《魏书·列传·卷九十二》
当初，齐献武王坚决推辞天柱大将军的职位，皇帝令魏收起草诏书，答应他的请求，并且想要升任其为相国，就问魏收相国属于哪个等级，魏收照实回答，皇帝才没有这样做。
初，齐献武王固让天柱大将军，帝敕收为诏，令遂所请，欲加相国，问收相国品秩，收以实对，帝遂止。
In the beginning, King Xianwu of Qi steadfastly declined the position of Great General of Tianzhu, the emperor ordered Wei Shou to draft an edict agreeing to his request, and wanted to promote him to Minister of State, so he asked Wei Shou what rank a Minister of State was, Wei Shou answered truthfully, so the emperor did not do so.
