancient and ultimate problem of artificial intelligence whether it can keep control of an artificial intelligence system that is far smarter than human beings one day. The problem of control and out-of-control is so important because human beings may not have the opportunity to try and make mistakes at all. Although it is generally believed that the existing artificial intelligence technology is still in the stage of weak artificial intelligence, many experts believe that the era of super artificial intelligence is not far away, and the form of super artificial intelligence can realize recursive self-improvement and lead to the final "intelligent explosion". In 2008, a survey of experts at the Global Catastrophic Risk Conference held in Oxford University showed that machine super-intelligence has surpassed nuclear war, various manipulated epidemics and climate change to become the greatest threat to mankind. By 2100, the possibility of this artificial intelligence leading to human extinction is 5%. In this regard, the author of "A Brief History of the Future" and Israeli historian Herali pointed out three possible directions for human beings: human beings will lose their economic and military uses, and the economic system will no longer be valuable; For the system, human beings as a whole will have value but individuals will have no value; However, the system will find value in some individuals, but they will become a new species of superman, not the general public. "System" refers to a new social form produced by the rapid development of biological science and information technology.

　　2. Machine discrimination. In the Internet of Everything environment, artificial intelligence systems based on massive data and powerful algorithms are influencing or even replacing individual behavior decisions. Under the trend of artificial intelligence replacing individual decisions, algorithm deviation and machine discrimination are not uncommon and have great influence. For example, Google’s photo software has wrongly labeled black people as "gorillas", and Flickr’s automatic tagging system has also wrongly labeled black people’s photos as "apes" or "animals". The problem of Google’s algorithmic discrimination has attracted people’s attention. In Google search, it is easier to find advertisements implying a criminal history than searching for white people’s names. In Google’s advertising service, men see more high-paying job advertisements than women.

　　3. Skilled unemployment. Technical unemployment is also a major challenge arising from the development of artificial intelligence. Kaplan, a professor of artificial intelligence and ethics at Stanford University, believes that the most important challenge for human beings to deal with artificial intelligence lies in the change of labor force and the distribution of wealth in the whole society, which has an impact on the stability of the existing society. Schwab, chairman of the World Economic Forum, also pointed out that the wide application of high technology in computer-controlled, fully automated and networked production and service industries, such as the use of robots, may lead to the loss of a large number of jobs in the future.

　　4. Human-machine emotional ethics. The development of artificial intelligence technology will lead to the subversion of traditional human ethics. In the autumn of 2015, the British BBC and CNBC reported that an American company had created a female image "sex robot", and the person in charge of the company believed that the product could help the widowed solve their life troubles. It is reported that the robot presupposes a variety of personality patterns, such as "communicative" and "obedient", but the product has aroused extensive ethical discussion.

　　As Hassabis, the founder of DeepMind, said: "Artificial intelligence is a great technology. It is neutral in itself and may be used in good places or bad places, so we must ensure that its users are responsible." In this regard, the United States, Britain, Japan, as well as the United Nations, the European Union, IEEE and other international organizations have issued strategies, laws, standards and norms of artificial intelligence, hoping to promote the healthy development of artificial intelligence technology and industry through the guidance of artificial intelligence policies and ethics. We should scientifically regulate artificial intelligence from laws and regulations, social security, technical standards and application norms, so as to promote the healthy development of artificial intelligence technology and industry and prepare for the future of artificial intelligence.

　　8月8日是我国第14个“全民健身日”。党的十八大以来，以习近平同志为核心的党中央大力推动体育事业改革发展，将全民健身上升为国家战略，推动全民健身和全民健康深度融合。

　　What are the people’s sense of gain and happiness, and what are their expectations and wishes for national fitness? Please follow the reporters from all over the world to find the answer in this picture of the times of "I exercise, I am happy".

　　[Reporter’s observation]

　　Follow the "National Fitness Road" and run towards health and happiness.

　　Guangming Daily reporter Zhang Sheng Gao Jianjin Ren Shuang Su Yan

　　A basketball court full of people, a vibrant square and a fitness trail suitable for all ages … … To feel the pulse and vitality of a city, we must look at these "steaming" fitness places.

　　Nowadays, the constantly upgraded national fitness facilities and the prosperous mass sports events have made more and more people move and laugh, making their lives more interesting and steaming.

　　"15-minute fitness circle" measures the happiness radius of the people

　　In the early morning of August 3rd, the semi-final of "beautiful countryside" basketball league in Taipan Village, Taijiang County, Guizhou Province came to an end. In Qiandongnan, Guizhou Province, the basketball game has become the most lively activity in the "Eating New Festival" of the Miao people on the sixth day of the sixth lunar month. The basketball league, called "Village BA" by netizens, has played an international role, relying on Guizhou’s practical measures to implement the national fitness strategy for many years and fully promote the construction of the "six sides" project of national fitness.

　　In Fuzhou, Fujian, the theme demonstration activity of "National Fitness Day" in 2022 — — "Wan Li Fudaojian Walking, a provincial walker" is under intense preparation. Ye Desheng, Party Secretary and Director of Fujian Provincial Sports Bureau, who was busy at the scene, told reporters that Fujian actively promoted the construction of sports parks and fitness trails. Up to now, there are 8,891.52 kilometers of various fitness "Fudao" in the province, which greatly improved the happiness index of the people.

　　In order to solve the problem of fitness "venue", the central government has continuously improved the system design, and local governments have continuously accelerated practical exploration. Guided by the Opinions on Strengthening the Construction of National Fitness Facilities and Developing Mass Sports issued by the State Council and the Opinions on Building a Higher Level Public Service System for National Fitness issued by the State Council of China, in the process of urban renewal and rural revitalization, "15-minute fitness circles" have been continuously built all over urban and rural areas, extending the "last meter" of serving the mass fitness to the doorstep of the people.

　　From "Walking around the Ridge" to "Walking along the Waterfront Greenway", the bustling crowd danced to the music on the Little Square in the center of Lianhua Town, Jiande, Zhejiang Province.

　　In Changchun, Jilin, citizen Cai Dongting is taking the whole family to do outdoor sports. The Yitong River, which used to stink at home, has become clear and sparkling, with riverside parks springing up and fitness trails slowly spreading along the river. "Everyone looks at the beautiful scenery along the river and no longer has to worry about where to exercise." Cai Dongting told reporters while jogging.

　　Looking at the land of China, there are "Frisbee fever", "Marathon fever" and "Bike fever" in urban blocks, and the heat flow of stocks marks the temperature range of national fitness; On the vast fields, "people’s gyms" have opened their doors to meet the fitness needs of farmers.

　　"In recent years, the construction of fitness facilities has been intensified from the central finance to local finance." Zou Xinxian, director of the Teaching and Research Section of Public Administration of Beijing Sport University and chief expert on the development of Beijing Winter Olympics culture and ice and snow sports, believes that since the 18th National Congress of the Communist Party of China, the national strategy of national fitness has been implemented in depth, and the contradiction between the supply of public services for national fitness and the growing demand of the people has been shrinking, the venues and facilities have been significantly improved, and the participation of national fitness has been continuously improved.

