《庄子·外篇·天道》
那么，天地原本就有自己的运动规律，日月原本就存在光亮，星辰原本就有各自的序列，禽兽原本就有各自的群体，树木原本就直立于地面。
则天地固有常矣，日月固有明矣，星辰固有列矣，禽兽固有群矣，树木固有立矣。
So, heaven and earth originally have their own laws of motion, the sun and moon originally have their own light, the stars originally have their own sequences, birds and beasts originally have their own groups, and trees originally stand upright on the ground.
