The Study of the Subrogation of the Kingdom of Shu Pre-Qin Dynasty

As the ancestors of Shu, Cancong at first lived in the northeast of Sichuan, and the Cancong Era was almost in the same period with the reign of Yellow Emperor. Then the Baiguan Era came into being. Sanxingdui culture is the Shu culture in Yufu Era, when the kingdom of Shu was already established. At the end of Shang dynasty and the beginning of Zhou dynasty, the ancient Shu entered the Duyu dynasty. It was found that the development of Shu was in a continuum, from Cancong, Baiguan, Yufu to Duyu. It was in the middle of the Spring and Autumn Period that Kaiming dynasty replaced Duyu, which was conquered by Qin in 316BC.
