match

The hockey game is played between two teams, with 1 1 players. The purpose of each team is to hit the ball into the opponent's goal. The game is divided into two halves, 35 minutes each, and the side with more goals wins.

Except the goalkeeper, other players can only hit the ball with sticks. If they deliberately hit the ball with their feet or any other part of their bodies, they will be punished. The left side of the wooden hook bat is flat and the right side is convex. Players can only hit the ball with one side of the plane. The goalkeeper can use any part of his body to stop the goal from scoring in the shooting area.

Game start

At the beginning of the game, the captains of both sides flipped a coin. The winner chooses to start the offensive end, and the other side kicks off at half-time. In the second half, the two sides exchanged venues, and the side that didn't kick off in the first half kicked off at half time.

At the kick-off, the players of both sides will hit the ball at least 1 m away from the half-time end point at their own half-court. Then the kickoff side tried to attack the ball to the opponent's goal, and the defender tried his best to break the ball and turn to attack. After the goal is scored, the losing side should kick off from the midfield, and kick off from the midfield every time in stoppage time.

The game continues.

If the ball is hit off the sideline, the opponent will hit the ball at his teammate and start the game again. If the ball is hit out of the baseline by the attacker, the defender will hit the ball and start the game again.

When both sides foul at the same time, the ball is shot into the player's clothes, or the game is interrupted due to the player's injury or other reasons, the game should be restarted by fighting for the ball. The position of the ball is chosen by the referee, but the distance from the end line should be at least 14. Six meters away. The ball is placed between one player on each side, and the two players alternately hit the ground and the other bat three times before hitting the ball. Other players must stand 5 meters away when grabbing the ball.

Long corner kick and near corner kick (also called punitive corner kick)

If the defending player unconsciously hits the ball out of his own end line, he will be awarded a long corner kick, that is, the attacking player will serve at a distance of 5 meters from the corner flag.

If the defensive player deliberately hits the ball out of his own end line, he will be awarded a short corner kick, that is, the attacking player will serve a free kick at the end line about 9 meters away from the nearest post and give it to his teammate just outside the shooting area to form a shot. The defender can have five players standing behind the finish line, including the goalkeeper. As long as the attackers kick off, they can attack immediately.

make a penalty shot

When the defender uses a deliberate foul in the shooting area to stop the goal or the attacker scores, the attacker is awarded a penalty. Inadvertent fouls in the shooting area can also be awarded a penalty.

score

Dangerous action

Players are usually not allowed to hit the ball in the air except shooting. It is up to the referee to judge the danger caused by the ball rising above the ground.

block

Unlike many sports, in hockey, players are not allowed to protect the ball with their bodies or bats or hinder their opponents from hitting the ball. Doing so or physically blocking the opponent is a blocking foul.

Other rules

If the goalkeeper presses the ball, it can be regarded as obstruction of foul. If a player intentionally fouls, misbehaves or has dangerous actions, he can be given a warning (green card), suspended for 5 minutes (yellow card) or expelled (red card). The replaced player can re-enter the game. The game was presided over by two referees, who were responsible for their own half-court decisions.
