《北史·列传·卷二十八》
 自从去年大驾南征以来，李彪兼任尚书，我与他朝夕共事，才知道他言行暴戾，自以为是，好责人非，独断专行，横行无忌，惟我独尊，轻视别人。
及去年大驾南行以来，彪兼尚书，日夕共事，始乃知其言与行舛，是己非人，专恣无忌，尊身忽物。
Since His Majesty went on his expedition to the south last year, Li Biao has been acting as the Shangshu (minister of staff), and I've worked with him every day and night, and I've only just learned that his words and actions are violent, that he's self-righteous, that he likes to blame others for his mistakes, that he makes hasty and arbitrary decisions, that he runs roughshod over others, that he thinks he's the only one who matters, and that he looks down on others.
