Number of people: The number of people in each team of the two participating teams shall not exceed 1 1. Each team must have a goalkeeper. Each team can have 1-2 substitutes during the game. If it is a "friendship match", there may be less than five substitutes. With the consent of the referee, when the game is suspended, the substitute can replace the players. The head coach of each team can freely adjust the appearance and appearance of players in each game, but a team has only three substitution opportunities in a single game, and the substituted players can't play again. Substitutes can't play until they leave the field. No player is allowed to play or leave without the permission of the referee. Penalties A. For those who violate the provisions of Article (4) of this chapter, the game shall not be suspended, and all relevant players shall be warned immediately when the game becomes a dead ball. B. If the substitute player enters the field without the permission of the referee, he should stop the game and give a warning to the substitute player to leave or order him to leave according to the situation. Then the referee will drop the ball where the game was suspended and resume the game. Unless the ball was in the goal area at that time, in this case, the ball should fall on the goal area line parallel to the goal line where the ball was closest when the game stopped. C related players who violate other rules in this chapter will be warned. If the referee suspends the game to carry out the warning, the opposing team should kick an indirect free kick where the ball was at the time of suspension to resume the game. If a free kick is punished in one's own goal area, it can be executed anywhere in one's own goal area. If you punish a free kick in the opponent's goal area, it should be the nearest place when the game is suspended. It is executed on the goal zone line parallel to the goal line. D. If the rules of the game require that the list of substitute players be submitted to the referee before the game, punishment: If the player on the field violates the provisions of this chapter, unless the player has adjusted his equipment before the dead ball, he should leave the field to adjust or change his equipment after the dead ball. Players who leave the venue to adjust and exchange equipment must report to the referee before returning to the venue. After the referee checks that it meets the requirements, he can only enter the stadium if the game is a dead ball. Don't stop the game immediately when the players on the spot violate the provisions of this chapter.