　　"Fitness Menu" and "Exercise Prescription" to stimulate the enthusiasm of the masses for sports

　　More than 90 days after it was launched, more than 100 events were launched, with more than 11.6 million direct participants … … Since its launch on April 28th this year, the National Fitness Online Games has handed over a bright report card. It is understood that the "Sports Meeting" has carried out more than 100 events such as shuttlecock, skipping rope, curling and chess and cards, and has sent a rich "fitness menu" to the masses.

　　These days, Henan guy Wu Chenguang felt in the WeChat circle of friends: "‘ Clouds go to Qilu ’ Although it is over, I still want to continue to exercise and meet the most beautiful scenery in life with every solid step. " What he mentioned is the third "Cloud Walking Qilu" online ten thousand people walking. There were 584,000 people who signed up for the event, 11,000 teams were formed, the total number of punching kilometers was nearly 20.93 million kilometers, and the punching rate was over 63,000. In addition to Shandong, this national fitness event also attracted people from 25 provinces, autonomous regions and municipalities including Liaoning, Chongqing and Beijing.

　　After the Tokyo Olympic Games, many China athletes who returned from the games became star coaches to guide mass fitness on the Internet, attracting many young netizens. For example, Zhang Yufei, a famous swimmer in China and a champion of the Tokyo Olympic Games, successfully "went out of the circle" and became a "private education for all", bringing everyone a physical fitness class full of dry goods.

　　On the one hand, online sports are unprecedentedly popular, on the other hand, the coverage rate of offline national fitness facilities is constantly improving, and various mass events are blooming. The fiery practice in real life and the magnifying effect of cyberspace make the "big garden" of national fitness more colorful.

　　In this "big garden", such a group of people are still active — — More than 2.7 million social sports instructors make physical fitness "guided". "They have become an important force in promoting national fitness." Gu Xiaohua, a national first-class social sports instructor and director of Suzhou Social Sports Instructors Association, was deeply touched: "Today, there are more than 39,700 social sports instructors at all levels in the city, with 44 per 10,000 people. Many citizens are driven by their enthusiasm and professionalism and join the national fitness team."

　　The reporter learned that in order to provide more scientific "exercise prescriptions" for the people, the State Sports General Administration, together with the National Health and Wellness Commission and the Ministry of Science and Technology, and other relevant scientific research units, launched a number of popular science works, developed a number of fitness methods, and organized athletes from national teams and provincial teams to enter primary and secondary schools and communities to carry out fitness guidance services, so as to promote the sharing of competitive sports achievements among the whole people.

　　Advocate the concept of age-old friendship and join hands in running towards a healthy China.

　　On a hot summer day, on the campus of Wangjiang Road, Daoxiang Village Primary School, Shushan District, Hefei City, Anhui Province, coaches such as roller skating, football and table tennis gathered together. The small players sweated like rain, and the summer training was very lively. "At present, the school has obtained technical support and venue support from all walks of life, and more than 1,000 students in the school have richer and more convenient choices for extracurricular activities." Xue Hong, Executive President of Wangjiang Road Campus of Daoxiang Village Primary Education Group, introduced.

　　For Chen Huilai, a Fujian walker, walking is economical, safe and suitable for all ages. Since she joined the walking team of the old sports association in 2019, she has been walking for 8 to 10 kilometers every day and organized team walking training.

　　Jia Junting Xian, 36, suffered from congenital eye disease, which led to blindness. Sports became her first track to realize her self-worth. In September 2016, she won the gold medal in the women’s T11-T13 4× 100m relay event at the Paralympic Games in Rio de Janeiro. She retired the following year and returned to her hometown as a special education teacher. "I have been helped by many people since I was a child. I want to pass on these loves and let more disabled friends feel the sunshine and warmth in sports." She said.

　　Over the past few days, the cultural auditorium of Daijia Village, Lianhua Town, Jiande, Hangzhou has been very lively. More than 60 martial arts fans from all over the province are conducting a Tai Chi tuishou referee training and skill test. "To inherit Wushu culture, we must understand the essence of emphasizing morality, ceremony and harmony behind it." Deng Linlin, the chairman of jiande city Wushu Association and the "literary village head" of Lianhua Town, believes that more people should know and learn Wushu to further enrich people’s spiritual and cultural life … …

　　In recent years, all localities have explored the creation of a brand featuring farmers’ culture and sports with "one product in one place, one item in one village", developed sports with agricultural characteristics suitable for different groups of people and different regional characteristics, and promoted traditional Chinese sports such as martial arts, dragon boat and health qigong, thus injecting vitality into rural revitalization.

　　如今，全民健身还与经济、民生、教育、文化等事业同频共振、相互交织，共同托举起百姓幸福美好的生活。“共同富裕路上，要继续倡导全龄友好理念，着力保障老年人、残疾人等弱势群体的运动权益，让全民健身成为一种普遍的生活方式。”清华大学体育产业发展研究中心主任王雪莉表示。

　　【专家点评】

　　大健康理念下 全民健身蔚然成风

　　作者：解植岗（北京市习近平新时代中国特色社会主义思想研究中心特约研究员、北京体育大学新闻中心主任）

　　党的十八大以来，以习近平同志为核心的党中央把满足人民健身需求、促进人的全面发展作为体育工作的出发点和落脚点，将全民健身上升为国家战略，推动全民健身和全民健康深度融合。10年间，全民健身场地设施明显改善，群众性体育赛事繁荣发展，全民健身参与程度不断提高，人们的生活方式更加文明健康，“体育让生活更美好”已成为火热现实。

　　Standing at the historical intersection of the goal of "two hundred years", national fitness presents new characteristics of the times.

　　First, the two national strategies of national fitness and healthy China are closely linked and deeply integrated. The concept of "sports is a good doctor" is deeply rooted in the hearts of the people, and the integration of sports and health and sports and tourism is gradually deepening. People have changed from "asking me to exercise" to "I want to exercise", and active fitness and scientific fitness are gradually integrated into daily life. By the end of 2021, the proportion of people who regularly participate in physical exercise reached 37.2%. Second, the card points that focus on the people’s fitness needs block the pain points, and the "hardware" and "software" shortcomings are quickly filled. By the end of 2021, there were 3.971 million sports venues in China, with an area of 3.41 billion square meters, with a per capita sports venue area of 2.41 square meters, up by 134.3%, 71.2% and 65.1% respectively compared with 2013. Idle "marginal areas" in cities have been transformed into good places for daily exercise, and more sports venues are open to the society free of charge or at low fees. In terms of the coverage of fitness programs, a large number of activities to facilitate the people, benefit the people and benefit the people have appeared around the people, and sports such as ice and snow, which were strongly influenced by the region in the past, have achieved leap-forward development. Third, the new technology empowers the whole people to keep fit. With the blessing of 5G technology, cloud live broadcast and short video are developing rapidly. The fashionable sports equipment and software platforms are making the threshold of sports lower and lower and getting closer to people’s lives.

　　Sports is not only the proper meaning of a strong country, but also the foundation of a happy life for individuals. It is not only an important driving force to promote economic and social development, but also a platform window to show the soft power of the country’s culture. On the new journey, to continue to promote the in-depth development of national fitness, we must better understand the value and significance of national fitness — — For individuals, fitness is the most affordable health investment; In society, national fitness is the most inclusive public service; In the country, national fitness can improve the health level of the whole nation, promote the progress of social civilization and promote the all-round development of people.

