What is the general way for two people to cheat and play mahjong?

When two people play cards together, they will also ask for cooperation. These methods can be adjusted in the following ways:

First of all, we should exchange information and know what cards the other party has, what cards to touch, what cards to touch, etc ... There are only the following modes of communication:

1. It is mutually agreed to convert the name of each mahjong card into a word, which is brought into it through dialect everyday language. The jargon is also called 27 clear words and Zi Ling.

2. By designing each body movement into a card, the movements need to be hidden and routine.

3. Each card is agreed by the position and posture of the hand.

4. The information of each card is transmitted by stepping on the light and heavy feet and drawing cards on the table.

2. What cards do I need to touch on one side? The opponent sent it to him to touch the cards. After one side draws cards and draws cards, the other side turns to attack. In terms of probability, there are 50% more collaborators than you, and the probability of winning is twice that of you.

3. You can also play cards, pass cards and other tricks, so that the other side can touch Hu cards (called martial arts field in jargon). .......
