Hello, landlord. The details are as follows. Grab the cards twice, three pairs each time, and then jump the cards. It's just 6+6+2/1. Among them, the first six cards are displayed, and all the cards are played according to the cards displayed in front of the door. Hu card method: if there are six unrelated cards in front of the door, you must play one of them, and then just five cards, just enough to Hu. For example, the east, west, ten thousand, forty thousand, and five cakes are shown in front of the door. Now there are six unrelated cards in front of the door, which can be regarded as six matchups. If you want to play a wild card, you must beat one of them (which can be regarded as a fly one). Then there are five cards left in front of the door, and the cards in your hand are the matchups in front of the door. If the east, west, ten thousand, twenty thousand, five cakes and three pieces come out in front of the door, there are five pieces of cards in front of the door, then the cards in your hand should be played according to the cards in front of the door, instead of flying cards; If there is something easier to play in your hand, deliberately choose a card in front of the door.