　　Looking at the whole country, the vigorous national fitness campaign not only allows the people to gain a healthier body and mind, but also becomes a good prescription for people to boost their spirits; The happiness, self-confidence and openness brought by sports contain majestic positive energy and inject new spiritual vitality and development momentum into national rejuvenation.

　　On the road to common prosperity, we must firmly establish the concept of great sports and great health, improve the health literacy of the whole people, and continue to promote the deep integration of national fitness and national health with pragmatic measures. We believe that with the joint efforts of all parties, national fitness will become a common practice and become a popular social trend.

　　[First-line narration]

　　Climb and feel the beauty of mountains and rivers.

　　Narrator: Wang Yong, President of Ningxia Yinchuan Hiking Association

　　"Ningxia chuan, two-headed. East by the Yellow River and west by Helan Mountain. " Like many mountain climbers and hikers, we like to use high mountains and rivers as natural gymnasiums. Just a few days ago, at the National Mass Fitness Mountaineering Conference and the first Helan Mountain National Mountaineering Competition, mountaineering enthusiasts from all over the world gathered in Yinchuan and headed for the mountains and rivers.

　　In 2013, my friends and I founded the Yinchuan Hiking Association, and its members have grown from dozens to more than 25,000 today. In recent years, the government has taken the lead in holding a series of activities, such as the National Mass Fitness Mountaineering Conference, the "I want to go" National Walking Linkage Day, and the Helan Mountain Starry Camping Conference, with the active participation of the Association.

　　In response to the call of national fitness, the association also organized the theme hiking activities of "Bonfire Great Wall" and "My Yellow River", and planned to walk all the routes of the Great Wall and Ningxia section of the Yellow River in two years. The association also actively participates in the ecological protection along the Great Wall and the Yellow River, and encourages everyone to pick up the left-behind garbage in mountaineering and hiking by exchanging points for gifts and vouchers to jointly protect the beautiful environment.

　　Next, we plan to launch 40 series of hiking activities, "Discover the beauty of Ningxia" and "Me and my hometown", to let more people know about Ningxia, a good place.

　　[First-line narration]

　　Keep fit and keep in good shape.

　　Narrator: Wang Jing, a network fitness expert

　　The reason why I participated in online fitness teaching is not only because I majored in physical education in college, but also because I have rich working experience. From fitness coach, sports course designer, coach trainer to being a training director in a fitness institution, these experiences contain my unchanging original intention — — Let more people have good posture and posture.

　　After the Spring Festival in 2019, I began to share videos of exercise and fitness online. Unexpectedly, it took only three months to make a lot of explosions. Later, when the COVID-19 epidemic struck, I made a lot of exercise videos that I could train at home, and the response was good. Some fans left messages suggesting that I broadcast live. Now, just turn on my mobile phone and you can find me — — Everyone’s "personal education". I also set up a fitness class online and set up a fat-reducing and shaping camp to get more people moving.

　　Thanks to this good era, let’s plug in the wings of the Internet and ride against the wind, so that more people can benefit from the scientific movement for life.

　　message board

　　In recent years, in order to make the old people in the village have fun, we have built a gateball court. In order to attract the elderly to participate, we organize teams to play games and raise funds to buy sports equipment for the elderly. Due to the low threshold of playing gateball, the enthusiasm of the old people to participate is getting higher and higher. Nowadays, the old people gather at the gateball court as soon as they have time, playing ball and chatting, which is very popular. A small gateball made the old people move and be happy.

　　— — Yan Ju, Director of Security Protection in Xianfeng Village, Xiaogushan Town, Yitong Manchu Autonomous County, Jilin Province

　　Our school is located in the suburban industrial zone, parents are busy with their work, and many students have become "chubby" under the love of grandparents. Since the implementation of the "double reduction" policy for one year, the school has arranged various forms of inter-class exercises, such as table tennis exercises and fancy rope skipping. P.E. teachers set up interest classes after class and take the children to practice basketball and badminton. This summer, many children teamed up to play football at school, and the campus in summer was full of laughter. Teachers and parents are happy to see the "chubby piers" become vigorous.

　　— — Wang Gongqin, Vice President of Longtang School in Feidong County, Anhui Province

　　After retirement, I passed the exam and became a social sports instructor, teaching Tai Ji Chuan and Qigong in parks and squares every Monday and Wednesday. Unexpectedly, many young people are also actively involved. Now, in parks, squares and under city walls, the figure of mass exercise can be seen everywhere. I am really happy to see more and more people moving.

　　— — Gu Xiaohua, national first-class social sports instructor and director of Suzhou Social Sports Instructors Association, Jiangsu Province.

　　I often walk along the trail built by the mountain. Walking through the mountains, there are both slow roads and landscapes, and "China under the toe" is so beautiful that people are relaxed and happy. This year, I participated in the "National Fitness Walking with the Winter Olympics" held in Gushan, the New Year’s Climbing Walk, and the 10,000-person Walking Walk held in Feifeng Mountain. Every weekend, I also organized cross-country hiking in the surrounding Shan Ye, which not only strengthened my physique, but also made me feel the beauty of mountains and rivers.

　　CCTV News (World Weekly):How many children went to the circus on Children’s Day? Circus performance is one of the good memories of childhood for many people. Today, in some large theme parks, the most popular performance is circus. But on May 21st, a 146-year-old "Lingling Circus", known as "the greatest performance on earth" and one of the three largest circuses in the world, held its final curtain call in new york and announced its closure. The news made many people feel particularly sad, but it also made others jump for joy. What does the closure of Lingling Circus mean?

　　　Wonderful performance bid farewell to "the greatest performance on earth"

　　On May 21st, the farewell performance of Lingling Circus was held in Nassau Veterans Memorial Gymnasium in Long Island, new york, USA.

　　Before the performance, Kenneth Field, CEO of the American Field Entertainment Company, the parent company of Lingling Circus, gave a speech in the center of the stage.

　　After a tense 10-second countdown, the performance officially began.

　　The whole performance lasted for 2 hours and 30 minutes, which was wonderful and won applause from the audience.

　　After this final performance, the 146-year history of Lingling Circus came to an end.

　　Audience: It was very interesting. The performance was fantastic, but it was very sad. My children just cried and asked me, Mom, why is the circus closed? Today, I brought my mother, aunt and friends to watch the performance. It was a little sad, but I was glad that we could come. I saw their circus when I was a child.

　　Audience: Unfortunately, the circus has become a symbol of American culture.

　　Past lives of Lingling Circus

　

　　The history of Lingling Circus can be traced back to 1871.

　　At that time, Phineas Taylor Barnum, an American, organized a circus performance by showing rare animals and people with strange shapes, which was very popular with the audience.

　　Ten years later, barnum cooperated with his main competitor, james bailey, and established "barnum and Bailey Circus", the predecessor of Lingling Circus.

　　After barnum and Bailey died, another "Lingling Brothers Circus" formed by five brothers from Wisconsin bought "barnum and Bailey Circus" and merged into "Lingling Circus".

　　At the beginning of the 20th century, Lingling Circus began to change its style. Instead of taking animal exhibitions as its selling point, it trained animals to perform with circus actors, among which elephant training became the signature program of Lingling Circus.

