慕容農
Fu Pi was not involved in the crushing defeat that Former Qin forces suffered at the Battle of Fei River, as he remained at Yecheng. In the aftermaths of the battle, however, the Xianbei general Murong Chui, a Former Yan prince, plotted a rebellion to reestablish Yan. In late 383, after persuading Fu Jiān to allow him to visit the eastern provinces to try to calm the people in light of the defeat at Fei River, Murong Chui arrived at Yecheng, where Murong Chui continued plotting, and where Murong Chui and Fu Pi considered ambushing each other but each decided not to do so. When, subsequently, the Dingling chieftain Zhai Bin (翟斌) rebelled and attacked Luoyang, defended by Fu Pi's brother Fu Hui (苻暉) the Duke of Pingyuan, Fu Jiān 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 (慕容楷) and Murong Shao (慕容紹) under surveillance, and the three fled out of Yecheng and started a rebellion of their own.
