I remember a game, throwing sandbags.

1. There are 4 people in each team, male or female, throwing sandbags at both ends and avoiding in the middle.

2. Draw lots to decide the opponent before the game, and toss a coin to decide whether to throw or pick up sandbags first.

3. Each class lasts for 3 minutes, and the whole game lasts for 7 minutes, of which 1 minute is the rest time.

Every game needs timekeepers and scorers to record the time and scores of the game.

5. The sandbag throwing group scored 1, and the sandbag receiving group scored 1. If the scores are the same, judge the winner by time and knock down the opponent's 1 player as soon as possible.

6. The competition adopts the elimination system.
