Xin dynasty
After Wang Mang usurped the Han throne and established the Xin dynasty, in about 15 AD he appointed Gongsun Shu the Governor of Daojiang (導江, the former Shu Commandery of Han), with its capital at Linqiong, near Chengdu. Gongsun held the position until the forces of the Gengshi Emperor overthrew the Xin dynasty in 23 AD.
