《魏书·列传·卷八十一》
其亲信在宫廷内任职者一律逐出宫门之外。我由于观察处置不明，抚养了这样的豺虎，回顾过去的谬误，实有愧于臣民，但可以时时告诫自己，以谢朝野。 
所亲在内者悉令出禁，朕昧于处物，育兹豺虎，顾寻往谬，有愧臣民，便可时敕申没，以谢朝野。 
All his confidants who hold positions in the palace shall be expelled from the palace gate. Because of my unclear observation and handling, I have raised such a jackal. Looking back on the past mistakes, I am really ashamed of my subjects, but I can always remind myself to thank the court and the country.
