《北史·列传·卷二十三》
王劭上奏说： 微臣所知，黄帝杀炎帝，本系同母弟，周公诛管叔，原也亲手足。叔向戮叔鱼，孔子赞其有古人刚直之风；石衜杀石厚，左丘明认为是大义灭亲。
劭上书曰： 臣闻黄帝灭炎，盖云母弟；周公诛管，信亦天伦；叔向戮叔鱼，仲尼谓之遗直；石蜡杀石厚，丘明以为大义。
Wang Shao petitioned: I know that the Yellow Emperor killed Yandi, who was his younger brother, and the Duke of Zhou killed Guan Shu, who was also a brother. Shu Xiang killed Shu Yu, and Confucius praised him for having the upright style of the ancients; Shi Li killed Shi Hou, and Zuo Qiu Ming believed it was a great duty to kill his own relatives.
