Ice hockey, also known as "ice hockey", is a highly antagonistic group ice sport, which combines skating technology with curved stick technology. In ice hockey competition, players hold clubs, wear special skates and protective equipment, slide on the ice rink with wooden boundary walls and compete for the right to the ball. Ice hockey is generally made of hard rubber. In the competition, each team played 6 players, namely 3 forwards, 2 defenders, 1 goalkeeper. Players use popsicles to hit the ball into the opponent's goal, and those who hit more than one will win. Each game is 60 minutes, divided into three rounds, and the intermission 15 minutes. If the goals of both sides are equal in the whole game, you can add 10 minutes, and if they are still equal after overtime, it will be judged as a draw.

Ice hockey originated in Canada. 1855, an ice game was popular in Kingston, Canada. Participants tied skates on their feet, held curved sticks, chased logs on the frozen lake and hit the ball into the goal. The goal system is marked with two upright wooden poles. There is no limit to the number of participants and there is no uniform regulation on the venue. This is the predecessor of modern ice hockey. By 1858, ice hockey has reached the level of popularization in Canada, and then it soon spread to Europe. 1On March 3rd, 875, Canadian Clayton held the first official ice hockey game at the Montreal ice rink. From 65438 to 0879, two professors, Robertson and Smith of McGill University in Canada, formulated the rules of the game similar to modern ice hockey.

1890, the first ice hockey organization in the world-Ontario Ice Hockey Association of Canada was announced. From 65438 to 0908, the International Ice Hockey Federation was formally established in Paris, France, and the first European Ice Hockey Competition was held in Berlin, Germany. 1920, the ice hockey game made its debut at the 7th Summer Olympic Games. 1924 when the Olympic games were divided into winter and summer, ice hockey was listed as the official event of the first winter Olympic games, and it was always limited to men.

Because of its high speed and great impact, ice hockey players should wear protective gear in the game. The four corners of the ice hockey arena are arc-shaped, with a length of 6 1 m and a width of 30 m, and walls made of wood or plastic, with a height of 1. 15 m to 1. They are 22 m around and have smooth inner walls to protect ice hockey players from accidental injuries. Because of the fierce ice hockey confrontation, the punishment for players who violate the rules is very severe. When an athlete (except the goalkeeper) commits a serious foul, he will be punished with a "big penalty", that is, he will be sent off for 5 minutes and cannot be replaced by others; Generally, a foul will be punished with a "small penalty", that is, a penalty of 3 minutes. When the foul player is punished, he must sit at the penalty spot. At this time, there will be many fewer people in the two teams on the field.
