Abstract: The authors probed into the following changes brought by the 11-point system to the techniques and tac-tics for table tennis, including the ball serving attack period, ball returning attack period and rally period: ball serv-ing changes in the ball serving attach period are the most important changes; ball serving means tend to be diversi-fied; follow-up moves after a ball serving attack are critically important. Initiative awareness of ball serving and re-turning is very important, while the athletes should have comprehensive ball serving and returning techniques. In the rally period, the offense and defense switching speed should be fast, and the ball landing point and ball hitting power are also important; During rally the ball landing point should vary a lot, and the awareness of attacking the opponent’s forehand area with straight line balls should be highlighted.
