The first round of competition will be divided into groups by drawing lots. If a person has bye, he will go straight to the next round. The winners of the first round will be regrouped and drawn from the numbers. The winner advances to the next round, and the bye group advances directly.
In a game, as long as each person serves 5 points (a ball), they will exchange the right to serve, and so on until the end of the game. The winner is the athlete who scores 1 1 in each game; However, after the scores of both sides reach 10, the one who gets 2 more points first wins. 10 after the lottery, the rotation service method will be implemented. Instead of exchanging service rights after serving five balls, each person only served 1 ball. Immediately exchange the right to serve, and the first two points will win. When a game ends or one side scores 5 points first in the deciding game, it should exchange places with the other side.
In the first game of doubles, the server determines the first server, and then the receiver determines the first receiver. In the following game, after the first server is determined, the first receiver should be the player who served for him in the previous game.
In doubles, every time the service is changed, the former server becomes the server, and the partner of the former server becomes the receiver;
The player who serves first in one game should accept the service first in the next game. In the doubles final, when one side scores 5 points first, the receiver should exchange the order of receiving the service.
