《北史·列传·卷三》
丕任官历经六世，将近七十年时间，地位高至公卿辅政大臣，最后又被降为庶人，可是他心中仍想念朝廷，不能忘却人事世情。
丕仕历六世，垂七十年，位极公辅，而还为庶人，然犹心恋京邑，不能自绝人事。
Pi served in various official positions for six generations, for nearly seventy years, holding such a high position as a senior official and auxiliary official, but in the end was demoted to a commoner. However, in his heart he still missed the imperial court and remembered affairs and human relationships.
