慕容沖
Meanwhile, Murong Hong advanced on Chang'an, and he was joined by another brother, Murong Chong. He demanded that Fu Jian escort Murong Wei to him, and Murong Wei, while pledging allegiance to Fu Jian, secretly send messengers to Murong Hong urging him to attack Chang'an, although Murong Hong was then murdered by his own generals and replaced with Murong Chong, who claimed the title of crown prince. Meanwhile, Fu Jian himself led an army against Yao, but was unsuccessful. Fu Jian's son Fu Hui () the Duke of Pingyuan then abandoned Luoyang to come to Chang'an's aid, and all of the eastern empire was lost except for Yecheng. Meanwhile, Jin also launched campaigns, and would recapture the modern Chongqing, Sichuan, and southern Shaanxi region by early 385, as well as capturing much of the Former Qin territory south of the Yellow River, although Jin forces under Xie Xuan would at times be in temporary alliance with Fu Pi against Later Yan as well.
