How to set who is the dealer at the beginning of mahjong?

At the beginning of mahjong, the position of the dealer will be set by rolling the dice:

For example, a person sitting in the "east" position rolls a dice and starts to calculate the position counterclockwise. If the number of points is 7, then count down in turn, 1 is east, 2 is north, 3 is west, 4 is south, and then after a circle, 5 is east, 6 is north and 7 is west. Then, the banker's position is in the west.

The dealer rolls the dice, and the points obtained by the sum of the three dice are the 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.
