The editor of the game
A game should use best of three, best of five or best of seven.
A game should be played continuously, but between games, any athlete has the right to ask for a rest time of no more than one minute.
Selection and editing of direction
Serving, receiving and the choice of one's own side should be decided by drawing lots. The winner can choose to serve or receive the service first, or he can choose to be on one side first.
When one player chooses to serve or receive the service first, or choose to stand aside first, the other player should have another choice.
After each score of 2 points, the receiver becomes the server, and so on, until the end of the game, or until the scores of both sides reach 10 or the rotation service method is implemented. At this time, the order of serving and receiving remains unchanged, but each person only serves one point in turn.
In the first game of doubles, the server decides to start, and then the receiver decides to take it first. In the next game, after the first starter is confirmed, the first receiver should be the player who served 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.
In one game, one player in one direction will switch to the other direction in the next game. In the deciding game, when one side scores five points first, the two sides have to switch directions.
Error editing direction.
Once the referee finds that the order of serving and receiving is wrong, he should immediately suspend the game and serve or receive the service according to the order established at the beginning of the game and the score on the field. In doubles, when mistakes are found, they should be corrected in the order established by the side with the right to serve first, and the game will continue.
Once the referee finds that the players should exchange places but not exchange places, he should immediately suspend the game and correct it according to the correct position that the players should stand at the beginning of the game before continuing the game.
In any case, all the scores before the error is found are valid.
Rotating service editing
If a game is still not over after 10 minutes (except when both sides scored at least 9 points), or at any time before that, at the request of athletes from both sides, the rotation service method should be implemented. [7]
When the ball is still in the game, the referee should immediately suspend the game. The suspended server serves and continues the game.
At that time, the ball was not in the game state, and the receiver of the previous round had to serve and continue the game.
After that, each player takes turns to serve one point until the end of the game. If the receiver makes 13 legal counterattacks, the receiver gets 1 point.
Once the service change method is implemented, the rest of the game must continue to be implemented until the end of the game.
