《新唐书·列传·卷三十》
许敬宗说： 汉文帝的舅父薄昭，保护文帝从代地回朝登上帝位有功，后来犯了杀人罪，文帝怜惜他又怕扰乱了法律，就命令朝臣们穿上丧服上门去为他哭丧，薄昭便自杀了，优秀的史官不认为这不妥当。
敬宗曰： 汉文帝舅薄昭，从代来有功，后坐杀人，帝惜挠法，令朝臣丧服就哭之，昭自杀，良史不以为失。
Xu Jingzong said: Bo Zhao, the uncle of Emperor Wen of the Han Dynasty, had the merit of protecting Emperor Wen from returning to the court from Yan and ascended to the throne. Later, he committed the crime of murder. Emperor Wen felt sorry for him and was afraid of disturbing the law, so he ordered the ministers to wear mourning clothes and go to his door to cry for him. Bo Zhao then committed suicide. Excellent historians did not think it was a problem.
