Zhuangzi said: "Gui can be eaten, so cut it down; lacquer can be used, so cut it. Everyone knows its useful uses, but no one knows its useless uses."

This The general idea of ??the sentence: The trees on the mountain all caused their own felling because the materials were usable. The oil and candles lit themselves because they could be burned for lighting. The cinnamon bark was fragrant and edible, so it was cut down, and the resin was cut down because it could be used for baking. People are aware of the uses of useful things, but they don’t understand the greater uses of useless things.

That is to say, people usually see useful things, but in the end, these so-called useful things They all end up being slaughtered and used, while the truly "useless" things are happy and contented.

From this point of view, Zhuangzi's sentence contains deep dialectical thinking. This sentence comes from "The Human World" profoundly reflects Zhuangzi's thought of inaction.
