In the national standard mahjong, the big four happiness is composed of four pairs of wind carved (bars) [east, south, west and north]
(Not counting three wind engravings, bumping, circling wind engraving, door wind engraving, nine minutes, and missing one door. In fact, it should be at least 94 times, because it is impossible to avoid all the six times of mixing the same color and 64 times of the same word. )
The difficulty of drawing cards in senior four is relatively high, mainly for the following reasons:
1, the probability of making up four groups of wind signs is very small.
2. The cards that can do big four happiness are very good. They often do 12 times, and then they don't keep the wind cards any more. There is no idea of impacting big four happiness.
3, Xiao Sixi is "enough". The big four happiness must be in the form of collision and harmony, so you may have a straight when you haven't collected the four winds, so you choose the small four happiness that is 24 times less than the big four happiness.
4, easy to fire. The huge gains bring the same big risks. Compared with other cards, Big Four Happiness belongs to a kind that is easier to get a shot. The reason is that Big Four Happiness is mostly knocked out, so there are few hands, and it is difficult to avoid even when judging the tendency of others to listen to cards.
5, the card type is too conspicuous. The three winds that come out will be closely watched, and the senior year is rare. The big four happiness that comes out is the center of the game, and everyone can't play cards in pairs, so they can only rely on their own touch. Unless a family also has 88 draws, then because of the particularity of the big four happiness, other families will pay more attention to you, and that family's big-name draw will be easy to make peace.
