Big four happiness, a mahjong term, is a way of neutralizing cards in mahjong. It is established when the drawing of cards includes four kinds of engravings (touching cards, dark engraving, bright stripes and dark stripes). In the national standard mahjong, it counts 88 times and is the most valuable one.
Dasixi is a special type of mahjong, which belongs to one of the national mahjong varieties. When the card face is combined, it is composed of four carved plates of four wind cards in the southeast and northwest, which can form the big four-happy card type. It should be noted that the circle wind carving, door wind carving, three wind carving, concave-convex and sum are not included in the four hi cards. In the national mahjong rules, the score of fans is divided into twelve grades, of which 88 is the highest. As one of the seven 88-fan cards, Big Four Happiness is very valuable and difficult.
Drawing difficulty
1, the probability of making up four groups of wind images is very small. Even if four winds plays, you need to have four winds's pair in your hand, and almost no one will play four winds after the third deck. From this point of view, at least nine three pairs of wind cards and one carved wind card are needed to qualify for the four happiness.
2, easy to fire. The great benefits of the four happiness are accompanied by risks. If you have been listening to (listening to) cards or even drawing cards since you entered the third year of high school, then you can play very few safety cards except four winds at this time, so it is more likely to get some guns by listening to cards at his home. If you light a gun, the four happiness will be useless.
3. The card type is too conspicuous. When your card river is short of cards and one or two wind cards are issued, players with keen sense of cards will pay attention to you. If there is a deputy dew confirmed by senior four (in this case, it must be riding alone), then basically everyone will play the absolute safety card and abandon Hu. Therefore, like the big three yuan, it is best to engrave at least one wind sign for the four happiness.
