In 380, Fu Jiān recalled Fu Rong, who had served as the viceroy over the eastern provinces (the former territory of Former Yan, which Former Qin destroyed in 370), back to the capital Chang'an to serve as prime minister in place of the capable Wang Meng, who died in 375. Fu Pi was made the viceroy of the eastern provinces to replace Fu Rong. As Fu Jiān, that year, also implemented a plan to distribute his Di people to various regions of the empire, a substantial number of Di soldiers and their families accompanied Fu Pi to his command post at Yecheng.
