According to the previous schedule of world sports, the Olympic year usually only has the Olympic Games, which is an important competition, including individual or team world championships, and will not be arranged in the Olympic year. However, due to the postponement of the Tokyo Olympics by one year due to the epidemic, the world sports world in 2021 is particularly busy, following the recent three major team events of badminton Sudirman Cup, Uber Cup and Thomas Cup held in a month, gymnastics, weightlifting, table tennis and other sports have also begun or are about to start, which also makes the Tokyo and Paris Olympic cycles of each event almost seamless.

The Gymnastics World Championships in Kitakyushu, Japan, is the first world competition of the Chinese gymnastics team in the Paris Olympic cycle, for gymnastics, this scoring event, each world competition is an opportunity for athletes to show in front of the referee, and before the Olympic Games, let the main players accumulate enough "refereeing edge", but also the gymnastics team in each competition must consider the problem of platooning. At this World Championships, the members of the Chinese gymnastics team participating in the Tokyo Olympics did not participate, and the basic players who went to Japan were previously selected for the Tokyo Olympics for various reasons, but they were still of the right age in the Paris cycle. Among them, Zhang Boheng and Weng Hao of the men's team, Li Shijia and Wei Xiaoyuan of the women's team have already emerged in the domestic arena in the Tokyo cycle. After regretting missing Tokyo, the performance of this World Championship has a very important impact on their future prospects.
Similar to the choice of gymnastics team, the Chinese weightlifting team recently announced the world championship list is also not a Tokyo Olympian, the male and female four-person lineup is basically based on newcomers, the most brilliant in the past, should be the women's 49 kg class Of Jiang Huihua. She was the winner of this category at the 2019 World Championships, and this year's Shaanxi National Games lost only one kilogram to Tokyo Olympic champion Hou Zhihui. On the men's side, Li Dayin, who played in the 81 kg class, is also quite interesting, because veteran Lu Xiaojun is likely to choose to retire, Li Dayin is undoubtedly a popular candidate for China's next leader in weightlifting at this advantageous level, and this World Championship is the first major test for him. Overall, the players participating in the World Championships are mostly in the position of challengers in the Tokyo Olympic cycle, and whether they can successfully challenge in the Paris cycle is the first opportunity for them to prove themselves.
Unlike gymnastics and weightlifting, which focus on training newcomers, the national table tennis team that is about to go to the World Championships has lined up a new lineup with the old. Obviously, for the first world competition in the Paris Olympic cycle, the national table tennis team, which also faces the replacement of old and new, hopes to be foolproof.
