 Fang was part of this establishment, along with, among others, the fellow future chancellors Du Ruhui and Xu Jingzong.When Du was subsequently commissioned as a prefectural secretary general, Fang told Li Shimin that Du was an uncommon talent that he should do everything he could to retain, and Li Shimin thus persuaded Emperor Gaozu to allow Du to remain on his staff.It was said that Fang was capable in planning and strategizing, but not decisive in his decisions, while Du was capable in making quick and correct decisions, and they divided their strategical responsibilities while on Li Shimin's staff in that manner.
