Step 1: For example, if there are three people and all other teams are more than three people, then we will compete internally first and eliminate three people from each team.
Step 2: Among the four teams, you can use stones, scissors, cloth or coin toss to decide which two teams draw lots. First, you can draw lots to decide the team's duel, and then you can decide who to send first after listening to the arrangement of the coach or captain.
Step 3: The ranking is determined by the outcome. If you win, you get one point; If you lose, you won't get a point; If you draw, you will get half a point. Finally, the ranking is determined by the score.
The fourth step: it is best to have a cameraman shoot the whole process, just like the live broadcast of NBA games; If it can be photographed, there is no clue; If the conditions are limited, then you can only ask the referee.
