《汉书·志·五行志下之上》
又一说，天地间的特性人是宝贵的，凡是人为的变化，都属于皇极下人伐上的怪异。
一曰，天地之性人为贵，凡人为变，皆属皇极下人伐上之疴云。
Another theory is that humans’ characteristic belongs to the heaven and the earth, and all the transformation by humans belongs to the abnormal phenomenon of the people oppressing their superiors under the Imperial Pole.
