Murong Jun
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 (266–420). 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.
