Correlation process

Mahjong begins to touch the cards clockwise after the roll of the dice, and the roll of the dice determines the dealer, not after the play. In the national standard mahjong, the dealer rolls the dice, and the points obtained by the sum of two dice are the base of playing cards. Take the dealer as the first, count counterclockwise, and the position of the points is the card wall for opening cards.

Counting the piers with the same number of points in turn from right to left, the dealer starts to grab two cards, and the next one draws cards in clockwise order until everyone draws three cards *** 12, then the dealer jumps cards (every pier) to grab the above two cards, and others draw one card in turn. The dealer * * * has a card of 14, and everyone else has a card of 13.
