The game is best of three games, five players, three players in the front row and two players in the back row. In the first game and the deciding game, both sides draw lots to decide the right to serve, and in the second game, the other side serves.
When the server serves, both players must stand in two rows. If the server wins a goal, the player in the next round will continue to serve, and it is not allowed to serve continuously.
The server must serve within five seconds after the referee blows the whistle. If the ball is thrown and the server fails to hit the ball, the referee will blow the whistle again and continue to serve. If the server serves without the referee's whistle, the service is invalid. If the service is repeated, the opponent will not be awarded a score and a foul will be awarded for the second time. It is effective for the server to hit the ball anywhere on the opponent's court.
Foul rules:
It is not a foul for a player to cross the center line with one foot or both feet, but it is a foul if he touches or influences the other side.
Any player can only attack and smash the ball on the net after two meters (stepping on the line).
Blocking is not a touch, but you can also hit the ball to the opponent's court three times.
When the opponent serves, the front row players are not allowed to hit the ball or block the ball with one hand.
There are six substitutions in each game, so the suspension is cancelled.
Each team hits the ball three times at most (excluding blocking) and returns the ball to the other team's court through the net. A player may not hit the ball twice in a row.
Any part of the body can touch the ball. As long as the player doesn't catch the ball and hit it into the opponent's area, it's not a foul.