　　In 1967, Lingling Circus was bought by the Field family. The circus continues to expand, hiring a large number of employees and paying a lot of money to collect the world’s rare animals. Every year, Lingling Circus will tour more than 100 cities and become an important part of American entertainment culture. Together with two rising stars: new york Big Apple Circus and Cirque du Soleil, it is known as the three largest circuses in the world.

　　The golden age of circus performance is fading away.

　　However, with the rise of film and television entertainment, electronic games and the Internet, the golden age of circus performance is gradually fading away.

　　Due to high operating costs and declining ticket sales, many circuses have closed down in recent years.

　　In November 2016, the 39-year-old new york Big Apple Circus declared bankruptcy and auctioned its assets in January this year.

　　Jonathan Iverson, head of Lingling Circus: It’s a pity that today’s society no longer pursues miracles that can’t be seen on the Internet.

　　In addition to the pressure of operation, the criticism from public opinion has also put the circus featuring animal performances in an awkward position.

　　Double pressure of management and public opinion crushed Lingling Circus.

　　Members of animal protection organizations: They mistreat animals.

　　Audience: Never mind? ? They won’t do that.

　　Members of animal protection organizations: They abuse animals with tools.

　　Audience: Have you really seen these behaviors you are talking about?

　　In the eyes of animal protection organizations, circus is the hardest hit area of animal abuse.

　　Because most performing animals will be forcibly taken away from their parents after birth. In the process of training, animal trainers will use various ways to destroy their will.

　　Elephant performance was once a classic performance of Lingling Circus.

　　The elephants on the stage look docile and clever, but their growth process is full of fear and helplessness.

　　He was separated from his parents at an early age and received human training. During the training process, the animal trainer will tie up the limbs of the elephant with ropes. Once the elephant’s performance fails to meet the requirements, the animal trainer will stab their sensitive parts with the hook stick in his hand, forcing the elephant to obey because of fear, and finally achieve the goal of domestication.

　　Even if they are trained successfully and become star actors, the situation of these animals is equally pitiful.

　　Because most circuses use the way of touring performances and travel all the year round, the train has become the home of circus members. They married with children, living on the train, look romantic. But animals are different. On endless roads, they are always chained by cold chains and live in narrow carriages.

　　In 2011, for violating the Animal Welfare Law, Field Entertainment paid a fine of US$ 270,000, or about RMB 1.86 million, to the US Department of Agriculture.

　　However, Field Entertainment does not admit that it has abused animals.

　　Their attitude made animal protection organizations increase their protests against the circus.

　　Every time Lingling Circus holds a performance, members of animal protection organizations can be seen outside the venue. They seriously discourage the audience who come to watch the performance.

　　Members of animal protection organizations: Now they will go in and watch the performance without looking back, and when they realize the seriousness, they will stand on our side.

　　Member of animal protection organization: If you don’t want your children to be treated like this, why do you have the heart to let other people’s children suffer from this?

　　Under the pressure of public opinion, finally, in May 2016, after completing the last elephant performance, Field Entertainment decided to retire the elephants in the group and send them to the Florida Animal Protection Center.

　　Without the elephant in the town, the circus ticket revenue "dropped sharply".

　　In January this year, Lingling Circus announced that it would be completely closed at the end of May due to high operating costs and declining ticket sales. After the closure, all the animals in the group will be sent to other suitable places, but the company did not disclose the specific place.

　　Field, CEO of Field Entertainment, USA: Circus has experienced world wars, every economic cycle and many changes. People don’t like circus as much as they used to.

　　Circus should also keep pace with the times. Cirque du Soleil’s "O" show relies on technology instead of animals.

　　Today, among the three major circuses in the world, the only one left is Cirque du Soleil from Canada.

　　This circus, founded in 1984, found a new way, not relying on animal performances to attract attention, but relying on high-tech dance design to gather the world’s best acrobats and gymnasts, coupled with a Hollywood blockbuster-like plot, to present a gripping performance, which soon became a great success and has received rave reviews so far.

　　"Thirty years ago, a circus without animal performances would be regarded as deceiving the audience, but now people like a different circus."

　　-Denver Post

　　Conclusion: More humane, safer, more environmentally friendly and healthier entertainment.

　　Some people say that the closure of Lingling Circus marks the decline of this traditional form of entertainment.

　　However, many people are still optimistic about the future of circus, thinking that circus performance is also advancing with the times, seeking changes in form and content.

　　Indeed, with the change of social concepts and the development of scientific and technological means, people’s entertainment methods have been constantly updated. What we expect is that the mainstream development direction will become more humane, safer, more environmentally friendly and healthier.

　　The agency pointed out that the release of Mate60 series last year was regarded as the first shot for Huawei to return to the mobile phone market; Looking forward to April, the release of Huawei P70 series is highly anticipated. Huawei P70 will be released soon, and related innovations are expected to drive a new round of opportunities in the mobile phone industry chain.

　　Since the "return" of Huawei mobile phone last year, it has made great strides. Counterpoint data shows that Huawei’s mobile phone sales soared by 64% in the first six weeks of this year, and its ranking also rose to the second place, leaving only 1 percentage point behind the number one vivo. As for the growth of Huawei’s sales, some media reported that at present, more growth still comes from Huawei’s Mate60 series. Although the price increase in the secondary market has basically leveled off, there are still some versions that can increase their prices. 5. 600 yuan. As for the newly released Nova, it has also played a certain role. With the help of the mid-end market, it will further promote the rapid growth of Huawei’s mobile phone sales.Zou Lanlan believes that the return of Huawei is expected to reshape the competitive pattern of the domestic mid-to-high-end mobile phone market and promote the industry to regain its vitality.

　　According to the theme library of Cailian, among the relevant listed companies:

　　The downstream products of the application are mainly touch module manufacturers, and the coverage of well-known terminal customers is achieved through well-known touch module manufacturers. The terminal brands include Huawei, Xiaomi, VIVO, OPPO and so on.

　　Paint products are mainly used in terminal brands such as HUAWEI, OPPO, 1+, Realme, Coolpad, Lenovo, Samsung, Motorola, Hisense, Voice and TCL.

Carrying out "reading for all" activities throughout the country is an important measure to build a learning society and an indispensable cultural construction to realize the great Chinese dream. Since the nationwide reading activity was launched, it has received enthusiastic response from all walks of life and achieved remarkable results.

Why should we advocate reading for all? In short, reading can cure fools and improve intelligence; Long knowledge and broad thinking; Learn skills and increase your skills; Enrich one’s thoughts and cultivate one’s sentiments. One person benefits from reading; Read for all and benefit all. In a word: opening books is beneficial. For individuals, reading can improve their quality and change their destiny; For the nation, reading can inherit civilization and spread science. Therefore, Confucius never let go of the book all his life, and in his seventies, he still "read the Book of Changes and compiled three unique works by Wei"; Gorky "threw himself at the book, just like a hungry man threw himself at the bread". Zheng Chenggong sincerely felt that "cultivating the heart is nothing more than wanting, and the joy is nothing more than reading"; Ji Xianlin sincerely praised "reading is the best thing in the world". They all turned reading into a necessity of life, and enjoyed it tirelessly, so they benefited greatly and benefited for life. They come from different ages and engage in different occupations, which can be regarded as a microcosm of national reading.

