《淮南子·主术训》
这也就像螣蛇在雾中升腾、应龙驾云上升、猿猴在林中敏捷跳跃，鱼得到水，则游得飞快，都是由这些生物体的生理特性所决定。
夫螣蛇游雾而动，应龙乘云而举，猨得木而捷，鱼得水而鹜。
It is just like Teng She (a gigantic snake) flying up in the fog, Ying Long (a winged dragon) flying up on the clouds, and monkeys leaping swiftly in the forests, fish swimming fast in water, as these are determined by their physical characteristics.
