《论衡·卷一·逢遇篇》
只能驾御日跑百里马的人，而要他去驾御千里马，必定有毁坏衡木折断轭木的危险；只有使用备位充数臣子的才能，却用他去驾御有大臣才智的人，就必然会有才智受压抑的不正常现象。
御百里之手，而以调千里之足，必摧衡折轭之患；有接具臣之才，而以御大臣之知，必有闭心塞意之变。
It is only possible to drive a horse that runs a hundred miles a day, and if you want him to drive a千里马, there is bound to be the danger of breaking the horizontal wood and breaking the yoke; Only use the talents of the substitutes to make up the number of ministers, but use him to control the talents of the ministers, there will inevitably be an abnormal phenomenon of talents being suppressed.
