it's better to forget about each other than to be in the Jianghu. From Zhuangzi's Inner Chapter, The Great Master.

It means that the spring water is dry, and the fish's saliva moistens each other. Why not go to the big rivers and lakes separately for more freedom? Metaphor is to help each other with meager strength in difficult situations; Sometimes you might as well give up clinging and welcome the world with a new self.

here, Zhuangzi brilliantly expressed the view that "Tao" can change things.

the understanding of this sentence can be related to "a poor family makes a dutiful son" and "a loyal minister in troubled times". While praising dutiful sons and loyal ministers, we ignore "family poverty" and "troubled times". Similarly, the reason why two fish need to "care for each other" is because the spring water has dried up.

The meaning of "forgetting each other in rivers and lakes" does not mean that people who once knew each other were cut off because of feelings or other factors. It refers to two strangers who do not contain emotional colors such as love or hate. The word "forget" in this sentence is a common way used by ancient people in China to express the contradiction between Yin and Yang.

Future generations' inspiration:

We care for each other because of need, some because of material needs, and some because of spiritual needs. Affection, as if no one can live without anyone, although so "tight", but as long as you adapt, you can feel happy;

Forget about Jianghu. For the sake of freedom, one's freedom is not easy. Two people's freedom is hard-won, and more people's freedom is even more difficult. Everyone's freedom is just a utopia. How to choose is a choice that everyone must face in his life.
