Named after the artist Wu Che-Yu, the soul fish was born in the void and crystallized from human emotions.

Fluttering silently and slowly, their bodies almost disappeared in the light of the deep sea.
The fish swims freely, and this is the happiness of the fish.
If we are not a fish, how do we know the joy of a fish?
How do we know that we do not know the joy of fish?
We will only learn about it when we come to the riverside.

Inspired by Zhuāngzǐ: "The Debate on the Joy of Fish" c. 3rd century BC
