What are the rules of badminton.

1. Badminton serving rules
1. Regardless of singles and doubles, you need to follow the diagonal line to receive the ball (see the ** behind), the server and the receiver need to be in the specified area, and the server must touch the ground with both feet when serving, and cannot step on the line.
2. When serving, the position of the ball is required to be lower than the waist and wrist of the server, so you can't throw the ball and "smash" directly.
3. The server has only one chance to serve, and the ball touches the server's racket or falls to the ground to end the serve (but everyone will take care of the novices in the usual game).
4. In doubles, there is no restriction on the position of the server and the teammate who receives the player, you can stand on the same side, or you can stand on both sides separately.
Doubles: Serve in the right half when the score is even, and serve in the left half when the score is odd (same as in singles). The winning side serves as the serving side for the next round. The two players switch positions when the serving side scores, otherwise the positions remain the same.
2. Scoring and side swapping
1. Scoring. Generally, it is calculated according to the 21-point system, and the winner is determined by 3 games and 2 wins; Winning a goal counts as 1 point, and the first side to score 21 points wins a game; If it is 20 draws, the side that scores 2 points in a row wins; Hit up to 30 points, and the first side to score 30 points wins; The next game is opened by the winner of the previous game.
2. Change sides. After the first game, the two sides switched sides; If the score is 1:1 after the second game, the two sides will switch sides; When the lead reached 11 points in the third game, the two sides switched sides.

The rules of badminton singles are as follows:
1. The serve should be outside the service line, not stepping on the line, wiping the net and crossing the service line, and it is valid if it is not out of bounds.
3. The serve cannot be over the waist, and the hitting point cannot be above the hand and waist, otherwise the foul will be counted and the opponent will score directly.
4. No part of the body can touch the ball, and can only hit the ball with a racket.
5. In case the smash and other return balls hit the opponent, it is not considered a foul (you can't hit people specifically, which is detrimental to sportsmanship).
6. At the beginning of the game, the serve is in the right half, and then you will stand according to your score (the score is odd or the left half is the left half, and the score is even).
7. The overall situation is a best-of-three system, each small game is 21 points, who reaches 21 points first, and leads the opponent by two points, calculates the win, and either side of the two sides gets 11 points first to exchange venues. If there is a situation of 21:20, the score will be delayed, and whoever leads by 2 points first will win, otherwise it will depend on who gets 30 points first, and the first to arrive wins.
Badminton Doubles Rules:
1. As in singles, when the serving side scores an even number, the serving side serves in the right half. When the serving side scores an odd number, the serve is played in the left half.
2. If the serving side scores one point, then the serving side will continue to serve in the next round, and the serving player will remain the same.
3. If the receiving side scores one point, then the next round becomes the serving side.
4. If and only if the serving side scores, the two players on the serving side exchange the left and right halves.
First, Cost Variance = Actual Cost - Planned Cost.

Recently, I read a book "Harvard Girl Liu Yiting", which wrote that it was the mother and stepfather who educated their daughters before. Including stimulating children's interest in active learning, teaching the truth of being a human being through examples, etc. The requirements for parents in the book are also that it seems that a small story is carefully selected, and through storytelling, filial piety is buried to know the history of the present and the outside. >>>More
The differences between domestic iron kettles and Japanese iron kettles are: 1There is too little culture on the Japanese iron kettle, the land determines its cultural connotation, China is broad and profound, and the iron kettle production history is the originator, although there has been a period of interruption in the production of iron kettle, but in modern times has caught up with Japan 2 >>>More
1.Pre-tee rules. The server should stand in the area behind the end line, between the midpoint and the putative extension of the sideline, toss the ball in any direction in the air with his hand, and hits the ball with a racket before the ball touches the ground (players who can only use one hand can throw the ball with a racket). >>>More
