Emperor Tianshun, Muzong of the Liao, taboo name Jing, barbarian name Shulü, later changed to Ming; the eldest son of Taizong. Earlier, when Taizong attacked the Shi-Jin dynasty, he left the Emperor behind to attend Empress Dowager Shulü. When Taizong passed away, the generals established Shizong. When Shizong was murdered, the generals welcomed the Emperor to ascend the throne; he entered Youzhou from Huoshendian. The Emperor was young, fond of amusement, and did not attend to state affairs. Every night he drank heavily, sleeping only at dawn and rising at midday; the people of the state called him the "Sleeping King". He reigned for eighteen years.
