《贞观政要·卷五·论公平》
德彝坚持他原来的想法，太宗即将跟从他的建议，胄又驳斥道： 校尉因为无忌的缘故以招致罪害，按照法律当从轻处理，如果讨论他的过失和错误，则是为了感情的缘故，然而生死差距巨大，我才敢于顽固地请求。 
德彝执议如初，太宗将从其议，胄又驳奏曰： 校尉缘无忌以致罪，于法当轻，若论其过误，则为情一也，而生死顿殊，敢以固请。 
Deyi insisted on his original idea, and Taizong was about to follow his advice. Zhou refuted again: The school captain was convicted because of Wuyi, and should be treated leniently according to the law. If his faults and mistakes are discussed, it is for the sake of emotion. However, The gap between life and death is huge, so I dare to stubbornly ask.
