Fu Pi
In fall 386, the Western Yan ruler Murong Yong, whose people had abandoned the Guanzhong region to head east, trying to return to their home land, requested Fu Pi to grant permission to let them through. Fu Pi refused and tried to intercept them, but suffered a major defeat, in which Wang Yong and the major general Juqu Jushizi (沮渠俱石子) were killed, and most of Fu Pi's officials and his wife Empress Yang were captured. The only general under Fu Pi who still had a strong army remaining was his cousin Fu Zuan (苻纂) the Prince of Donghai, who remained at Jinyang, but Fu Pi was suspicious of Fu Zuan's intentions and therefore did not dare to return to Jinyang, but instead headed south, wanting to make a surprise attack on Luoyang, then held by Jin. The Jin general Feng Gai (馮該) intercepted him and killed him in battle. His sons Fu Ning (苻寧) the crown prince and Fu Shou (苻壽) the Prince of Changle were captured by Jin forces but pardoned and given to their uncle Fu Hong (苻宏) -- Fu Jiān's crown prince, who had surrendered to Jin earlier. His sons Fu Yi (苻懿) the Prince of Bohai and Fu Chang (苻昶) the Prince of Jibei were escorted by an official to his distant nephew Fu Deng the Prince of Nan'an, who initially proposed making Fu Yi the emperor, but after his subordinates recommended that he take the throne himself, did so.
