《论衡·卷十八·齐世篇》
一般还讲到古代根据人的生理特点合理地使用老百姓，驼背的让他去守门，是侏儒就让他当俳优，如果都高大貌美，怎么会有驼背、侏儒这样的人呢？
语称上世使民以宜，伛者抱关，侏儒俳优。如皆侗长佼好，安得伛、侏之人乎？
Generally speaking, it is also mentioned that in ancient times, people with different physiological characteristics were used reasonably. The hunchbacked ones were sent to guard the gate, and the dwarves were sent to be clowns. If everyone was tall and beautiful, how could there be hunchbacked and dwarfish people?
