What do you think should be paid attention to when watching football matches?

When spectators enter the competition venue, they should pay attention to the rules of the venue: First, do not bring prohibited equipment and drinks into the venue. Because some strange utensils and canned drinks are likely to cause personal injury to athletes. For the safety of the stadium, the audience shall not hinder or refuse to cooperate with the safety inspection of the stadium. Second, when watching the game, don't point at the game and the performance of the players, and chatter endlessly, which will affect others to watch the game. Shouting "black ball" and "black whistle" is not satisfied with the performance of mobilization and referee, which is dissatisfaction with athletes and referees. Football is the most passionate sport in the world, and its connotation is very rich. Every fan can find what he needs in it: struggle, tactics, luck, winning or losing, hero, honor and so on. The pleasure and enjoyment it brings are incomparable to other activities. However, due to the physical collision on the court, or the referee's oversight and misjudgment, it often causes the fans' overreaction, leading to conflicts and even riots and casualties. It is very important to pay attention to the etiquette of watching the game and advocate civilized watching the game. Dress for sports competitions does not have to be like opera or concert, but also should be decent and generous, whether it is casual or sportswear. Some cheerleaders wear jerseys of the same color as their favorite teams, and some fans are ingenious and draw national flags on their faces, which will enliven the atmosphere of the game. Wearing vests, shorts, sandals, and even going to the stadium with bare arms are harmful and do not meet the requirements of public etiquette. In and out of the stadium, you can carry the commonly used items of cheerleaders, such as gongs, drums, horns, flags, cheering banners, etc., but you can't carry insulting slogans, alcoholic drinks, bottled drinks and other items explicitly prohibited by the stadium. When the two teams enter the stadium, they should be treated kindly. You shouldn't just applaud your favorite team and ignore another team.
