Wang Chuzhi
About two years later, in 921, Wang Du seized control of the circuit from his father Wang Chuzhi in a coup. As one of Wang Du's close associates, He Shaowei (), had previous disputes with Liu Xuan, he made false accusations against Liu Xuan, and Wang Du killed Liu Xuan. Liu Xu fled the circuit, and took up residence at Cang Prefecture (滄州, in modern Cangzhou, Hebei), in Jin territory. The military governor of Henghai Circuit (橫海, headquartered at Cang Prefecture), Li Cunshen, invited him to serve as secretary.
