Hello, landlord, if you only have two sets of cards left in your hand, but you have to play cards, you can first play a card to hold the four you need. When you touch a card, you will play it directly, deliberately delaying time to consume your patience. After the next split, you can play other cards, so as to achieve the purpose of card deduction. For example, when you leave home to make a manor, after you leave home to start, there are nine pieces of cards, and you just have a pile of cards in your hand. Since there is no trump card, it is your turn to touch the cards. When the cards hit the middle game, you can find that you have touched ten thousand, and you can do everything in one word..
