Emperor Mingzong had long been respectful of Feng's capabilities and virtues. As Emperor Mingzong was himself illiterate, and his chief advisor An Chonghui, while literate, was not well-learned, An recommended setting up a system where chief scholars would advise the emperor on historical and literary matters. Emperor Mingzong thereafter established two posts for imperial scholars at Duanming Hall (), and commissioned Feng and Zhao Feng to those posts. In 927, Emperor Mingzong further made both Feng and Cui Xie chancellors, with the designation of "Tong Zhongshu Menxia Pingzhangshi" (), along with the title of "Zhongshu Shilang" (中書侍郎, deputy head of the legislative bureau). (Feng's commission was somewhat of a compromise choice by Emperor Mingzong, as the senior chancellor Ren Huan recommended Li Qi, while Kong, then one of Emperor Mingzong's chiefs of staff ("Shumishi") (along with An), pushed for Cui.) While serving as chancellor, Feng often pointed out to Emperor Mingzong the difficulties that farmers faced, and Emperor Mingzong collected the poems that Feng wrote about such difficulties, often having attendants read the poems to him. Emperor Mingzong created him the Duke of Shiping.
