In the past, Zhuang Zhoumeng was a butterfly, which was lifelike, and it was a metaphor for his own ambition, but he didn't know Zhou Ye. If you feel it suddenly, you will feel it suddenly. I wonder if the dream of Zhou is a butterfly and the dream of butterfly is a week and? Zhou and butterfly, there must be points. This is called materialization. ("Zhuangzi's Theory of Everything")

Zhuang Zhoumeng Die, who wrote "Zhuangzi's Theory of Everything", is a new philosophical proposition put forward by Zhuang Zi, the main representative of Taoist school in the Warring States Period. Among them, Zhuangzi used romantic imagination and wonderful writing style to describe and discuss the events that changed into butterflies in dreams and butterflies turned into their own after waking up, and put forward the view that it is impossible for people to accurately distinguish between truth and illusion and materialization of life and death. Although the story is extremely short, it became the representative of Zhuangzi's poetic philosophy because it permeated the essence of Zhuangzi's poetic philosophy. Also, because it contains romantic thoughts and feelings and rich philosophical thinking about life, it has caused many literati and poets in later generations to sing * * *, which has become a topic they often chant, and the most famous one is "the sage Chuangzi is day-dreaming, bewitched by butterflies, the spring-heart of Emperor Wang is crying in a cuckoo" as Li Shangyin said.
