The earliest records of Chinese chess can be traced back to the Warring States Period (475BC—221BC). The early-stage Chinese chess was composed of six pieces carved out of ivory, and was therefore called “Six Boxing”. Its final form of play was fixed at the end of the Northern Song Dynasty (960AD-1127AD) after a long period of development. The chessboard is a rectangular board that is 9 lines wide by 10 lines long. Composed of marshal or general, advisors (scholar or official), civil officials (elephant or minister), military officers (chariots, horses, and cannons), and soldiers (soldiers or pawns), Chinese chess is Chinese social institution and culture in miniature. It is also one of the four most popular chess games in the world, the other three being the Chinese Weiqi, the game of chess, and shogi (or general’s chess).
