In the past, the bar distance was small, so many movements such as abdominal circle, such as horse squat, could not be completed because of the increase of the bar distance. Moreover, Muxina used to be paralyzed when practicing abdominal circle movements, which was very unsafe.

Just like Kui Yuanyuan's dazzling balance beam in the popular online video, it is the most difficult to balance the movements on the wood. The only G group has never been banned, but the athletes dare not use it, which is too difficult, but this movement is also included in Deng's difficulty reserve. It cannot be said that the rules made by the referee are aimed at China. For example, the strength of American women's gymnastics team in this cycle depends on Iurcenco 900, and the difficulty is as high as 6.5. They have three high-quality 900 s, and most other teams don't have one. Only Russia can have two. Khomova is unstable, the quality of the passer's card is too poor, and the difficulty of Iurcenco 900 will be reduced in the next cycle.
