When Zheng He went to the Western Ocean, he carved 1-9 "strips" based on cards, tooth cards and Pai Jiu, with more than 100 small pieces of wood as the brand and fleet establishment, and then carved 1-9 "barrels" according to the number of fresh water barrels loaded on the ship. Then, according to the wind direction, four wind directions "East, West, North and South" were carved. And carved 1-9 "ten thousand" with attractive money. Then take "China soldiers are imported" as the slogan. Carve a red "clock" and then carve four flower cards according to the seasons of the year. Finally, if you don't know what to carve, you won't carve anything. This is the "whiteboard"

Another way of saying it is that a man named Wan invented mahjong in the Ming Dynasty.

Because he admired the heroes of Liangshan 108, Wan improved the existing Yezi Opera and made mahjong.

For example, "Jiutiao" refers to the historical process of the Nine Dragons, "Ertiao" refers to Shuang Bian Huyanzhuo, and "Yigu" refers to the black whirlwind Li Kui jy.

Personally, it is far-fetched to say that this game was invented and improved by one person. It is very likely that a group of people have made a new game different from the old school Ye Xixi through continuous improvement. The swastika used by the Nazis may be just a symbol.