Reading for all evolved from "World Reading Day". The purpose of setting up reading day is to call on everyone in the whole society to read, so that books can become a necessity and reading can become a part of life. Therefore, every year on World Reading Day, we will sum up our experience, discuss our gains and losses, and put forward improvement measures to make the reading activities for the whole people more solid and effective.

Reading for the whole people depends on persistence and long-term success. Marx studied hard all his life, and regarded reading as his life. No matter how poor and difficult his life was, he never forgot to study, often forgot to eat and sleep, day and night, and finally slept on his desk. Mao Zedong studied tirelessly since he was a teenager, read widely and loved reading all his life. He was still studying a few hours before his death. They are all models who insist on reading, which makes people stop at the mountains. Unfortunately, some of us spend three days fishing and two days drying the net, reading a few pages when we are happy, and putting them on the shelf when we are depressed; Turn over a few articles in your spare time, and forget about it when you are busy with your work. Such a reading attitude, in a spirit, exposed to ten cold, it is difficult to gain something. In view of this, we should also persevere in reading, and the long running water will not stop, and over time, water drops and stones will wear out before we can read out the benefits and effects.

全民阅读，领导干部应成为带头读书的楷模。榜样的力量是无穷的。习近平总书记夙夜在公，仍挤出时间坚持读书学习，在谈到自己的爱好时说：“现在，我经常能做到的是读书，读书已成了我的一种生活方式。”正是因为长期孜孜不倦地读书学习，锻炼了他非凡的领导才能和卓越的政治智慧，成为当今中国走向伟大民族复兴的卓越领路人。

全民阅读，要加强引导，让大家多读好书，多读经典。所谓好书，一是具有思想性、艺术性、可读性；二是经得起时间检验，能够传世；三是被评论家广泛认可，拥有大量读者。若按这三个标准衡量，好书与古今中外那些经典书最为接近。人生如白驹过隙，书籍却浩如烟海。为提高生命的知识含量和学习效率， 就一定要多读经典，以便在有限时间获取更有价值的知识。多读经典，于个人可以广见识、明事理、受熏陶，善莫大焉；对社会而言，则可教化民众，端正风气，提高全民族精神文明素质，对于我们正在打造的书香社会更是功德无量。

Reading by the whole people should keep pace with the times in various ways. It can be either a flat paper book reading or an e-book reading; You can read on the computer network or on the mobile phone WeChat. It can be a big time to concentrate on studying, or it can be a casual browsing of leftover materials; It can be the sound of books in the classroom, or it can be "immediately, on the pillow, on the toilet" when you are busy. In short, it’s not stick to one pattern, it’s good to read it, and it’s beneficial to read it

Reading for all makes reading a common practice. Taking reading as a way of life is not only a rational and conscious choice, but also a need to adapt to the objective situation. Reading can be a subjective hobby, because if you are interested, you will feel happy, such as drinking good wine and soaking in the spring breeze. At the same time, you can cultivate your sentiment, open your mind, improve your consciousness and broaden your knowledge. Reading is also an objective need, which can acquire knowledge, learn skills, increase talents and broaden ideas, so as to be competent for the work, keep up with the situation, meet challenges calmly and be invincible in the fierce competition.

Public Network reporter Mao Daoguang reports from Qingdao

The past weekend has become the most unforgettable day for Qingdao football!

In the 29th round of League A, Qingdao West Coast, which holds the initiative, beat Guangzhou team 2-0, thus locking the Super League seat in advance for next season. At this point, there are two Super League teams for the first time in the history of Qingdao football, and it has become the seventh city in China that will soon have the "Super League Derby" after Shanghai and Guangzhou.

Success is never achieved overnight. In the past ten years, Qingdao professional football has set foot on the top of the mountain and once fell into a trough. Fortunately, Qingdao football has never given up lightly, and with a tenacity, it has regained the road of chasing dreams in difficulties.

One city "double super"! At this moment, Qingdao football has realized the "dream of two heroes" in the top leagues in China, and let the whole country see the profound connotation of "Football City" and let football become the shining business card of this city again!

01

Looking back at Qingdao football in recent years, there are too many moments worth remembering!

Drinking ice for 9 years, blood is hard to cool! After many years of silence, Qingdao Manatee returned to the Super League from China B, and made its home debut 10 years later in Youth Stadium, the first 50,000 professional football stadium newly opened in Shandong this season, beating former enemy Beijing Guoan 3-1, which made countless fans dream back to 10 years ago and rekindled the hope of Qingdao football.

Qingdao West Coast Football Club, formerly known as Qingdao Kangtaiyuan Commercial Concrete Football Team, was established in 2007. In 2019, it was awarded the qualification of Grade B, and officially entered the China Football Professional League in 2020. In April, 2022, Qingdao Youth Island Football Club officially moved into German Football Asia Base. After playing in League A in the 2022 season, the young team hit it off with the West Coast, a city of youth, and set a more ambitious goal: changing its name to the West Coast, fighting for Qingdao and fighting for the West Coast New District.

The home relocation to Qingdao West Coast University Town Stadium marks that Qingdao West Coast New District has the first team to compete in professional football matches. As a new landmark of the West Coast New District, Guzhenkou University Town Stadium can accommodate 20,000 people and is one of the closest stadiums in China. It has been officially unveiled and put into use on May 10th this year. As the home of Qingdao West Coast Team in League A and Qingdao Red Lion Team in League B, it has been frequently unveiled in national competitions.

This autumn, Qingdao Manatee relegated to the Super League two rounds ahead of schedule, Qingdao West Coast overtook the Super League one round ahead of schedule, and Qingdao women’s football team returned to the domestic women’s football professional league, all of which are inseparable from the silent cultivation of Qingdao football for many years. With the end of the "Jinyuan Football" era, the inherent advantages of Qingdao football have gradually emerged, and the achievements of football development and youth training have blossomed everywhere, which has also polished the "golden signboard" of football again.

"The success of the West Coast Club is inseparable from the attention of the municipal party committee and the municipal government and the support from all walks of life. With two super league teams, Qingdao football has reached a new height. I hope that we can make persistent efforts next, and Qingdao Football can continue to contribute to China Football. " Tian Weiguo, director of Qingdao Football Activity Management Center, said this.

As a prestigious "Football City", on January 25th, 2022, Qingdao was successfully selected as one of the first nine key cities for football development in China during the 14th Five-Year Plan period. This is the third time that Qingdao has won this honor since 1979 and 1992. In 2023, Qingdao Football has achieved full coverage of football professional clubs at all levels, including Super League, China A, China B, Women A and Five Super League.

The achievement of such excellent results is inseparable from Qingdao’s policy support for football development.

In terms of support for professional sports clubs, Qingdao Sports Bureau issued the Measures for Supporting and Encouraging High-level Professional Sports Clubs in Qingdao according to the spirit of the document "Implementation Opinions on Promoting National Fitness and Sports Consumption to Promote High-quality Development of Sports Industry". The Qingdao Municipal Sports Bureau will set up a sports industry support incentive fund, which will invest 35 million yuan every year to support the high-level professional sports clubs in Qingdao, and reward them according to the results of professional leagues.

