What are the etiquette for playing billiards?

1. Clothing: slippers, sports shoes and sportswear are not allowed. You can wear a T-shirt, but you must have a collar. If it is a snooker competition, you must wear a snooker vest. One is etiquette, and the other is to tighten the upper body to prevent the shirt from sagging and touching the ball.

2. It is illegal to touch the ball in any part of your body, so please take care to remove unnecessary ornaments, including necklaces and ornaments. It is best not to put anything in your pocket, otherwise it will interfere with your playing.

3. Shake hands with referees and opponents before and after the match.

4. Don't make any noise when the opponent hits the ball, don't walk around at will and don't stand on the opponent's hitting line. You can wait in your seat when your opponent hits the ball. It's a foul not to stand on the table and affect your opponent's hitting the ball.

5. Take the initiative to remind the referee that his foul behavior is the performance of a gentleman. During the game, the audience will give you applause and the opponent will respect you.

6. Any act of destroying the equipment is not allowed.
