1. Shuiguchun is not fit to continue the competition. The reason why Shuigu Junyi chose to retire is because many years of high-intensity training have left many disadvantages for Shuigu Junyi's body. Now that Shuigu Jun is getting old, his body is no longer suitable for high-intensity training and competition. After all, Shuigu Junyi has been on the court for quite a long time. It can be said that he is too old to compete and train, and retiring at this time will be of great benefit to his next life.
Second, the retirement of Shuigu Junyi can give the new generation more exercise. Shuigu Junyi chose at this time, on the one hand, his own ability and level, and there is no way to beat the new generation of table tennis players. Secondly, because Shuigu Junyi also wants to give more opportunities to the new generation and let them have more experience in the field, so as to win glory for the country in the field. After all, he has participated in many Olympic Games now. In the case that his level can't be improved, I think the purpose of his retirement is to let him. In addition, after Shuigu Jun retires, he can continue to serve the country as a coach and train table tennis players from generation to generation.
Three. To sum up, I personally think that Shuigu Junyi chose to retire because his body can't withstand such high-intensity training, so his table tennis level is getting worse and worse, and he has even begun to beat some young players. At this time, he chose to retire in order to let more young people have competition experience.
