The method is as follows:

1. First know how many tiles there are in mahjong. One person has 17 piles, each pile contains 2 tiles, so there are 136 tiles.

2. Determine the order according to the seats. Starting from the dealer in the east, roll the dice and draw cards counterclockwise according to the points.

3. After drawing the cards, the dealer has 14 cards and the remaining 13 cards, and starts playing mahjong.

4. The dealer plays the cards, and the others can perform operations such as touching, difference, listening, and Kong according to their own cards (grab a card, play a card, and keep 13 cards in hand).

5. After listening, the cards cannot be changed, and then roll the dice to find a card and use it as a treasure.

6. Finally, you can wait for the Hu card. According to your own cards, you can defeat the Hu card, hang alone, hold a treasure, etc.
