汉隐帝
In 941, after Shi Jingtang overthrew Later Tang and established his state of Later Jin, Liu Zhiyuan acted as the military governor of Hedong Circuit (河東, headquartered in modern Taiyuan, Shanxi). The 10-year-old Liu Chengyou was given the title of an overseer of the circuit headquarters. In 947, after Later Jin was destroyed by the Khitan Liao dynasty, Liu Zhiyuan declared himself emperor of the new state, Later Han and Liu Chengyou was given the title of General. His older brother Liu Chengxùn was given more substantive responsibilities, including overseeing Taiyuan while Liu Zhiyuan advanced south to take over the central parts of former Later Jin territory. He became mayor of Kaifeng after Liu Zhiyuan successfully took the Later Jin capital as his own.
