Qingdan requires two sets of cards, with a total of ten card types. It is a card game where players compete for the top game and win by upgrading from 2 and playing A according to the number of points in each card type, with a large pipe and a small bomb. 

Comparing the size of cards of the same type depends on their points. The size comparison between different card types is arranged in descending order as follows: Four Heavenly Kings (four cats)>Bombs with more than five cards>Same Blossom Shun>Bombs with five cards>Bombs with four cards>Bombs with seven card types: single card, pair (such as 44), three same card (such as 666), three belt pair (such as 666+77), three consecutive pairs (such as 334455), three consecutive cards (such as 333444), and Shunzi (such as 45678, only five consecutive cards are allowed). 

The first player to finish the game is the winner (head game). If the winner wins the first and second rounds, they will be promoted by 3 levels (if the first round hits 2, then the second round hits 5 directly), if the winner wins the first and third rounds, they will be promoted by 2 levels (if the first round hits 2, then the second round hits 4), and if the first and last rounds are promoted by 1 level (if the first round hits 2, then the second round hits 3). 

The egg is played in a counterclockwise direction, and if it is not played, it can be crossed. If all pass, the person who plays the last card will receive the card in the next round. After the three players play their cards, the deck ends. 

The so-called 'borrowing the wind to play cards' refers to the situation where the partner takes over the right to play the next round when the last hand of the upstream or second round is played and the remaining players are not playing. 
Tribute and return cards, the largest card in the entire hand is paid upstream from the downstream of the upper deck (except for red heart cards, if played 2, red heart 2 cannot be paid as tribute), and the upstream chooses a card of 10 or less to return to the downstream. 

To resist tribute, if two great kings are caught downstream or below, then resist tribute. 
After playing a hand, if there are 10 or fewer cards left, the number of cards played should be reported.
