《庄子·外篇·秋水》
跳入水中井水漫入腋下并且托起我的下巴，踏入泥里泥水就盖住了我的脚背，回过头来看看水中的那些赤虫、小蟹和蝌蚪，没有谁能像我这样的快乐!
赴水则接腋持颐，蹶泥则没足灭跗。还虷蟹与科斗，莫吾能若也。
"When I jump into the water, the water in the well reaches my armpits and supports my chin, I step into the mud and the mud covers my toes, I turn my head and look at the red worms, small crabs, and tadpoles in the water, not one of them is as happy as I am!"
