Will table tennis bouncing on the blue table, football rolling on the pitch and badminton flying one day become "close partners" with artificial intelligence?

At the recently concluded Tokyo Olympic Games, the China table tennis team scored four gold medals and three silver medals, which also made a scientific research team behind it, the Zhejiang University Sports Big Data Innovation Team, appear.

What different landscapes have this innovative team brought to competitive sports by using artificial intelligence? Recently, the reporter went to the State Key Laboratory of CAD&CG of Zhejiang University to find out.

Unexpected intelligent ping-pong

On July 29th, in Tokyo Gymnasium, the semi-final of women’s singles table tennis was in full swing. You wouldn’t expect that besides the athletes, referees and few spectators in the stands, there is also a powerful artificial intelligence platform monitoring the game.

Every serve, swing, move, etc. on the field is recorded by this AI cloud platform deployed in Tokyo. These data are transmitted to the technical team of "table tennis intelligent big data analysis platform" 2442 kilometers away from the gymnasium at an average speed of 100 megabytes per second.

Almost at the end of the game, a technical and tactical analysis report about the game was immediately pushed to the tablet computers of the coaches and athletes of China table tennis women’s team by the AI cloud platform. These latest game videos and technical and tactical data analysis reports are directly used for the follow-up preparations of China table tennis women’s team.

The reporter learned that technical and tactical data used to be collected by watching videos after the game. However, because the speed of table tennis is too fast, researchers often can’t quickly, accurately and comprehensively mark all the athletes’ game behaviors, such as players’ hitting skills, landing points, positions, racket sequences and other information. It sometimes takes about 5 hours to collect detailed data of a game and make in-depth and detailed analysis.

This work is not only time-consuming and laborious, but also very challenging.

How to delete redundant relay shots, accurately identify the score changes of each round, detect and locate each beat, and efficiently label the data automatically or semi-automatically, has become a scientific research difficulty.

Deng Dazhen is a fourth-year doctoral student in the State Key Laboratory of CAD&CG, School of Computer Science, Zhejiang University, and a member of the sports big data innovation team of Zhejiang University. Deng Dazhao told reporters that in order to solve this problem, he and two classmates spent three months building a special model and realizing round segmentation, and developed an interactive data labeling method in the following year, successfully achieving high-quality data collection.

Professor Wu Yingcai, the doctoral supervisor of Deng Dazhao and vice president of the School of Computer Science and Technology of Zhejiang University, is the main developer of this intelligent big data analysis platform for table tennis that can "update combat effectiveness in real time". On the front line of AI cloud platform, it is Professor Zhang Hui, director of the Department of Physical Education, School of Education, Zhejiang University, who makes further analysis and feeds back key information to coaches and athletes in time. The two of them are also key figures in the sports big data innovation team of Zhejiang University. With the support of the State Sports General Administration and the Chinese Table Tennis Association, this team has been providing services for the national table tennis team in terms of game data analysis and technical and tactical research.

Since 2018, Wu Yingcai led the team to start the annotation analysis and platform construction of table tennis big data. Now, the sports big data innovation team has developed an intelligent big data analysis platform for table tennis based on interactive visual human-computer interface, combined with artificial intelligence algorithm and human experience wisdom, and realized semi-automatic data annotation, analysis and presentation.

This platform continues to make technological breakthroughs, which will shorten the labeling time. 2 hours, 1 hour … Now, the data can be collected as soon as the game is over.

Dr. Zhou Zheng from the Department of Physical Education, College of Education, Zhejiang University, and graduate students and undergraduates majoring in table tennis are responsible for the collection and analysis of competition data. Zhou Zheng and his mentor Zhang Hui have been deeply involved in the training and competition of the national table tennis women’s team for a long time. In addition to the Tokyo Olympic Games, they also participated in the series of competitions of the national table tennis team in preparation for the 2019 World Championship and World Cup, and produced a large number of targeted technical and tactical analysis cases and statistical reports, which contributed to the excellent achievements of the China table tennis team.

Now, the Tokyo Olympic Games has ended, and the China table tennis team has once again proved its strength, which also makes the scientific and technological forces behind it shine brilliantly on the world stage.

From evaluating technology to formulating tactics

Surprisingly, the table tennis intelligent big data analysis platform can not only evaluate technology, but also formulate tactics. This opens up a new direction for human-computer interaction.

The reporter noted that the application of artificial intelligence to the field of table tennis is nothing new. In 2011, two humanoid robots "Wu" and "Kong" developed by the Robotics Laboratory of the Institute of Intelligent Systems and Control of Zhejiang University were officially unveiled. These two robots that can play table tennis can capture the movement track of table tennis in the air through the camera mounted on their heads, predict the impact point of the ball, and then make corresponding response actions, and even achieve a fight with people. The table tennis intelligent big data analysis platform developed now is mainly aimed at the training and competition of excellent athletes, helping coaches and athletes to better observe, understand and analyze the technical and tactical advantages and disadvantages of their opponents and themselves, so as to know ourselves and ourselves.

It turns out that an important aspect of table tennis technical and tactical analysis is to judge the quality of players’ hitting. This requires coaches and researchers to manually evaluate the quality of athletes’ shots on the spot or when watching the game video. Another question arises from this: what to do when the number of competitions is very large; If there are 100 or even 1000 videos, can such a task be completed?

Therefore, evaluating the quality of swing has also become a goal that sports big data innovation teams need to achieve.

The first thing they need to solve is how to let the computer learn the knowledge of professional table tennis players, and combine a series of attributes such as the technology used in each beat, the hitting position and the landing point to objectively and accurately evaluate the player’s hitting process. In order to solve this technical problem, from last year, Wu Yingcai began to tackle key problems through team cooperation with Professor Zhou Zhihua of Nanjing University. This year, they finally made important progress and original achievements.

"We use the theoretical framework of deductive learning to integrate more than 30 table tennis technical and tactical rules into data-driven machine learning, and develop a framework that can automatically evaluate the quality of swing." Wu Yingcai said that deductive learning can perfectly integrate data-driven machine learning technology and rule-driven artificial intelligence technology. Now, as long as the game video is input on the analysis platform, the hitting quality of each shot of the athletes in the video can be automatically obtained.

