Legend of the origin of chess

China chess originated in China. Dr Joseph Needham, a famous British scholar, clearly pointed out in China's History of Science and Culture that chess is also the creation of China people.

He analyzed in detail the relationship among China ancient games, Liubo, astronomy, imagery and mathematics. He said: "Only in China, the prevalence of the theory of Yin and Yang promoted the embryonic form of chess, invented divination with astronomical nature, and then developed into a game with military significance.

The word chess first appeared in the Warring States Period. There is a special record of its shape and play in "Chu Ci Evocation": "There are six books in chess; Go hand in hand with the camp, and the road is forced; When you become a cockroach, you will seek it and you will be white. " It means that jade is equivalent to dice.

Han and Liu also recorded Zizhou's view in "Talking about the Garden Mountain": "The first step is the king of a thousand times ... Yan Dou Qi dances Zheng Nv." In other words, to persuade Meng, it is better to play chess and watch songs and dances, just like "Yan State". All these show that "chess" has become a routine activity during the Warring States period. So chess came into being before the Warring States Period.
