Murong Sheng
When Murong Chui rebelled against Former Qin in 384 and established Later Yan, Murong Hui was in Chang'an, then still under Former Qin control. After the last Former Yan emperor Murong Wei, then a Former Qin general, tried to rebel within the city around the new year 385, Fu Jiān ordered the Xianbei in the city killed, but Murong Hui, along with his uncle Murong Rou (慕容柔) and brother Murong Sheng, were not killed, apparently because Murong Rou had been adopted by the eunuch Song Ya (宋牙). Soon thereafter, though, Murong Rou, Murong Sheng, and Murong Hui fled Chang'an and sought refuge with Murong Wei's brother and the leader of the nascent Western Yan state, Murong Chong.
