Former Yan
Murong Hui was born to Murong Bao and a concubine described as of lowly birth while Murong Bao was a low-level Former Qin official, after Murong Chui, a Former Yan prince, had sought refuge with Former Qin's emperor Fu Jiān in 369 after a dispute with Former Yan's Empress Kezuhun and regent Murong Ping, and after Former Qin had destroyed Former Yan in 370. He was therefore probably born in the Former Qin capital Chang'an, where Murong Bao served.
