Yan Fei was from Jibei.[2] When Cao Pi was the presumptive heir to the Cao Wei throne, Yan was one of his attendants.[2] After Cao became the emperor, Yan was appointed a Gentleman-in-Attendance of the Yellow Gates [zh], an official who served at the palace.[2] After Jingzhao experienced a civil war and was conquered by the general Ma Chao, Yan "restored good and popular government" upon becoming the region's grand administrator.[2][3] People at the time largely had little experience in farming.[4] Yan encouraged his people to do urban agriculture work, suggesting that they use their leisurely time to farm.[3] At his home, Yan started vegetable plots.[3] Observing that the citizenry were in the predicament of lacking carts and cattle, he urged them to make carts, sell pigs and dogs, and buy cattle.[4] Within two years, nearly all households had carts and cattle.[5] According to the Chinese historical text Weilüe, under Yan's leadership, Jingzhao became the best of Yongzhou's ten prefectures.[6]
