It's simple. Just count your fingers. The password you said is the sum of the indexes of your two hands. For example, if he hits one (that is, one finger), you hit two (two fingers), and count at the same time, he says two, and you say three (that should be played at the same time). If you are right, you will win, and if you say the same, you will have another game.

Moreover, when rowing, one person is only allowed to use the fingers of one hand, so that two people's hands (the hand with five fingers in one hand) can form a number from 0 to 10.

Your thumb is 1 up, thumb and middle finger are extended, other palms are 2, thumb, index finger and middle finger are extended, other palms are 3, only index finger is 4, five fingers are extended, and fist is 0.

As for the password, it varies from place to place, in fact, as long as the first word is a number.

0-Bao (it seems to be),1-(I forgot), 2-Brothers are good, 3-Samsung shines brilliantly, 4-Four happiness and wealth, 5-Five champions, 6-666, 7-seven Joe, 8-eight horses, and so on.

There is also a popular night, when two people share the same bed, groping around in the middle of the night, covering their lives, walking-,riding-,picking-,very happy. (It's all some people's imagination)
