On the Origin of Sparrow Brand

Regarding the origin of mahjong, the most mainstream view is "mahjong". Mahjong tiles, also known as sparrow tiles and sparrow tiles, were originally "grain protection tiles" in Taicang, Jiangsu. According to relevant data, there used to be a royal granary in Taicang City, Jiangsu Province, which hoarded rice for the "South Grain to North Transfer Project" all the year round. Many natural birds suffer from food, and a lot of food is lost every year because of the pain of birds.

In order to reward the bird catcher and protect the grain, the officials in charge of the granary recorded the number of birds with bamboo pieces and paid them accordingly. This is Taicang's "food protection card". This card is engraved with various symbols and numbers, which can be watched and played, and can also be used as a voucher for exchanging bonuses. The games, symbols and appellations of this kind of food protection card are all related to bird catching.
