Keiko is a famous argumentative person. She is more of an exploratory cognitive attitude towards things, lacking aesthetics and care.
Zhuangzi thinks that the "happiness" of fish is actually the projection and externalization of his happy mood, which is the concrete proof that he sincerely feels happy in a free and lively life. Zhuangzi pursues "Heaven and earth coexist with me, and all things are one with me", living in harmony with all things and the outside world. He thinks that the "happiness" of fish is actually the projection and externalization of his happy mood. Zhuangzi also advocated "nature" and opposed "man-made". Fish swim freely in the water, which is in line with Zhuangzi's ideal. Therefore, he came to the conclusion that it is natural for fish to be "happy".
It's good to agree with either of them. If you have to choose between two, you can choose to praise Zhuangzi. Being detached from things and returning to the things themselves to enjoy their beauty is a romantic and happy life.
Personally, I appreciate Zhuangzi, because Zhuangzi can enjoy life more and appreciate beauty more.