In November of the same year, the leading group for the promotion of football reform and development in Qingdao also issued the "Construction Plan of National Key Cities for Football Development in Qingdao during the Tenth Five-Year Plan". The plan clearly sets the goals to be achieved by 2025, focusing on building 1-2 super league teams; Realize the 9-level elite echelon of Super League Club and the 7-level elite echelon of Zhongjia Club; Set up 1-2 professional women’s football clubs … and the goal of focusing on building 1-2 super league teams was first fulfilled this autumn.

Looking at the whole country, there are only a handful of cities that can be called "football cities". Qingdao has enjoyed a good reputation for many years, which is inseparable from its excellent youth training system and good youth football competitions.

For a long time, Qingdao youth football has a profound foundation and outstanding achievements in youth training. The traditional event "Mayor Cup" campus football league has gone through 32 seasons. The league also achieved full coverage from the primary school, junior high school, senior high school and university four-level campus football league system. By the end of 2021, the "Mayor Cup" campus football league had organized 3,694 games, in which 22,553 players from 1,510 teams participated. Qingdao campus football is constantly exploring the deeper field of integration of sports and education. The introduction of a series of security policies and the practice of trying first provide protection for children who like playing football and take care of their studies.

By 2023, 10 Qingdao athletes, including Wang Ziming, Liu Yang, Li Lei, Wei Zhang, Wang Haobin, Li Suda, Liu Chen, Zhang Yiqian, Shuo Yang and Shao Mingzhen, have been selected into national football teams at all levels, and outstanding talents are constantly emerging; Qingdao U9-U14 football team won five championships in six groups in the 2023 Shandong Football Championship, and Qingdao U16 women’s football team became the first team to advance to the top four of the National Student (Youth) Games, with excellent competitive results.

In addition, Dong Lu, a well-known football commentator, also praised Qingdao’s youth training in the recent live broadcast. He said that Qingdao has a large number of football talents and good football development genes. Youth training clubs such as Qingdao West Coast Football Club and Qingdao Zhuifeng Youth Football Club have performed very well on the field, and many high-level athletes and coaches are also impressive.

"Fight, Qingdao team!" It is not only a slogan, but also engraved into the football memory of a generation.

Counting the football history of Qingdao, at the beginning of the China Professional League, Qingdao established its own professional team-Qingdao Manatee. The time can be traced back to December 31st, 1993. Qingdao Manatee Football Club was formally established, and it became one of the founding teams of Chinese Football Association Super League together with Shandong Taishan, Beijing Guoan, Tianjin Jinmenhu and Shenzhen Team.

In 2002, Qingdao Yizhong Manatee hired Li Zhangzhu, a famous Korean coach, as the head coach, and the team won the China Football Association Cup, which was the first national championship in the history of Qingdao professional football. Qingdao Huanghai Qinggang Team won the championship in the 2019 season and successfully overtook it. In the 2020 season, Qingdao Manatee Team and Qingdao West Coast Team also staged the "Qingdao Derby" in the second season. In the 2021 season, the Qingdao Manatee team took the lead in rushing to the A, and the West Coast team subsequently succeeded in rushing to the A in the play-offs of the 2021 season. In the 2022 season, the two teams will continue to stage the "Qingdao Derby" in the Chinese team. Last year, the Manatees took the lead in overtaking, and the West Coast team gained a foothold in the Chinese team. By the 2023 season, the West Coast team was successful, while the Manatee team was successful in relegation in the Super League.

At the recently concluded 2023 China Qingdao Fashion Sports Industry Conference, Liu Jianhong attended as a guest, also talked about Qingdao at the scene, and praised the development of Qingdao football. He said, "In 1996, as a reporter of CCTV’s Football Night, I came to Qingdao to interview League A and B, and witnessed the process of the Manatees returning from League A to League A that year." After leaving CCTV, Liu Jianhong came to Qingdao again in 2021. He presided over the expedition ceremony of Qingdao Manatee. The Manatee was successfully upgraded from B in that year, and it was successful at the end of 2022. Today, the Manatee has become a strong force in the Super League again. As a football city, Qingdao and Liu Jianhong have witnessed the ups and downs of Qingdao football for so many years.

In the long history of football development in China, Qingdao football has experienced ups and downs, but it has never been absent.

Derby is an unavoidable topic in a region where football is booming. Two teams in the same region staged a "peak showdown", accompanied by tens of thousands of fans shouting like a tsunami, the two sides joined hands in the game to contribute to the offensive and defensive war, and the fierce physical confrontation and the collision of beliefs among fans undoubtedly made it the most eye-catching game at present, which also made the football economy "hot"!

Looking around the world, there are the famous Manchester derby and North London derby in the Premier League, the national derby between Real Madrid and Barcelona in La Liga, the "Milan duo" in Serie A, and the most intense national derby between Boca and Riverbed Argentina.

In China, the derby in the same city is also one of the most concerned games. Compared with the "Jinglu War" and "Jingyue War", the once Guangzhou Derby, Wuhan Derby and Tianjin Derby gradually disappeared from public view with the fading of "Jinyuan Football". Now, the joining of Qingdao Derby not only injects fresh blood into the league, but also appears more precious in timing.

Looking forward to the 2024 season, Qingdao will usher in the "city derby" of the Super League for the first time, Qingdao manatee and Qingdao West Coast will usher in "love and kill each other", and the "football economy" will gradually spread from the north shore of Jiaozhou Bay, which was on fire this year, to the west coast of Jiaozhou Bay. At that time, the two teams will also dedicate a wonderful showdown for Qingdao and even the national fans.

One city "double super"! This is an affirmation of the hard work of Qingdao football for many years, and it has injected a "cardiotonic agent" into the development of Qingdao football. Whether manatees avoid relegation, or the West Coast overtake, or the gradual improvement of the youth training system, to a certain extent, it reflects the long-term vision and unremitting pursuit of Qingdao’s football career development.

Dapeng rises with the wind in one day, soaring to Wan Li. In the future, Qingdao Football will take advantage of the east wind of "building a key city for national football development" to vigorously promote the deepening of football reform, do a good job in training and transporting youth football, comprehensively improve the overall development level of football, and make the reputation of "Football City" a "golden signboard" of Qingdao.

　　CCTV News:As the "crown jewel" of modern industry, aero-engine has always been a "heart disease" of China aviation industry. With the establishment of China’s 12th military enterprise in Beijing, Chinese people have high hopes for this aero-engine enterprise, hoping that it can achieve the same achievements as "two bombs and one satellite".

　　Yesterday, the four-day air force aviation opening activity came to an end, and more than 20 military aircraft in the 34-type domestic weapons and equipment attracted national attention.

△ On September 2, 2016, the 2016 Changchun Aviation Open Day was held in the rain, in which a variety of air force active equipment such as H-6K, JL10, JL9 and Air Police 500 were unveiled.

　　At the same time, it also brings people cold thinking: what is the current localization ratio of the big country air force, which has a huge demand for aero-engine industry, and what level has it reached? How far are we from the aero-engine power?

　　Guogui Wu Decryption: Localization has gone through the process of introduction, imitation, improvement and innovation.

