《资治通鉴·唐纪·唐纪四十》
当初，元载任新平尉时，裴冕曾向朝廷推荐过他，所以，元载推举裴冕出任宰相，也因为裴冕年老多病，便于控制。
初，元载为新平尉，冕尝荐之，故载举以为相，亦利其老病易制。
At the beginning, when Yuan Zai was serving as the Xinping Lieutenant, Pei Mian recommended him to the court. Therefore, Yuan Zai recommended Pei Mian for the position of prime minister because Pei Mian was old and suffered from many illnesses, making him easy to control.