By overcoming the difficulties step by step, there are more than 8,000 high-precision competition data of international competitions on the table tennis intelligent big data analysis platform. Since 2018, the research team has started the simulation prediction of the game based on these data, and truly upgraded from technology to tactics. "With big data and artificial intelligence, we can simulate and deduce to predict how the winning percentage will change when our players change a certain skill and tactics." Wu Yingcai said.

This idea has also been applied to badminton. Xie Xiao, a special researcher in the Department of Physical Education, Zhejiang University, demonstrated a new system being developed by the team.

As long as you wear a VR helmet, you can see the tracks left by athletes waving badminton rackets on the court. At the end of a game, all the action tracks are presented on the computer screen, as if countless "ribbons" were thrown in the air. These "ribbons" are grouped and classified and distinguished by color.

This is Shuttlespace, an immersive analysis system that can help experts analyze badminton data. Xie Xiao said that in the traditional analysis, the video of badminton match is separated from the analysis chart, which makes people unable to intuitively perceive the real situation on the court. Shuttle Space uses virtual reality technology to simulate the three-dimensional trajectory of man and ball in the most realistic form, which is enough for experts to perceive and analyze the data from the player’s subjective perspective and better formulate tactics.

Cute and curious,

Animals that have always been known as "stupid"

Do you know who it is?

Yes, it is the northeast god beast-roe deer!

It is a national second-class protected wild animal.

Do you think it is?

Actually, it looks like this …

At 22 o’clock on the evening of August 28, the patrolling police of Xinying Police Station received a call for help from Ding Mou, a resident of the jurisdiction, saying that he had picked up an injured animal suspected of being a "goat" in the Shuiquan section of the county. After receiving the police, the police immediately rushed to Ding’s home. After careful inspection, this "goat" had a collision wound on one hind leg, but it did not hurt the bone and was able to stand.

The patrol police first fostered him in the sheepfold of Wang Moumou, a villager in the jurisdiction, and immediately contacted the forest police station of Xiji County Public Security Bureau to identify the animal. It turned out that the scientific name of this "goat" was roe deer, also known as dwarf deer, a herbivore of Artiodactyla and a national second-class protected animal. Afterwards, the police of the forest police station disinfected and bandaged the wound of the robe.

On the morning of August 29, after a night’s rest, this roe deer looked agile and in good mental state. Everyone called it a cute treasure. After confirming that it had the ability to survive in the wild, it was taken to the mountains and forests and released to nature.

In recent years, with the gradual improvement of the ecological environment in our county

More and more wild animals are trespassing into the living area by mistake.

The awareness of the broad masses to protect wild animals

It is also growing.

Let’s join hands.

Protect green mountains and green waters together

Build the beautiful scenery of harmonious symbiosis and coexistence between man and nature.

Xiji Public Security reminds me here.

When discovering wild animals, you must not rescue them privately or release them blindly. You should call the police or get in touch with the wildlife protection department in time so that the animals can be released scientifically after being rescued in time.

Legal link:

According to Article 341 of the Criminal Law of People’s Republic of China (PRC): "Whoever illegally hunts and kills rare and endangered wild animals under special state protection shall be sentenced to fixed-term imprisonment of not more than five years or criminal detention and fined; If the circumstances are serious, he shall be sentenced to fixed-term imprisonment of not less than 5 years but not more than 10 years and fined; If the circumstances are particularly serious, he shall be sentenced to fixed-term imprisonment of more than 10 years and fined or confiscated.

　　Core reading

　　As of this year, the Ministry of Ecology and Environment has carried out air pollution supervision and assistance in autumn and winter for five consecutive years. In the past five years, it has helped local governments find 284,000 problems, comprehensively found out the environmental problems of air pollution in key areas, and fully guaranteed the successful completion of the "Thirteenth Five-Year Plan" pollution prevention and control target.

　　□ Our reporter Qi Jianrong

　　With the recent issuance and implementation of the Plan for Comprehensive Control of Air Pollution in Autumn and Winter in 2021-2022 (hereinafter referred to as the Action Plan), the action to combat air pollution in autumn and winter in key areas in 2021-2022 has been fully launched. According to the requirements of the Action Plan, the Ministry of Ecology and Environment will continue to carry out atmospheric supervision and assistance in key areas such as Beijing-Tianjin-Hebei and surrounding areas to ensure the double reduction of heavily polluted weather and PM2.5 concentration.

　　According to Li Tianwei, inspector of the Law Enforcement Bureau of the Ministry of Ecology and Environment, as of this year, the Ministry of Ecology and Environment has carried out air pollution supervision and assistance in autumn and winter for five consecutive years. In the past five years, it has helped local governments find 284,000 problems, comprehensively found out the environmental problems of air pollution in key areas, and fully guaranteed the successful completion of the "Thirteenth Five-Year Plan" pollution prevention and control target.

　　Li Tianwei pointed out that this autumn and winter, the Ministry of Ecology and Environment will send a professional supervision and assistance team to strengthen supervision and law enforcement around key areas such as automatic monitoring and pollutant discharge permit, so as to do nothing to disturb law-abiding people and carry out precise strikes against offenders.

　　Found 284,000 problems in 5 years.

　　Suzhou Wanshen Flour Products Co., Ltd. (hereinafter referred to as Wanshen Company), located in Dongshili Circular Economy Park, Yongqiao District, Suzhou City, Anhui Province, mainly produces starch and has a 60t/h coal-fired boiler. According to the requirements of EIA approval, the boiler exhaust gas of Wanshen Company needs to be treated by SNCR denitration, bag dust removal and desulfurization wet electric dust removal integrated device, and then discharged through a new chimney equipped with automatic monitoring equipment.

　　However, in September this year, the law enforcement officers of the air quality improvement supervision and assistance working group in key areas sent by the Ministry of Ecology and Environment found during on-site inspection that part of the exhaust gas of Wanshen Company was not treated by the integrated desulfurization, wet electrostatic precipitation device, but was directly discharged through the abandoned old chimney without automatic monitoring equipment. This kind of behavior of Wanshen Company is a typical way to evade supervision and discharge air pollutants to pollute the environment.

