《魏书·列传·卷十九》
至于奉迎皇上，侍卫宫中，这是臣子固有的操节，有关主管官员寻常的行动，不允许拿这些作为功劳，随便设置封邑。
至于奉迎乘舆，侍卫省闼，斯乃臣子之常节，职司之恆理，不容以此为功，妄开井邑。
As for welcoming the emperor and guarding the palace, this is the inherent moral code of a courtier, and it is not allowed to use these as merits and to set up fiefdoms at will regarding the ordinary actions of the officials in charge.
