《资治通鉴·汉纪·汉纪二十一》
京房说： 齐桓公、秦二世也曾经知道周幽王、周厉王的故事，并讥笑过他们。可是，齐桓公任用竖刁，秦二世任用赵高，以致政治日益混乱，盗贼满山遍野。为什么不能用周幽王、周厉王的例子测验自己的行为，而觉悟到用人的不当？ 
房曰： 齐桓公、秦二世亦尝闻此君而非笑之；然则任竖刁、赵高，政治日乱，盗贼满山，何不以幽、厉卜之而觉寤乎？ 
Jing Fang said: Duke Huan of Qi and Qin Er Shi also knew the story of King You of Zhou and King Li of Zhou, and even sneered at them. However, Duke Huan of Qi appointed Shu Diao, and Qin Er Shi appointed Zhao Gao, resulting in increasing political chaos and robbers running rampant everywhere. Why couldn’t they use the cases of King You of Zhou and King Li of Zhou to examine their own behavior and realize their improprieties in appointing people?