　　Coincidentally. At the same time, Fuxin Liaoning Zhonghui Biotechnology Co., Ltd. stole air pollutants through emergency pipelines, Jinzhong Shanxi De Sheng Da Chemical Co., Ltd. stopped pollution control facilities without authorization, and air pollutants were discharged directly. A number of problems such as air pollutants discharged by Tangshan Rongyi Coking and Gas Making Co., Ltd. were verified.

　　In order to promote the continuous improvement of air quality in key areas, in early September, the Ministry of Ecology and Environment sent 16 professional groups and 46 regular groups to go deep into key areas to carry out air quality improvement supervision and assistance. Including Wanshen Company, Fuxin Zhonghui Biological, Jinzhong De Sheng Da, Tangshan Rongyi and other enterprises, were all found on the spot during this supervision and assistance.

　　According to Li Tianwei, the atmospheric supervision and assistance organized by the Ministry of Ecology and Environment began as early as 2017 and has lasted for five years this year.

　　"Since 2017, the Ministry of Ecology and Environment has coordinated the system-wide eco-environmental law enforcement team and backbone forces, and creatively organized and implemented atmospheric supervision and assistance in key areas." Li Tianwei said that through the investigation of more than 40 key special tasks, a total of 284,000 problems have been found in local areas, the environmental problems of air pollution in key areas have been comprehensively clarified, and the gap and crux of the formulation of policies, regulations and standards and the landing of tasks and measures have been identified, which has promoted the resolution of a large number of gas-related environmental problems.

　　According to Li Tianwei, since the 14th Five-Year Plan, the Ministry of Ecology and Environment has optimized and adjusted the supervision and assistance mechanism. This summer, this new mechanism was applied to the supervision and assistance of ozone pollution prevention and control in summer, focusing on key regional cities such as Beijing-Tianjin-Hebei and its surrounding areas, Fenwei Plain, and digging into key industries such as steel, coking, petrochemical, chemical and building materials, and found a large number of outstanding problems such as by-pass emissions, non-installation or abnormal operation of pollution control facilities, abnormal operation of automatic monitoring or fraud, and assigned more than 10,000 local gas-related environmental problems, thus realizing the new mechanism.

　　According to Wu Xianfeng, deputy director of the Atmospheric Environment Department of the Ministry of Ecology and Environment, since 2017, the air quality in key areas has been continuously improved through the implementation of the autumn and winter atmospheric attack. Among them. In autumn and winter of 2020, the concentration of PM2.5 in Beijing-Tianjin-Hebei and its surrounding areas and Fenwei Plain decreased by 37.5% and 35.1% respectively compared with the same period of 2016, and the days of heavy pollution decreased by 70% and 65% respectively. The Yangtze River Delta has basically eliminated the heavy pollution weather.

　　Heavy polluted weather still happens from time to time.

　　The Action Plan jointly issued by 10 ministries and commissions including the Ministry of Ecology and Environment, the National Development and Reform Commission and the Ministry of Industry and Information Technology, and the governments of seven provinces (cities) including Beijing, Tianjin and Hebei shows that in autumn and winter of 2020, the concentration of fine particulate matter (PM2.5) in Beijing-Tianjin-Hebei and its surrounding areas and Fenwei Plain showed a downward trend compared with the same period in 2016, and the people’s sense of blue sky acquisition and happiness were significantly improved.

　　At the same time, the Action Plan also pointed out that although positive results have been achieved in autumn and winter, the results of air quality improvement are still not stable. Heavy polluted weather in autumn and winter in Beijing, Tianjin and Hebei and surrounding areas, Fenwei Plain and other areas is still high and frequent, which not only affects the people’s health, but also directly affects the completion of the air quality improvement objectives and tasks in the 14 th Five-Year Plan.

　　Liu Bingjiang, director of the Department of Atmospheric Environment of the Ministry of Ecology and Environment, said that although China’s atmospheric environment has been improving continuously and rapidly, there is still a certain gap between the people’s expectations for blue sky, white clouds and twinkling stars and the goal of building a beautiful China. At present, PM2.5 pollution has not been fundamentally controlled; Ozone concentration is slowly increasing, which has become an important factor affecting air quality after PM2.5. Under unfavorable meteorological conditions, the process of heavily polluted weather still occurs from time to time. In addition, although the structural adjustment has made positive progress, the industrial structure dominated by heavy chemicals, the energy structure dominated by coal and the transportation structure dominated by highways have not been fundamentally changed, and the long-term, complex and arduous atmospheric environmental problems still exist.

　　This year is the first year of the 14th Five-Year Plan. The "Action Plan" pointed out that in the first half of this year, the product output and coal consumption of the "two high" industries rebounded significantly, and the pressure for continuous improvement of atmospheric environmental quality increased. According to Wu Xianfeng, this year’s tough action is mainly aimed at reducing heavy polluted weather and reducing PM2.5 concentration. On the basis of inheriting the effective work in the past, we will stick to the same direction and continue our efforts; Adhere to precise pollution control, scientific pollution control, and pollution control according to law, and further optimize and adjust the scope and measures of tackling key problems; Insist on treating both the symptoms and root causes, promote the adjustment of industry, energy and transportation structure, strengthen regional joint prevention and control, and actively respond to heavily polluted weather; At the same time, scientifically and reasonably set the average concentration of PM2.5 and the target of heavy pollution days in autumn and winter in relevant cities; While tackling the problem of atmospheric control, we will coordinate the stable operation of social economy and the protection of people’s livelihood, and focus on ensuring the supply of energy such as coal and electricity and ensuring warm winter.

　　Wu Xianfeng said that in 2021, the central air pollution prevention and control fund specially arranged subsidies for clean heating operation, and all of them have been distributed to local governments to ensure people’s warmth for the winter.

　　Investigating and handling nearly 200,000 illegal cases.

