Key points of competition rules:

1. The general game is played for 7 rounds. After 7 games, the player who scored more points won. If the two teams draw after seven games, they will go into overtime until one team wins. There are generally four referees in official competitions, namely 1 ball referee and three base referees, and two line referees will be added in major competitions. Nine players from each side took part in the competition.

2. Defensive players include pitcher, receiver, first baseman, second baseman, third baseman, shortstop, left fielder, center fielder and right fielder. The attacking players hit the ball in turn according to the pre-arranged order.

3. Scoring and safety: In the game, after the batter hits the ball thrown by the other pitcher, he can't run until the ball falls on the sideline. If it falls outside the touchline, it is a foul ball, and the batter continues to hit the ball. If the hit ball is caught by the defender in the air, the batter is out directly, whether in or out of bounds. After the ball falls into the inside, the defender must quickly pick up the ball and pass it to the designated base. If the batter (or base runner who is already on base) arrives before the ball reaches the corresponding base, it is safe, otherwise he is out. If the batter reaches first base counterclockwise, he becomes a runner, then runs to second base, third base in turn, and finally runs back to home plate, he gets a point. In a game, if three players of the attacking side are out, the attack is over and the two sides exchange offense and defense. Both sides attack and defend once in a game.

4. Home Run: A home run is when the batter hits the ball directly into the outfield fence. At this time, the batter and all base runner can run back to home plate to score.
