Chu, also known as Jing and Jing Chu, was a vassal state in China during the Spring and Autumn Period and the Warring States Period. The ancestor of Chu was Mi, a famous bear. The Chu tribe, which first rose in the land of Gudanxi (now southeast of Xichuan County, Henan Province, and Danjiangkou Reservoir in Xichuan has a large number of tombs of Chu nobles), perished in the State of Qin.
