周世宗
After the establishment of the Later Han in 947, the Guo family's condition improved dramatically. Guo Wei became the commissioner of military affairs () in 948, and his adopted son became the left commandant for palace-gate security (). On 4 May 950, Guo was promoted to military governor of Tianxiong Command () and delegated to garrison at Weizhou (魏州; modern Linzhang County, Hebei) at the Later Han-Liao Dynasty border to prevent a possible Liao incursion. Ten days later, his adopted son was appointed Tianxiong Command's chief director of military headquarters () to follow him in Weizhou. Chai Rong — by now known as Guo Rong — was also given a nominal post of prefect of Guizhou ().
