Team competition:
Men's team competition:
Choose three players and a team leader from a team (contestants or other full-time staff). Before the game, the captains of both sides should draw lots to decide the choice of A, B, C and X, Y and Z, and submit a team list to the referee, and each player should be assigned a letter.
The current competition order: the first A-X; The second game b-y; Game 3, C-Z, Game 4, A-Y, Game 5, B-X X X, each game is the best of three games. When a team wins three individual games, the game should be a draw.
Women's team competition:

The competition order of this year's women's team competition is: the first A-X; The second game b-y; The third game is C-Z; Game 4 a-y, game 5 B-X X
Methods of competition:
There are two common methods in table tennis: single round robin and elimination. If these two methods are combined, it is called mixed system. The choice of competition mode depends on the competition purpose, venue, number of teams (people) and other conditions.
First, the single round robin:
Teams or athletes take turns to compete once, which is called single round robin. This method can make the participating teams or athletes have the opportunity to participate in the competition, and can determine the names of the teams or athletes more accurately.
However, the number of single round robin is large, the competition time is long, and more venues and equipment are needed, so the number of teams or people participating in single round robin should not be too large, otherwise group round robin should be adopted.
(a) the calculation method of single round robin ranking:
According to the international competition rules, 2 points will be scored if you win a game, 1 point will be scored if you lose a game, and 0 point will be scored if you don't play or finish the game. The group ranking will be determined by stages according to the games obtained. If two or more teams in a group have the same score, their relevant rankings should be determined according to the results of their corresponding games. First of all, the score of the game between them will be calculated, and then the winning-losing ratio of individual competition (team competition), the number of games and points will be calculated as needed.
(2) Group round robin:
Although the single round robin can correctly arrange the ranking of each team (or person), it is difficult to use it when there are many teams (or people), which brings difficulties to the organization and management of the competition because of the large number of players. In this case, group round robin can be used. The most commonly used arrangement method of group round robin is "snake arrangement", that is, the sequence numbers are arranged according to the strength of each team (usually according to the ranking of the last game).
The smaller the serial number, the stronger the strength, on the contrary, the weaker the strength. When grouping, the strength of each group is required to be average, that is, the serial numbers of each group are added. On the basis of "snake arrangement", some ball games divide seed teams and non-seed teams into groups by drawing lots in batches.
That is, the 1-4 team (seed team) is fixed in the 1-4 group or enters the 1-4 group by lottery; Then the numbers 5- 8, 9- 12, 13- 16 are drawn into the 1-4 group respectively. However, after the end of the grouping period, the second stage of the competition should be added and all the rankings should be discharged. There are two common methods:?
1. In the first stage, each group will be divided into four groups for group round robin. In the second stage, the first place in each group will play a single round robin and decide 1-4. The second place in each group is a group, and the fifth to eighth places are decided; And so on.
2. In the first stage, the cross race is divided into two groups for round robin. In the second stage, the top two players in each group will compete to decide the number of places such as champion, runner-up and runner-up. In this way, the 5th-8th places are decided by 3 or 4 people in each group. 5 or 6 people in each group cross to decide No.9-12; And so on.
Second, the single knockout:
Teams (or people) participating in the competition play in the arranged order. The winner enters the next round of competition, and the loser is eliminated until the champion is decided, which is called single elimination. The number of single elimination matches is relatively small, which is conducive to arranging more players to participate in the competition in a short time.
However, this method is unreasonable, incomplete and opportunistic, and some measures must be taken to overcome these defects in order to play its role in practical application.
1. Choice of digits: digits should be a power of 2. The commonly used numbers and positions in the competition are 8, 16, 32, 64, 128, 256.
2. Bypass: If the number of people participating in the competition is not equal to the number of positions, but less than the number of positions, that is, when the number of people in the first round is less than the number of positions, the position without athletes is called "bypass" position.
3. Grab the number: when the number of participants is slightly greater than the power of 2, the square number of 2 with the closest number of participants is selected as the number digit, and a few participants "grab the number". Grab the number is to play a game at the same number position first, and the winner enters the number. The position of grabbing the number is the same as that of bye-bye, and "grabbing the number" is also a round.
4. Seeds (i.e. strong players or excellent players):
1, setting the role of "seed" The method of setting "seed" players is to overcome the irrationality of single elimination. When drawing lots, the "seeds" are evenly distributed in each "area" so as to meet at last, and strive to ensure the rationality of determining the ranking of the competition.
2. The number of seeds The number of "seeds" is mainly determined according to the number of participating teams or people. Generally, a seed is set for1/6- 12 of the number of participants, that is, 6-12 players on average; At the same time, the number of "seeds" should be a power of 2, such as 2, 4, 8, 16, etc.
3. The location of the "seed" According to the regulations, the location of the "seed" should be arranged as follows:
The first seed is located at the top of the upper half;
The second seed should be arranged at the bottom of the lower half;
The third and fourth seeds should be inserted at the bottom of the upper half and the top of the lower half respectively;
The fifth to eighth seeds should enter the bottom of odd quarters and the top of even quarters respectively; If there are many seeds (9- 16), and so on (the seed position number can be found in the seed position table). In fact, the "seeds" of the knockout stage are evenly distributed in various "zones".