　　According to Li Tianwei, from 2016 to 2020, a total of 193,300 illegal cases involving gas environment were investigated and dealt with nationwide, with a total fine of 14.051 billion yuan. In the past five years, the proportion of gas-related administrative punishment cases and fines to all administrative punishment cases and fines has increased year by year. Among them, the proportion of gas-related administrative punishment cases to all administrative punishment cases has increased from 11.7% in 2016 to 36.5% in 2020, and the amount of fines has increased from 22.9% to 30.0%, especially the number of outstanding cases such as seizure, production restriction, administrative detention and suspected crime has increased significantly.

　　"Today’s autumn and winter atmospheric supervision and assistance will coordinate the two tasks." Li Tianwei said that one is to promote the task of tackling air pollution control in autumn and winter; The other is to timely investigate the implementation of emergency emission reduction measures according to the forecast and early warning of heavy pollution weather, and promote the "peak cutting and frequency reduction" of heavy pollution weather in autumn and winter.

　　Li Tianwei also revealed that the Ministry of Ecology and Environment is also deepening the application of "Clairvoyance" atmospheric environment remote supervision while organizing the national ecological environment law enforcement team to conduct on-site investigation directly at the ministerial level. "Analyze the high-value areas of fine particles and ozone concentration, identify the fire points and dust sources of straw burning, and push these alarm information to the local authorities. The local ecological and environmental departments will organize verification, give full play to local enthusiasm, and implement territorial supervision responsibilities." Li Tianwei said that "Clairvoyance" divided 428,000 square kilometers of 39 cities in key areas into 60,000 3km×3km grids by using satellite remote sensing, ground micro-stations and big data, and screened 5,000 hot-spot grids with high PM2.5 concentration for "kilometer-level" monitoring, and further accurately identified 1,000 500m×500m small grids for "100 m-level" monitoring.

　　According to Li Tianwei, since 2018, the Ministry of Ecology and Environment has pushed 65,000 pieces of abnormal environmental information to the ecological and environmental departments of 39 cities in Beijing, Tianjin and Hebei and its surrounding areas, and instructed local ecological and environmental departments to investigate 75,000 enterprises and found 51,000 gas-related environmental problems.

　　Li Tianwei pointed out that in autumn and winter this year, the Ministry of Ecology and Environment will continue to stick to the same direction and make unremitting efforts, anchor the goal of improving air quality, especially the goal of basically eliminating heavily polluted weather, continue to organize supervision and assistance work in key areas, and promote the prevention and control of air pollution in key areas during the 14 th Five-Year Plan period.

　　CCTV News:On 23rd, the world’s first floating nuclear power plant built by Russia — — Academician lomonosov set sail for the Arctic Circle.

　　Russian media reported that the only floating nuclear power plant in the world has set out. In the next three weeks, Academician lomonosov will sail nearly 5,000 kilometers along the northern sea route, and its destination is Pevek in Chukchi Autonomous Region. The floating nuclear power plant will be parked there, and its power is enough to supply energy for the whole region. Two reactors can generate up to 70 MW of electricity. By the way, Academician lomonosov will become the northernmost nuclear power plant in the world.

　　On this way, the floating nuclear power plant "Academician lomonosov" will be towed by two tugboats. One tugboat will provide forward power, the other tugboat will be responsible for braking, and a third standby tugboat will accompany it.

　　"Academician lomonosov" mainly provides power for factories, cities and offshore natural gas and oil drilling platforms in extremely remote areas of Russia, with a service life of about 40 years.

　　Its hull is divided into 10 compartments, and even if two compartments are flooded, the hull will remain floating. There are two reactors on board, which can operate even when the inclination angle is nearly 30 degrees. In case of accident, the nuclear power plant can be shut down even if the crew is absent or the power supply is interrupted.

　　The interior of the whole ship is more like a community, and the staff lounge is similar to the hotel room, equipped with TV and Internet.

　　Russian media pointed out that large-scale construction of fixed nuclear power plants will burden the fragile ecosystem in the Arctic, while floating nuclear power plants are more environmentally friendly and economical. Floating nuclear power plants are located at sea far away from land and are not easily affected by earthquakes and tsunamis. Even if there is an earthquake, the seismic wave of the source will not be transmitted by seawater. The ocean itself can also be used as an emergency radiator. In extreme accidents, the floating reactor can introduce seawater into the hull to prevent the core melting process and ensure the safety of the reactor.

　　Xinhua News Agency, Tianjin, October 20 (Reporter Zhou Runjian) The Orion meteor shower, which is most worthy of observation every October, will visit the earth again. Astronomical forecast shows that the meteor shower will reach its peak at 7: 30 Beijing time on the 22nd. Astronomical experts warned that the radiation point of the meteor shower will not rise to a certain height until after 22: 00, so for the Chinese public, the period from the early morning of the 22nd to the dawn is the best observation period.

　　As one of the seven major meteor showers in the world, the mother comet of Orion meteor shower is the famous Halley’s comet, which is the first periodic comet confirmed by human beings, "gestating" the Aquarius Erta meteor shower in the first half of the year and the Orion meteor shower in the second half of the year.

　　Shi Zhicheng, a member of Chinese Astronomical Society and director of Tianjin Astronomical Society, said that the annual active period of Orion meteor shower covers almost the whole October, and its characteristics are very obvious, such as fast meteor speed, many bright meteors, white color and long peak flow duration, which make it more suitable for public observation. Although the meteor shower rarely occurs on a large scale, it is better than the steady flow and never disappoints, so it is still very worthy of attention.

　　"When the Orion meteor shower is at its peak this year, the number of meteors per hour can reach up to 23. For Chinese observers, the ideal observation time is from the early morning of 22nd to before dawn. However, it is a pity that during the peak period, it coincides with the second quarter moon, and moonlight will have a certain impact on observation. " Shi Zhicheng said.

　　Twelve years later, Wang Hongcai knew that there was another "self" in this world.

　　In the past 12 years, she has worked in many places, and another "self" has successfully obtained a college diploma, obtained a nurse qualification certificate and successfully entered the hospital.

