How to choose a position when playing mahjong?

First, let's make sure that a certain direction is east, and then find a card in the east, south, west and north. After shuffling, everyone touches a card, and then according to the touched wind sign, the east position is set in turn, and then the seats in the south, northwest and south are set in counterclockwise order.

The positioning of the dice is also different from that of the two dice. If you roll the dice, 5634 corresponds to the four directions of southeast, northwest and northwest respectively, and 12 does not count. If the throwing points are the same, it is not counted and needs to be thrown again. If you throw two dice, 5,9 is east, 6, 10 is south, 7, 1 1 is west, and 8, 12 is north. If the number of points thrown at the back is the same as that of the previous person, it is not counted, and the latter person needs to throw it again.
