Water Margin 108 How do heroes correspond to mahjong tiles?

Mahjong cards are based on 108 cards, which respectively represent 108 heroes in Water Margin. For example, the "Nine Dragons" in the card means the historical process of "Nine Dragons", and the "Two Dragons" means "Calling Tingzhuo on Two Sides", "One Cake" and "Black Whirlwind" Li Kui jy ... The reason why it is divided into three is to take the homonym of the inventor Wan C's article. There are four cards in each category from one to nine, namely 10000 to 90000, one cake to nine cakes, and one to nine, which is exactly 108. On this basis, considering that 108 heroes come from five directions: east, west, south, north and middle, we add four cards in each of these five directions, which makes 20 cards. There are poor people and rich gentry among these brave people, so they call poverty "white" (board) and hide wealth "rich" (wealth). In this way, add the words "white" and "send" and add 4 cards each, making a total of 8 cards, which constitutes the whole deck 136.
