Mahjong originated in China, Guangdong, Hong Kong, Macao and southern Fujian, commonly known as sparrow. It is a game and entertainment appliance invented by ancient people in China.

A small rectangle usually made of bamboo, bone or plastic with patterns or characters engraved on it. Each pair of northern mahjong is 136, and southern mahjong has eight more cards of plum, bamboo, orchid and chrysanthemum in spring, summer, autumn and winter, totaling 144.

Playing dominoes with four people is very popular in China cultural circles. In the late Ming and early Qing dynasties, while the horse brand prevailed, an entertainment device called "playing cards" was derived from the horse brand. There were 60 cards at first. When playing cards

Four people each take ten cards first, and then play cards in turn. One family plays cards, and two or even three families say at the same time that the first one to get the card wins. These items and playing methods are very similar to today's mahjong tiles. This card game is always silent in the process of playing, so it is also called silent card.
