Ping pong, badminton, volleyball, Chinese athletes can achieve good results in all three competitions, but basketball and football are not the same. It seems quite difficult to achieve a breakthrough in the short term, especially football. Table tennis, badminton and volleyball have this Commonality: Both sides of the game have their own fixed positions, and the victory or not depends on the size of the defense ability. The players in basketball and football games run all over the field, and the victory or failure basically depends on the size of the offensive ability. The characteristics of Chinese athletes' sports capabilities reflect the characteristics of the Chinese culture behind them: they are defensive, not offensive. The text is intended to explain:.