　　Obviously, she dropped out of the nursing department of Heze Medical College (hereinafter referred to as "Heze Medical College") for some reason after three days of registration. Twelve years later, Wang Hong unexpectedly saw her college diploma. What made her unacceptable was that the graduation information consistent with her identity information was not her own.

　　Suspected that someone was impersonating herself to go to college, wang hong reported the situation to the school, and a week later, her education was cancelled. She couldn’t figure out why the faulty diploma was cancelled before the impostor was dealt with.

　　What makes her even more anxious is that she doesn’t know, apart from the diploma, did the impostor use his identity information to leave a loan or even a criminal record?

　　have a nightmare

　　For more than 10 years, wang hong has never forgotten the 2005 college entrance examination.

　　That year, wang hong had a stomachache in the examination room, and her performance was abnormal. She had hoped to be admitted to the undergraduate course and was admitted to the nursing department of Heze Medical College.

　　Wang hong is a native of Linyi, Shandong Province, with poor family conditions. In order to go to school, wang hong committed suicide by taking sleeping pills, and the family only collected some tuition fees.

　　Wang hong recalled that she volunteered to make up the newspaper, and when she reported to school, her classmates’ military training was over. "Sign up, pay the money, and then get the daily necessities and books, and the proof of household registration is also given to the school."

　　"A total of 6,900 yuan of tuition fees, the family sold 10 acres of land and made up 4,000 yuan first, and there is no living expenses." Recalling the scene at that time, wang hong felt very bitter. "My dad sent me to school, bought the ticket to go home, walked more than ten miles to school, and gave me the remaining dozens of dollars."

　　However, the rest of the tuition fees can never be collected at home. At that time, each class had two places for national student loans. wang hong said that her parents were both healthy, and there were several students whose family conditions were worse than hers.

　　"There are many classes in the school, and there is no way to work and study. I can’t bear to force my dad to collect money." Three days after reporting for duty, wang hong reluctantly chose to drop out of school and returned the books to the counselor. "At that time, there were two girls who were still reluctant to give up, and I felt it was a pity because my entrance examination results were quite good."

　　"The teacher said that you should retire, but the admission notice is to be recovered, and the tuition fee will be refunded to you." Wang hong recalled, "He also said that your family is so difficult, and the school is very sympathetic. I will give you 1,500 yuan to subsidize your family. I am quite surprised, thinking that the school is so good. "

　　Wang hong returned the books to the teacher and worked to subsidize the family. Wang hong recalled that later, the village committee issued a certificate, and he moved back the registered permanent residence that he had moved out when he entered school, and the registered permanent residence was stamped with "Return due to dropping out of school".

　　"It is certain to look down on you. Everyone else is a college student, and no one cares about me." After dropping out of school, wang hong struggled to find his first job. Since then, she has worked in many places and worked as a substitute teacher, clerk, warehouse manager and salesman. In the past 10 years, she often dreamed that she was at school and always wanted to get a degree.

　　In October 2017, wang hong, who had worked in Jiangsu, consulted about registering for the adult college entrance examination, and entered his ID number on the China Higher Education Student Information Network (hereinafter referred to as "Xuexin.com"), which unexpectedly appeared.

　　According to the Electronic Registration and Filing Form of Education Certificate of the Ministry of Education generated by Xuexin. com, wang hong’s identity information corresponds to a graduation certificate with the number of 104441200806002085. The graduation institution and major are the nursing department of Heze Medical College, which admitted her that year. But the system shows that she graduated normally on July 1, 2008. What makes wang hong even more unacceptable is that the photo in this file is not herself.

　　Wang hong suspected that someone had gone to college under an assumed name.

　　"You have no problem with this (education), and it is normal to learn online." On October 23rd, wang hong called the Academic Affairs Office of Heze Medical College, and the other party gave the same answer after inquiring about her identity information.

　　"But the photo above is not mine." Wang hong told each other that she hoped the school could give an explanation.

　　On October 31st, the Academic Affairs Office of Heze Medical College issued a notice in official website, saying: "wang hong, a graduate of our school in 2008, has a diploma number of 104441200806002085, and his education has been cancelled."

　　For wang hong, the cancellation of the problematic diploma is far from enough. What she is more worried about is whether the impostor has used his ID number to leave a loan or even a criminal record.

　　"I live in great panic every day." Wang hong described the feeling after the incident.

　　Who is the impostor in the photo? How did she get wang hong’s identity information and hide it for 12 years?

　　Wang hong is determined to ask.

　　deadlock

　　"There has never been a similar incident in our school before." On November 27th, when interviewed by China Youth Daily and Zhongqing Online reporter, Wu Xiaolu, secretary of the Disciplinary Committee of Heze Medical College, described the impact of this incident on the school as "no small matter".

　　Wu Xiaolu introduced that the school party Committee attached great importance to it and launched two stages of investigation. The first stage is an initial investigation team led by the Academic Affairs Office, including the relevant personnel of the Academic Affairs Office, the Student Affairs Office and the Supervision Office.

　　With the initial investigation, the information of the impostor Xin Wang gradually surfaced.

　　"What we can confirm now is that after wang hong dropped out of school, Xin Wang bought wang hong’s admission notice through an insider, and then replaced wang hong to go to school until graduation." Jiang Jiguo, director of the Academic Affairs Office, told reporters that according to the investigation, after graduating in 2008, Fake wang hong obtained a nurse qualification certificate and worked in several hospitals.

　　Jiang Jiguo said that the investigation team immediately contacted Xin Wang himself, and Xin Wang said that from the first day of school until graduation, he didn’t know wang hong’s ID number from beginning to end, so there was no way to steal ID information.

　　Jiang Jiguo introduced that in order to be cautious, the investigation team of the school rushed to Heze City Health Planning Commission for further verification, and no nurse qualification certificate was found with wang hong’s own ID number. "The existence of a nurse qualification certificate with Xin Wang’s own ID number needs further verification."

　　Jiang Jiguo said that after the initial confirmation that the impostor was true, the school cancelled the fake wang hong’s diploma at the first time and made further investigation.

