《淮南子·人间训》
现在如果拿五帝、三王的道德仁义用到五霸这时代，这就好像骑着千里马在莽莽丛林中追逐，只会像斗笠打转盘旋。
今取帝王之道，而施之五霸之世，是由乘骥逐人于榛薄，而蓑笠盘旋也。
Now, if the morality and benevolence of the Five Emperors and the Three Kings are used in the era of the Five Tyrants, it is like riding a thousand-mile horse in the dense jungle, and it will only go round and round like a hat brim.
