《新唐书·列传·卷六十五》
此前，裴冕在河西，奉诏归京，路上在平凉遇到了太子，于是跟随他到了灵武。裴冕和杜鸿渐、崔漪一起劝太子登基说： 皇帝对辛劳厌倦了，并已南去蜀地，国家皇位，应有归属；现天意人心，都朝向您，应登基称帝；如有犹豫，使万民失望，国家就完了。 
初，冕在河西，方召还，而道遇太子平凉，遂从至灵武，与杜鸿渐、崔漪同辞进曰： 主上厌于勤，且南狩蜀，宗社神器，要须有归。今天意人事，属在殿下，宜正位号。有如逡巡，失亿兆心，则大事去矣。 
Before that, Pei Mi was in Hexi, returned to Beijing on the imperial edict, and met the prince in Pingliang on the way, so he followed him to Lingwu. Pei Mi, Du Hongjian, and Cui Yi persuaded the prince to ascend the throne, saying: "The emperor is tired of hard work and has gone south to Shu. The imperial power of the country should belong to him; now the will of heaven and the hearts of the people are all towards you. You should ascend the throne and become the emperor; if you hesitate, and disappoint the people, the country will be over."