　　In Wu Xiaolu’s view, the initial investigation of this matter "has reached a deadlock".

　　At the same time, the slow progress made Wang Hongxin anxious. It’s been one month since I called the academic affairs office of the school for the first time. During this time, the relevant teachers of the academic affairs office and archives management office of the school had five or six telephone calls and QQ communication with wang hong. However, the results of the school’s investigation have been delayed, which makes wang hong feel that "the school seems to have the intention of shielding and shirking".

　　"One is that the time is long, and the other is that the two parties, wang hong and Wang Xin, are not in the local area. It is difficult to investigate and collect evidence. The testimony of the two people on the same thing is quite different and repeated." Wu Xiaolu said.

　　Wu Xiaolu said that wang hong remembered that his nursing professional counselor was surnamed Zhao at that time. After verification by the school, the class counselor at that time was not surnamed Zhao; Wang hong remembers that when the teacher refunded the tuition fee and gave 1500 yuan, there was a Communist Youth League Secretary and two classmates present. The school called the Communist Youth League Secretary of this class who is now far away in the northeast. The other party remembered wang hong, but he had no impression of the scene of tuition refund.

　　Jiang Jiguo also cited Wang Xin as an example. He once admitted that wang hong knew the purchase notice at that time, but wang hong firmly denied it, saying that he had never seen Xin Wang.

　　"How can I sell the admission notice to a stranger casually?" In a telephone interview with a reporter from China Youth Daily and Zhongqing Online, wang hong asked angrily.

　　As for the surname of the counselor teacher, wang hong emphasized that when he had only been in school for three days, all the students around him called the teacher Miss Zhao, and he followed suit, which did not rule out that everyone had identified it incorrectly at that time.

　　"At first she (Xin Wang) lied that her father gave you money. Now we are investigating, and she says that it was not given by her father, but by the teacher. Which teacher is specific, she does not say. " On November 25th, Jiang Jiguo told wang hong on the phone.

　　"This is definitely not a teacher’s problem. It involves several teachers. We must find out what role several teachers participate in and play." He also said.

　　From November 24th, Heze Medical College started the second phase of investigation, with the Commission for Discipline Inspection as the main body. In Wu Xiaolu’s view, "the formal involvement of the Commission for Discipline Inspection means that the investigation is stronger and the shock is stronger".

　　Wu Xiaolu introduced that wang hong and Xin Wang will be interviewed again, and evidence will be obtained by signing the transcripts and verified by many parties.

　　"We will do our best to restore the facts, safeguard justice, not protect anyone who violates discipline or even law, and we will not tolerate the faculty and staff who participate in this matter and oversight in this matter." Wu Xiaolu repeatedly stressed.

　　"According to the requirements of the Ministry of Education, the identity of freshmen in colleges and universities should be reviewed by the school and submitted to the Provincial Department of Education. Graduation information will also be collected before graduation, and the identity of graduates will be checked again. " A college teacher who has been engaged in enrollment for a long time told China Youth Daily and Zhongqing Online reporter, "This kind of thing is definitely not something that a counselor can do alone."

　　The reporter noted that in March 2005, the "Regulations on the Management of Students in Ordinary Colleges and Universities" issued by the Ministry of Education clearly required that "after freshmen enter school, the school will review them in accordance with the national enrollment regulations within three months. Those who pass the re-examination shall be registered and obtained a student status. Those who fail to pass the review will be dealt with by the school according to the situation until the admission qualification is cancelled. "

　　In the latest edition of "Regulations on the Management of Students in Ordinary Colleges and Universities" published in 2017, the contents of the review have more detailed provisions, including: whether the admission procedures and procedures meet the national enrollment regulations; Whether the admission qualifications obtained are true and conform to relevant regulations; Whether I and my identity certificate are consistent with the admission notice and candidates’ files; Whether the physical and mental health status meets the requirements of applying for professional or professional physical examination, and whether it can ensure normal study and life at school; Whether the professional level of students enrolled in special types such as art and sports meets the admission requirements.

　　On December 1st, a team of four people from Heze Medical College rushed to the residence of wang hong, Jiangsu Province, and made a record of the investigation. This is also the first time that wang hong has interviewed the school staff since the incident.

　　When wang hong was asked to identify his classmates, the school provided the student files of that year. wang hong was surprised to see that after entering the school, Xin Wang’s file information had been changed to Xin Wang’s own information, including ID number, parents’ information, home address, etc., but in the name column, it was still "wang hong" and used to be called "Xin Wang".

　　In this regard, wang hong questioned the school’s "inner ghost". "Can it be said that the file information of a person when he enters school can be completely replaced after entering school?"

　　What makes wang hong feel even more strange is that according to the information inquired by Xuexin. com, the ID number on Xin Wang’s diploma is still wang hong’s own, which makes Wang Hongxin fear that his identity information may be fraudulently used.

　　Wu Xiaolu explained that from the first day of admission, the identity information of the students in the school is automatically transferred to the relevant information of the diploma, and Xin Wang really doesn’t need to know wang hong’s ID number to obtain the diploma.

　　Xin Wang is quite puzzled: "If it is transferred automatically, then all the identity information of Xin Wang during her school years should be mine. Then why did she transfer the file information to her after entering school, but the identity information on the graduation certificate is still mine?"

　　It is also strange that according to the school investigation, Xin Wang’s nurse qualification certificate was not registered according to the graduation certificate obtained by wang hong’s own ID number.

　　"Isn’t the nurse qualification certificate strictly linked to the diploma information? How did this place steal the column? " Wang hong also questioned the legality of the qualification certificate.

　　After 12 years, these questions still need to be clarified: How did Xin Wang learn about wang hong’s dropout information and identity information? Who is helping Xin Wang to make a comprehensive fraud? What kind of insider trading do they have?

　　Jiang Jiguo introduced that it was initially found out that two teachers in the school were involved, one of whom died and the other retired. How can they help Xin Wang get relevant information and help him enter school smoothly? As of December 6th, when the reporter of China Youth Daily Zhongqing Online published, the survey results of this school have not been published.

