Murong Chui (Chinese: 慕容垂; 326–396), courtesy name Daoming (道明), formally Emperor Wucheng of (Later) Yan ((後)燕武成帝) was a great general of the Chinese/Xianbei state Former Yan who later became the founding emperor of Later Yan. He was a controversial figure in Chinese history, as his military abilities were plain, but as he was forced to flee Former Yan due to the jealousies of the regent Murong Ping, he was taken in and trusted by the Former Qin emperor Fu Jiān, but later betrayed him and established Later Yan, leading to a reputation of him as a traitor. Further, his reputation was damaged in that soon after his death, the Later Yan state suffered great defeats at the hands of Northern Wei Dynasty's founder Emperor Daowu (Tuoba Gui), leading to the general sense that Murong Chui contributed to the defeats by not building a sound foundation for the empire and by choosing the wrong successor.
The future Murong Chui was born in 326, while his father Murong Huang was still the heir apparent to Murong Hui the Duke of Liaodong, a vassal of Jin Dynasty (265-420). He was Murong Huang's fifth son. His mother was Consort Lan, a concubine of Murong Huang. In his youth, he greatly impressed his father with his talent, and his father, sometime after succeeding his grandfather as the Duke of Liaodong in 333, wanted to make him the heir apparent. The officials advised against the action (since the general rules of succession requires that the heir apparent be the oldest son of the wife—in this case, his older brother Murong Jun, the oldest son of Duchess Duan), and Murong Huang agreed and made Murong Jun heir apparent, but still favored him greatly and officially named him Murong Ba (慕容霸, Ba meaning hegemon). Because of this, Murong Jun was very jealous of his younger brother.
