Creative background:

The mid-Warring States period in which Zhuangzi lived was a period of dramatic social transformation in history. China society has undergone a great change, and people in troubled times are full of confusion about life and the future.

In view of the fact that people can't let their nature live freely in the cruel reality, and it's hard to enjoy life in the face of ruthless destruction, Zhuangzi carefully hides in the front, adapts in time, does not seek far harm, looks for cracked space, and avoids being destroyed or enslaved, thus preserving nature and cultivating spiritual life. This article was written in this state of mind.