　　"The school is also the injured party. We strictly examine the qualifications of students enrolled. Some people have taken advantage of it and fake wang hong is also deceiving the school." Jiang Jiguo believes.

　　In wang hong’s view, only Xin Wang needs to stand up and confront the truth, "but the school has never disclosed any information about Xin Wang to me".

　　The school refused to provide Xin Wang’s contact number and other information to China Youth Daily and Zhongqing Online reporter on the grounds that it involved the privacy of the parties and needed Xin Wang’s consent.

　　For wang hong, she is still waiting for an apology and justice that is 12 years late.

　　Beijing, December 6 th

　　

　　BEIJING, Beijing, March 26th (Zhang Xi) On the afternoon of 26th, a press conference was held in Beijing for the release of Wu Siyao’s second full-creation album "Beijing Rihe". She threw away her iron rice bowl and insisted on making music, recalling her participation in Taiwan Province’s "Super Avenue of Stars" and "Star Conference", and said that no matter what the future, she would continue on the road of music.

　　Wu Siyao does not regret giving up the "iron rice bowl"

　　"Beijing Rihe" is Wu Siyao’s first formal solo album. The whole album continues her previous urban folk song route, taking Beijing as the main axis, and records her feelings in Beijing for seven years.

　　According to the host, Wu Siyao worked in china national radio after graduation, but she gave up this "iron rice bowl" because she loved music, and insisted on entering the music industry. In 2010, she represented star gang in the "Star Conference" and won the fifth place.

　　However, three years after the competition, she suddenly fell silent. At the press conference, Wu Siyao revealed that after the competition, she continued to concentrate on creating music, while still insisting on performing on different occasions to maintain her life and give some subsidies to her parents. Asked if she thought the original decision was too risky, she smiled indifferently and said, "In fact, when I really made up my mind to be a professional singer, I was also uneasy. The good thing is that I can still make a living by doing music-related work. This is the reality. In order to dream, you have to make concessions and compromises temporarily."

　　Referring to the title of the album "Beijing Rihe", she laughed and said that she was a young woman in literature and art, and the name came from a favorite movie "Tokyo Rihe". Since the albums are all from her hands, in the song creation part, Wu Siyao generously shared her emotional stories. She said frankly: "It may be that the feelings are rich and delicate, so each song in the album actually has some little secrets that are related or independent."

　　Huang Yunling praised the attitude of pursuing dreams.

　　At the press conference, Huang Yunling, a famous musician in Taiwan Province, also sent a blessing through the VCR. She revealed that she had known Wu Siyao for many years and appreciated her pursuit of music. "I was quite surprised when I heard this album. Her voice has not been polluted for so many years, and there are no strange habits to change her singing style and her attitude towards pursuing her dreams. As a creator, all creations come from your own heart. After going through it step by step, you will become better. "

　　A famous music professor, Shanhe, who is judging "I am a singer", is also a professional teacher of Siyao’s alma mater, Tianjin Conservatory of Music. His evaluation of students’ works is: "Listening to that quiet, gentle and carefree is also the sunshine or dew of life. Then let Siyao sing it for you. "

　　On the spot of the press conference, Shanhe specially brought Siyao’s mistress, famous dancer and host Yang Yang, and came from Tianjin on behalf of her alma mater, giving Siyao a "three good students" award, which means praising Siyao’s "good creation, good singing skills and good personality".

　　According to Reuters’s report on July 9th, Japan’s Minister of Economy, Trade and Industry, Hiroshi Shigeng, said that Japan had "not considered at all" lifting the restrictions on high-tech exports to South Korea, and the export restrictions did not violate the rules of the World Trade Organization (WTO). "Japanese sanctions have ignited the anger of the Korean people." Reuters said that tens of thousands of South Koreans launched a petition online, calling for boycotting Japanese products and traveling to Japan, and even demanding boycotting the Olympic Games to be held in Tokyo next year.

　　The game between the two sides is uncompromising.

　　Japan’s Kyodo News reported that the Japanese government strengthened the export control of three materials, namely hydrogen fluoride, fluorinated polyimide and photosensitive photoresist, to South Korea on the 4th. At the same time, the Japanese government plans to remove South Korea from the "white list country" in August.

　　According to a report by the Korea Finance Committee, since the fourth quarter of 2018, Japanese capital has accelerated its withdrawal from South Korea, and the total amount of Japanese banks’ loans in South Korea has decreased by 2.78 trillion won, which is far faster than the industry average. Recently, the constant disputes between South Korea and Japan have caused bottlenecks for Japanese companies in Korea. The Sony Korea Media Open Day, originally scheduled for the 8th, was finally cancelled due to "force majeure". Because of the accelerated withdrawal of Japanese capital, other overseas capitals took the opportunity to seize the beach. From July 1 to 11, foreign capitals except Japan purchased 430 billion won of Samsung Electronics shares and 210 billion yuan of SK Hynix shares.

　　In the face of a series of restrictions imposed by Japan, South Korean President Moon Jae in made his first response when he presided over the meeting of chief secretaries and assistant officials in Cheongwadae on the 8th, pointing out that Japan’s supply restriction measures cast a shadow over the production of Korean enterprises and urged Japan to cancel the trade restriction measures. On the 10th, Moon Jae in discussed Japanese export control measures with the presidents of 30 large Korean enterprise groups in Cheongwadae, and worked hard to formulate countermeasures.

　　Recently, the Korean stock market has fallen sharply due to Japan’s move. According to "Korea Economy" report, South Korea’s composite stock index fell 2.2% on the 8th, which is also the lowest value since May 31st. Semiconductor stocks, which were significantly affected by Japanese export control, fell sharply, with Samsung Electronics and SK Hynix falling by about 2%, and related small and medium-sized semiconductor enterprises falling by more than 10%. In addition, due to the fear of shrinking tourism to Japan, the share prices of major Korean aviation companies and tourism-related companies fell by about 5%.

