Boxing play: Two participants make one hand (usually the right hand) at the same time, compare different numbers from zero to five or six by clenching their fists or extending different numbers of fingers, and shout out a password at the same time, corresponding to a number from 0 to 10. If the number represented by the shouted password is the same as the sum of the hand indexes given by the two people, it is a guess. If two people guess wrong or both guess wrong, it will be regarded as a draw, and continue to punch in and call for orders until one party guesses wrong and decides the outcome. Whoever guesses wrong will be punished for drinking.

Etiquette and taboo of fencing:

1, when guessing boxing, you can't call the number directly, but shout out an auspicious or friendly password, which is called "oral lottery".

2. At the beginning, peers usually call the two brothers first to show friendship; If there is a generational difference, the elders will call mom and dad good, and the younger generation will call their hearts good to show their love and respect. According to this rule, the first punch is a thumbs-up as a greeting, and the formal guessing begins with the second punch.

3, there is a so-called "fist never leaves the thumb", which means that in addition to small gestures, the comparison of one to five requires the participation of the thumb;

4, can't use the thumb and forefinger to compare the inverted "eight" shape;

5. Don't punch at the other person's face or body, because such a gesture is impolite;

6. Never give a zero or five at the beginning, which is impolite;

7. The punch call must be at the same time as the opponent, and the latter may be punished;

8. If you bend your fingers when you punch, or make a noise when you shout a password, you may also be punished.
