Table tennis is a popular sport with its own specific rules. The following are the rules of table tennis.

Table tennis games are usually played between two players or two teams. The object of the game is to score points by hitting the ball over the opponent's net so that the opponent cannot hit the ball back. The winner of the game is the player or team who reaches the designated points first. Usually, games are played with an odd score, such as 3 or 5.

The rules of table tennis include the following aspects:

1. Table size and height: Table tennis uses tables of specific sizes and heights. The length of the table is 2.74 meters and the width is 1.525 meters. The height of the table is 76 cm.

2. Rackets: Players need to use specific table tennis rackets to hit the ball. A table tennis racket has a wooden base and a rubber blade. Rubber sheets can have different thicknesses and friction levels.

3. Serve: At the beginning of the game, one player throws the ball into the opponent's court by serving. The rules of the serve include placing the ball in the palm of your hand and throwing it up from the back end of the platform, then hitting it with your racket so that it goes over the net and lands in the opponent's court. The serve must be hit once before the opponent can hit the ball back.

4. Return the ball: Players must try their best to hit the opponent's return ball back into the opponent's court. The return can be a volley, attack or change of shot. Players can use various techniques and tactics to gain an advantage during the game.

5. Scoring: Players score by preventing the opponent from returning the ball or allowing the ball to touch down during the game. When the opponent is unable to return the ball or touch the ball to the ground, the server will receive a point and then serve in rotation.

6. Change the right to serve: After each round, the server and receiver will exchange positions. Each player or team may only use the right to serve once in the same round.

7. Limited rules: There are some limited rules in table tennis competitions to ensure the fairness and smooth progress of the competition. For example, the serve must be thrown from behind the palm of the hand, the racket must not touch the table or net, the ball must pass over the net from the top of the table, etc.

The rules of table tennis can vary depending on the level and type of competition. For professional competitions, there are stricter rules and systems. However, the above rules are the most basic and common rules in table tennis. These rules ensure the fairness of the competition and also make the competition more interesting and challenging. Whether you are a professional player or an amateur, you should familiarize yourself with these rules and abide by them.