　　Guogui Wu, a 57-year-old special pilot of the Air Force, holds the rank of senior colonel. He used to be the captain of the Air Force Bayi Air Show Team and the deputy division commander of an Air Force Aviation Division, with 30 years of flying experience. As an old pilot with actual combat experience, and now a professor in the post-installation teaching and research department of National Defense University, he has unique insights in studying military high-tech, air force weapons and equipment, and equipment safety management.

　　At present, what kind of level is the localization ratio and performance of aero-engines in China? Guogui Wu said in an interview that China has established an independent aero-engine industrial system in the process of industrialization, and the performance of imitation engines reached a very high level in the 1960s and 1970s.Among the main combat aircraft, domestic engines have accounted for about 90%.

　　The so-called localization here refers to the process of introduction, imitation, improvement and innovation.Due to China’s weak industrial base, in order to meet the strong military demand for aero-engines, the Soviet Union’s aid and imported production methods were adopted. On the basis of the introduction and digestion of Soviet engine production technology, the model was improved, and the scale and serialization of domestic production were gradually realized, which basically met the needs of China’s air, land and sea aviation forces.

　　In the 1960s and 1970s, the overall performance of aero-engines produced in China was not much different from the mainstream level in the world at that time. The fundamental difference was that the domestic engines were mainly imitations and modifications, and there was no engine that was completely independently developed and produced.

　　"Not only do we have no independent intellectual property rights, but we also have no core technology." Guogui Wu said, therefore, in the 1980s and 1990s, when the aviation technology of the United States, Europe and Russia developed rapidly, and the third generation fighters were generally equipped with a new generation of turbofan engines, China was still "playing around" in the improvement of turbojet engines, hesitating on the road of introducing imitation and independent innovation, and the gap between China and the world’s advanced level was not large. Not only does the new generation of fighters lack the drive of advanced engines, but the engines in service also have some quality and safety hazards, which are called "heart disease" by Chinese people.

　　Only a few third-generation aircraft of the main fighter are equipped with imported engines.

　　△FWS10 aero-engine is an advanced aero-turbofan engine designed and manufactured by China. It is installed on the domestic J -11 aircraft and can also be installed on the J -10 aircraft after modification. Now it has been mass-produced. It has become an ideal device for the third generation fighter in China.

　　After 60 years of development, China has fighter planes, bombers, attack planes, transport planes and trainers.Systematize the aircraft production capacity of many types of aircraft. In line with this, a relatively complete engine development and production system has been established, which has the series development and production capacity of turboprop, turbojet, turbofan and turboshaft engines. Domestic engines are mainly assembled on fighter planes, fighter planes, bombers, fighter bombers and other main battle planes, and only a few third-generation fighters are equipped with imported engines.

　　For example, domestic fighters such as J -5, J -6, J -7 and J -8 are adapted to corresponding domestic engines such as turbojet -5, turbojet -6 and turbojet -7. With the improvement of stability, safety and reliability of Taihang engine, it has been widely installed on three generations of fighters, such as J -11, J -15 and J -16.

　　In terms of bombers, H -5 and H -6 realized the localization of engines. The turboprop engines used in Yun -7 and Yun -8 transport planes are all made in China.

　　With the maturity of integral technologies such as Zhi -9, Zhi -8 and Zhi -10, the serial development of turboshaft -8, turboshaft -6 and turboshaft -16 engines has been realized on the basis of introduction, which provides a reliable power source for the rapidly expanding domestic helicopter fleet in China.

　　At present, China’s aviation industry is in a stage from big to strong, from following up to catching up to developing on a par or even surpassing corners. Whether it is a new generation of military aircraft such as fighters, bombers, transport planes and drones, or large passenger planes and all kinds of general-purpose aircraft, there is an urgent need for strong and reliable driving of advanced engines. The sound and rapid development of aero-engines has become the proper meaning of the "Chinese Dream".

　　Guogui Wu said frankly that the country has clearly regarded the engine as a major scientific and technological project in the medium and long-term scientific and technological development plan, and has made up its mind to concentrate manpower, material resources and financial resources to independently research and develop a series of new engines. Domestic aero-engines have entered an unprecedented fast lane of development. In this context, the establishment of China Aviation Engine Group can be said to have a long way to go.

　　Development history of aero-engines in China

　　Stage 1: imitation and improvement

　　In 1950s, China aero-engine industry started from scratch and went through a road full of thorns. In 1956, China’s first turbojet -5 engine was successfully copied in Shenyang, and for a long time thereafter, China aero-engines were mainly copied and improved.

　　Even if it is copied, it is not easy. Even if there is no operation manual, it is difficult to disassemble the aero-engine correctly. For example, there are many small holes on the leaves of several square meters and centimeters, and the location of the small holes is very particular, which is determined according to the recorded trend.

　　Until 2002, when the domestic turbojet -14 "Kunlun" engine was finalized, China completed the whole process of self-development for the first time, and became the fifth aero-engine producer after the United States, Russia, Britain and France.

　　Stage 2: successful localization by purchasing patents.

　　The engine used in the flying leopard fighter is made in China and is called "Qinling", which is alsoIt is the first engine product in China that has been patented and successfully localized.

　　From introduction to localization, it has experienced 30 years of industrial upgrading. In 1972, China contacted Britain to discuss the introduction of the civil turbofan engine from rolls royce. In 1974, during the negotiation, to our surprise, China directly obtained the patent of Spey military engine, which was a top product at that time.

　　However, despite the patent, China’s new industrial materials and other technologies were too backward at that time. It was not until 2013 that this road of localization was completed, and it was equipped on the J-H -7 Flying Leopard fighter, and Flying Leopard became the only main fighter in China that completely got rid of its dependence on imported engines.

　　Stage 3: Own independent intellectual property rights.

　　In December 2005, turbofan -10, also known as "Taihang" engine, was successfully developed and became my engine.China’s first high-performance turbofan engine with independent intellectual property rights.

　　The road to research and development of Taihang engine is also quite difficult. During the test flight, more than 200 technical problems and failures occurred successively. After hard work, the "Taihang" engine was finally equipped on the J -15 fighter and successfully made its first flight in 2012. On a group of J -20 equipment exposed at the beginning of this year, some military fans found that a J -20 was also equipped with an improved Taihang engine. Some military experts said that the "Taihang" engine can be directly equipped on the fourth generation fighter, which laid a good foundation for continuing to develop more advanced, mature and reliable engines in the future.

　　Xinhua News Agency, Beijing, December 19th Special feature: Finding the way in the changing situation — — Review of the International Situation in 2019

　　Xinhua News Agency reporter Ban Wei

　　In 2019, the second decade of the 21st century is coming to an end.

　　This year, the world was full of chaos and challenges: the game between big countries intensified, the governance deficit increased, and the world economy continued to slump. The characteristics of the accelerated evolution of the "great change in a hundred years" are more obvious: the dispute between multilateralism and unilateralism is more acute, protectionism and populism are surging against the current, and power politics and bullying are rampant everywhere.

　　This year, globalization and multipolarization are still moving forward with heavy burdens in twists and turns, and a new round of scientific and technological revolution and industrial transformation is emerging. More and more countries are seriously thinking about what choices should be made in the contest between cooperation and confrontation, multilateralism and unilateralism, and openness and closure.

