新五代史
In 950, Feng wrote an autobiographical note titled the "Self-Description of the Old Man from Changle" () that discussed family history and his career, including the honors that had been bestowed on him and his family members by the succeeding dynasties. (This text drew severe criticism from the later Song Dynasty historians Ouyang Xiu (the lead editor of the "New History of the Five Dynasties") and Sima Guang (the lead editor of the "Zizhi Tongjian"), both of whom described Feng as disloyal and the most wicked among officials as a result.)
