AD is the local point.
In the following cases, the opponent will be awarded a 1-point victory:
1. When the server makes two consecutive service errors or foot errors.
2. When the receiver hits the ball with a racket before the ball hits the ground, or when the ball touches his body and the clothes he is wearing.
3. When the ball fails to return the net before it lands for the second time.
4. When the return touch touches the ground, fixed objects or other objects outside the boundaries of the opponent's court area.
5. When you fail to return the ball in the air.
6. During the game, the batsman deliberately drags or catches the ball with the racket, or deliberately touches the ball more than once with the racket.
7. During the "live ball", the player's body, racket (whether held in the hand or not) or other objects worn by the player touch the net, net post, singles pillar, rope or wire rope, center belt, white cloth on the edge of the net or the ground within the opponent's court area.
8. Fight back against the air ball that has not yet crossed the net (over-the-net shot).
9. Except for rackets held in hands (whether one-handed or two-handed), the player's body or worn object touches the ball.
10. When throwing a racket to hit the ball.
11. During the game, the player deliberately changes the shape of his racket.
These three numbers are by no means arbitrary. A man named Jean Gosling thought that these three numbers must have been the units of measurement that those who played tennis at that time were familiar with or used, and that they were derived from the astronomical sextant. The sextant is the same as 1 6 circles, with a total of 60 degrees, and every minute and 60 seconds.
At that time, there were 4 points per game in a tennis game, and 4 15 points were one degree, just like 4 15 degrees constituted 1 6 circles, and 15 was used as the base to calculate the gain and loss of each point. As for the change of 45 to 40, it is for the sake of the simplicity of the pronunciation. In the early days of tennis, there were four games per set, and each game had four points, but in the early 17th century, it was changed to six games per set, and this rule has not changed to this day.

It depends on whether you have a SLR or a double SLR, I personally use a SLR, and I have to coach Gao Lei, who is a former national team. I can only tell you about the DSLR.
