The Paris Olympic Games will be held in 2024, and its preparation cycle has already begun. Not long ago, the General Administration of Sport of the People's Republic of China organized the supervision work of preparing for the Paris Olympic Games. During the supervision process, Xie Minhao, a member of the National Committee of the Chinese People's Political Consultative Conference, focused on the short board of China's competitive sports - collective ball games. Surprisingly, the biggest appeal of the players in the collective ball games is to continue to study. Xie Minhao put this call into this year's proposal. He learned from the research that in the past 20 years since the establishment of the postgraduate championship class of Beijing Sport University, there have been no other group ball players except the female volleyball players. "It is suggested to adjust the admission conditions of the champion graduate class in a timely manner to accelerate the cultivation of complex high-end competitive sports talents in the collective ball games." He wrote in the proposal, which will help to rapidly improve the level of the collective ball games, complement the weaknesses of China's competitive sports, and promote the extensive development of the collective ball games in the national fitness activities. In Xie Minhao's view, the biggest gain of serving as a member of the National Committee of the Chinese People's Political Consultative Conference (CPPCC) is to be able to offer advice and suggestions for sports power. Focusing on issues such as sports and health, integration of sports and medicine, he has submitted four proposals, which have received responses from relevant national ministries and commissions. Not long ago, Xie Minhao just completed the special closing defense of the national key research and development plan "Science and Technology Winter Olympics". In the 2022 Beijing Winter Olympic Games, the Chinese delegation achieved an impressive record of 9 gold, 4 silver and 2 copper. "Gu Ailing, Su Yiming, Gao Tingyu and other gold medal winners have the support of our nutritionists and rehabilitators behind them." Speaking of more than two years of winter Olympic security services, Xie Minhao, as the project leader of the "Research and Application of Scientific Nutrition Intelligent System and Injury Prevention and Control System for Winter Athletes" special project of the "Science and Technology Winter Olympics", is full of pride. By hosting the Beijing Winter Olympics, China has achieved the goal of "driving 300 million people to participate in ice and snow sports". At the 2022 National Two Sessions, Xie Minhao proposed that we should make good use of the heritage of the Beijing Winter Olympics and make the national fitness become a common practice. In his view, "300 million people participating in ice and snow sports" is one of the most important legacy achievements of the Beijing Winter Olympic Games, laying a solid foundation for further popularization and promotion of ice and snow sports. At the beginning of February this year, "a series of activities to commemorate the first anniversary of the successful holding of the 2022 Beijing Winter Olympic Games" was launched, and the venues of the Winter Olympic Games were fully open to the public during the activities; The National 2022 "National Fitness Day" theme demonstration activity and the launching ceremony of the "National Fitness Day" theme activity in Hebei Province were held at the "Snow Ruyi" National Ski Jump Center in Chongli District, Zhangjiakou City... The wonderful end of the Beijing Winter Olympics is also a new beginning of the use of the Winter Olympics heritage. As early as during the two sessions in 2018, Xie Minhao proposed to actively deal with sports injuries in the national fitness. He estimated that 300 million people participated in ice and snow sports, and at least 300000 people might suffer from sports injuries according to the probability of 1 in 1000. "Before the Beijing Winter Olympics, people often fell on the snow field, and the emergency treatment measures were not effective." He actively sought countermeasures and suggested in the proposal that indoor and outdoor sports venues and training bases should build medical facilities to provide professional on-site treatment of sports injuries. During the Beijing Winter Olympic Games, Xie Minhao also proposed that
