Several months later, however, in winter 386, Murong Sheng warned Murong Rou and Murong Hui that, because of their status as Murong Chui's family, they were being suspected by Murong Yong (a distant cousin). At his urging, the three of them fled back to Later Yan. (His observations turned out to be astute, as a year later, Murong Yong had all descendants of Murong Chui and the Former Yan emperor Murong Jun (Murong Chui's older brother) remaining in his state slaughtered.) It took several months for them to reach the Later Yan capital Zhongshan (中山, in modern Baoding, Hebei). Murong Chui was very pleased at their arrival and declared a general pardon to celebrate. When Murong Chui asked Murong Sheng how things were in Zhangzi, Murong Sheng, at age 14, told him that Western Yan was in a state of disturbance and that Murong Chui, as long as he was able to rule his state will, that when he got ready to attack Western Yan, Murong Yong's soldiers would desert him. Murong Chui created him the Duke of Changle.
