Soon, he was promoted to a "jiedushi" (military governor), controlling most of the military power under Chai Rong. Nevertheless, he still had two rivals – Zhang Yongde (Guo Wei's son-in-law) and Li Chongjin (Guo Wei's nephew). In 959, after a trap set by Zhao Kuangyin, Zhang Yongde was demoted.

As a result, Zhao Kuangyin was able to use his influence to transfer Li Chongjin to Yang Prefecture as a "jiedushi".
