Three consecutive engravings are three pairs of engravings connected with the same color, such as 333,444,555,000, and one color and three straight ones are three pairs of flush in the same order, such as 345,345,345,000, with the same door clear. However, the normal straight is only when the cards are fed at home, and the lettering can be touched, so the straight is more difficult.
A straight card of the same suit is divided into spades, hearts, flowers and diamonds. A straight is a set of cards (4, 5, 6, 7, 8, 9, 10, j, q, k, 1A, 2, 3, sketch and drama) arranged in order of card size. If they are all flush, compare the size of the biggest card; If the sizes are the same, compare the sizes of suits.
One theory was invented by Zhang Sui, an astronomer in the Tang Dynasty. It was originally called "Ye Zi Xi" because the card is only as big as a leaf. Ouyang Xiu, a writer in the Song Dynasty, also recorded "Ye Xixi" in the Record of Returning to the Field, which was developed from word games.