　　The Korean people’s dissatisfaction with Japan has triggered calls for boycotting Japanese goods. "Japan boycott" is one of the most searched terms on Naver, the main online search engine in South Korea. As of the 5th, nearly 25,000 people signed a petition on the website of the South Korean Presidential Palace, calling for a boycott of Japanese goods. The government must respond to a petition that gets 0.2 million/200 thousand signatures in a month. "Korea Economy" said on the 8th that "boycotting Japanese goods is spreading in all directions in Korea".

　　There are reasons for the escalation of disputes.

　　Trade disputes between Korea and Japan continue to ferment. According to Yonhap News Agency, the South Korean government condemned the Japanese government’s trade retaliatory measures to restrict exports to South Korea at the meeting of the WTO Council for Trade in Goods on the 9th.

　　Bai Zhie, Ambassador of the Permanent Representative of South Korea in Geneva, said at the meeting that Japan’s export control to South Korea was an economic retaliatory measure for political purposes. Japan denies violating WTO rules. Ichihara Junichi, Ambassador of the Permanent Representative of Japan in Geneva, said that the move was not to control exports, but for national security reasons. Next, the South Korean government will once again put forward its views on relevant issues at the meeting of the WTO General Council on 23-24.

　　Why is the confrontation between Japan and South Korea so fierce?

　　Reuters believes that one of the direct factors of Japan’s export control to South Korea is dissatisfaction with the Korean court’s decision that Japanese companies imposed labor compensation during World War II. "Tracing back to the source, the root of the Japan-South Korea issue lies in the unresolved historical issues."

　　In an interview with this newspaper, Lu Yaodong, director of the Diplomatic Research Office of the Japanese Institute of Chinese Academy of Social Sciences, said that on August 22, 1910, the entire Korean peninsula became a Japanese colony. During the colonial period, Japan recruited laborers in Han Guoqiang, forcing Korean women to become "comfort women" in World War II, which triggered the hatred of Korean people against Japan. When park geun-hye came to power in 2015, he signed the Korea-Japan Comfort Women Agreement with Japan. The Japanese government consortium provided funds to support the victims of Japanese "comfort women" and carried out the work of restoring their reputation and dignity and psychological counseling. However, what the Korean people really want is the deep introspection of the Japanese government. After Moon Jae in became president, the South Korean government dissolved the "comfort women" foundation established under this agreement in 2018. Japan is seriously dissatisfied with this.

　　"Japan will hold Senate elections this year, which can be said to be crucial for Abe’s constitutional amendment. If Abe’s party can get more than two-thirds of the seats, he will have the possibility of amending the constitution. " Liu Jiangyong, a professor at the Tsinghua University Institute of International Relations, explained to this newspaper another reason why Japan-ROK relations were cold. He said, "What’s more, the South Korean government advocates that the confrontation between North and South Moon Jae in should be eliminated and a peace mechanism should be established on the Korean Peninsula. This is contrary to the wishes of the Abe government, so the Abe government put pressure on South Korea to adopt a tough policy toward North Korea. Such different demands have made the opposition between the two sides increasingly obvious. "

　　Economic chaos is no good.

　　As two countries with strong economic strength in Northeast Asia and even in the world, Japan and South Korea are in direct conflict in the economic and trade field, which is bound to bring negative effects to Northeast Asia and even the world. According to Yonhap News Agency’s report on July 8th, Moon Jae in pointed out that it is absolutely undesirable for South Korea and Japan to fall into a vicious circle of tit for tat. He warned that Japan’s emotional economic retaliation against judicial affairs risked turning into a zero-sum game between Korea and Japan.

　　Liu Jiangyong said: "In 2019, South Korea lowered its economic growth expectations because of sluggish exports and investment. In June this year, South Korea’s export volume was about US$ 44.18 billion, a year-on-year decrease of 13.5%, which has been declining for seven consecutive months. This time, Japan’s restrictions on South Korea will have a serious impact on South Korea’s related semiconductor manufacturing industry. The Japanese government wants to restrict the export of Japanese-made fluorinated polyimides and photoresists to South Korea, and the global market share is as high as 90%. South Korea has always relied on Japanese components, materials and technology to develop its own semiconductor and display industries. It is not possible to get rid of dependence overnight. Of course, this will also have an impact on Japanese supplier companies. According to statistics, in 2018, Japanese companies imported related products from South Korea to reach 2.289 billion US dollars. Once South Korea’s production is delayed due to raw material control, Japanese companies will also face the risk of supply interruption. This is negative for the economic development of both sides. "

　　The Nikkei Asian Review said that this is a bad omen for East Asia at a time when the world is facing increasing risks.

　　Liu Jiangyong said: "The escalation of the dispute between South Korea and Japan will damage the cooperation and opening up environment in East Asia. The relationship between South Korea and Japan is not harmonious, and the promotion of China-Japan-Korea Free Trade Agreement in Northeast Asia is in trouble. Japan’s unilateral sanctions similar to those of the United States have undoubtedly undermined the rules of bilateral and multilateral economic and trade exchanges among East Asian countries. This is also detrimental to Japan’s international image. "

　　Nowadays, the tide of globalization is unstoppable. If South Korea and Japan cannot reconcile, there will be no winner in the end. Liu Jiangyong analyzed: "In the short term, neither Korea nor Japan will make concessions easily, and the dispute between the two sides is difficult to cool down. But there is a high probability that the relationship will not enter a deadlock. In 2020, Japan is about to usher in the Tokyo Olympic Games. Japan hopes that the Olympic Games will be held in a peaceful atmosphere, so it is more possible for South Korea and Japan to conduct dialogue and consultation. "

　　How the contradictions and disputes between Japan and South Korea will end is of concern. Lu Yaodong said, "The Korean government is trying its best to solve the current dilemma. One is to appeal to the World Trade Organization, and the other is to increase relevant investment to achieve product substitution. However, to fundamentally solve the long-standing disputes between Japan and South Korea, we must face historical problems, and historical contradictions are extremely difficult to resolve. The Korean people believe that Japan has still not fully acknowledged the crimes committed during its colonial rule on the Korean Peninsula, demanding that Japan face up to history, reflect deeply, apologize sincerely and openly, and meet the compensation requirements.
