Murong Chui told Fu Jiān that he was fearful that the people over the Former Yan territory would rebel, and that it would be best if he led a force to pacify the region. Fu Jiān agreed, despite opposition by Quan Yi (權翼). Murong Chui took the army and arrived at Yecheng, which was being defended by Fu Pi. They suspected each other, but each ruled out ambushing the other. When the Dingling chief Zhai Bin (翟斌) rebelled and attacked Luoyang, guarded by Fu Pi's younger brother Fu Hui (苻暉), Fu Pi ordered Murong Chui to put down Zhai's rebellion, and Fu Pi sent his assistant Fu Feilong (苻飛龍) to serve as Murong Chui's assistant. On the way to Luoyang, however, Murong Chui killed Fu Feilong and his Di soldiers and prepared to openly rebel. Meanwhile, despite his suspicions of Murong Chui, Fu Pi did not put Murong Chui's son Murong Nong and nephews Murong Kai and Murong Shao (慕容紹) under surveillance, and the three fled out of Yecheng and started a rebellion of their own.