　　The Sound and the Fury

　　The change of the "2019 edition" shows that the game between big countries has obviously warmed up.

　　Near the end of the year, NATO held a "70th birthday party". However, American leaders repeatedly complained that "NATO is out of date", demanded NATO member countries to substantially increase their military spending, and called the EU an "enemy" of trade. France said that NATO experienced "brain death" and so on, which made the party "play inharmony", and the wrestling of all parties increased. NATO tasted the birthday cake with "trust deficit".

　　The German newspaper Le Monde said: "NATO is now threatened from within." Gusev, director of the Russian Institute of Strategic Planning and Forecasting, said: "The complicated relationship between the United States and NATO allies complicates the current international relations."

　　This is the latest epitome of the widening rift in traditional relations in western countries. In one year, the G-7 held a summit, but only issued a "one-page statement" that lacked substance, highlighting internal differences and weak influence. As the world’s largest economy, the United States has repeatedly opened new fronts in the global trade war. After announcing the imposition of tariffs on EU aviation and agricultural goods, it plans to retaliate against French digital tax … …

　　During the past year, Russia hoped that Russia-US relations would return to normal, but frankly this situation has not yet appeared, and relations with the United States are "regressing and getting worse and worse". Although Russia and Europe have released in good faith from time to time, improving relations is facing challenges. Japan’s Diplomatic magazine said that "cold peace" seems to be becoming the new normal of bilateral relations.

　　The change of the "2019 edition" shows that anxiety, tearing and chaos are staged in many parts of the world, and the uncertainty is further increased.

　　Political struggles in Latin American countries have intensified, and governance problems have become prominent; The confrontation between Iran and the West and the Syrian conflict are intertwined, which intensifies the turmoil in the Middle East and presents a peace deficit. Britain’s "Brexit" has been delayed for a long time, revealing social tears and institutional difficulties; The United States continues to "retreat from the group" and tries to make the United States "great again" through unilateralism and protectionism, which has impacted the international order.

　　The change of the "2019 edition" is also manifested in the continued downturn of the world economy. Georgieva, the new managing director of the International Monetary Fund, said that trade disputes, Britain’s "Brexit" and the uncertainties brought about by geopolitical tensions are inhibiting the global economic growth potential. IMF predicts that the global economic growth this year will be the lowest since the international financial crisis in 2008.

　　The sunshine behind the dark clouds

　　In the changing world, people can still touch the development force in the deep dive. The light coming out of the clouds still indicates the general trend of global development.

　　In the face of changes, "everyone is also looking for new alternatives and ways out." Zheng Yongnian, a professor at the Institute of East Asian Studies at the National University of Singapore, pointed out that it is a general trend for more countries to jointly promote multilateralism while some western powers are pursuing economic nationalism and unilateralism.

　　This year, in the face of counter-current, globalization is making efforts to take new steps. On November 4th, the Third Regional Comprehensive Economic Partnership Agreement (RCEP) leaders’ meeting issued a joint statement, announcing that the 15 member countries had concluded all text negotiations and virtually all market access negotiations. The publication of the joint statement marks a major breakthrough in the construction of the East Asia Free Trade Area with the largest population, the largest membership structure and the greatest development potential in the world, highlighting that multilateralism and free trade are still the mainstream in the world.

　　Yu Jie, a senior researcher at the Royal Institute of International Affairs, believes that the breakthrough in RCEP negotiations plays an exemplary role in solving the development problem of economic globalization and sets an example for developing countries to seek the right to speak in global governance.

　　Earlier, the construction of a free trade area on the African continent was officially launched, and the "marathon" negotiations between MERCOSUR and the EU Free Trade Agreement finally came to fruition. Today, with the increasing downside risks of the world economy, more and more countries realize the importance of maintaining free trade and a rules-based multilateral trading system for hedging risks and seeking growth.

　　This year, the world saw the trend of the continuous development of multipolarization. In the great changes, emerging markets and developing countries, represented by BRICS countries, are constantly rising, which has injected strong impetus into the reform of the global economic governance system and effectively promoted the process of world multipolarization.

　　This year, the world saw that a new round of scientific and technological revolution and industrial transformation was emerging. The limit of growth has always been a haze lingering over the development of human society. Nowadays, people are increasingly seeing the bright future of innovation-driven solution to the development difficulties.

　　In the past year, the world began to enter the stage of 5G commercial deployment, and the transformation of old and new kinetic energy accelerated; AI intelligence in all fields has provided a broad blue ocean for economic development; New breakthroughs have been made in quantum computing, and its prospects are limitless. The new scientific and technological revolution and industrial transformation have provided more opportunities for countries to achieve leap-forward development, and also made it an inevitable logic for countries to increasingly blend interests, share common destiny and win-win cooperation.

　　人类群星闪耀时

　　回望2019年的国际风云，中国理念、中国方案、中国贡献，作为顺应和推动全球发展大势的重要力量，在乱局中引领方向。

　　中国主张和担当为多边主义、多极化和完善全球治理注入强大正能量，推动构建新型国际关系。

　　一年间，国家主席习近平7次出访，主持4次主场外交。元首外交维护世界和平，促进共同发展，捍卫多边主义。从二十国集团领导人峰会到中法全球治理论坛，从“一带一路”国际合作高峰论坛到金砖峰会，中国维护多边主义、加强全球治理、推动世界多极化主张引发广泛共鸣。国际上的事应该由大家商量着办，不能由一国或者少数几个国家说了算，成为越来越多国家的共识和心声。

　　谈及中国在当今世界格局中的作用和地位，法国前总理拉法兰说，中国扮演着非常重要的角色，是世界经济增长的引擎。中国参与构建新型多边主义，助推亚洲以及非洲在国际体系中的地位提升。

　　中国以实际行动，为建设开放型世界经济作出表率。

　　第二届中国国际进口博览会在6天里，累计意向成交711.3亿美元。“越办越好”的进博会，交易的是商品和服务，交流的是文化和理念，种下的是开放、合作、共赢的种子。

　　布鲁金斯学会约翰·桑顿中国中心主任李成认为，不论是“一带一路”建设，还是第二届中国国际进口博览会，中国都更多体现出包容性增长理念，强调共同发展、共享经济，这表明中国并不是一花独放，而是愿与世界共同发展。

　　中国倡导的构建人类命运共同体理念，为追寻人类文明的群星闪耀指明方向。

　　“这是最好的时代，这是最坏的时代。”在一首今年风靡网上的歌曲中，一名中国草根歌手借用英国作家狄更斯的名句，唱出人们对当今矛盾世界的感悟。

　　就世界如何应对风险与挑战、寻求平等与共赢、消除傲慢与偏见，中国给出答案：既需要经济科技力量，也需要文化文明力量。在构建人类命运共同体的目标引领下，倡导多元文明共生并进，用文明对话促进沟通与理解，将让人类前进的道路越走越宽广。

　　“当前，世界多极化、经济全球化、文化多样化、社会信息化深入发展，人类社会充满希望。”习近平主席今年5月在亚洲文明对话大会开幕式上的这番话，针对充满不确定性的当今世界，发出提振信心的强音。（参与记者：栾海、张骁、王丽丽、桂涛、徐永春、韩茜、刘品然）
