Kunpeng's spread of wings originated from Zhuangzi's Free Travel in the Warring States Period.

Original text:

"There are fish in the north, called Kun. Kun is so big, I don't know its thousands of miles; Become a bird. Its name is Peng. Peng's back is thousands of miles away; Fly away angrily, its wings hang in the sky like clouds. If it is a bird, shipping will migrate to Nanming. (Excerpted from "Zhuangzi Xiaoyao Tour")

Translation:

In the far north, there is a sea. There is a kind of fish in the sea. Its name is Kun. This Kun is very big, thousands of miles away. Later it became a bird, and its name was Peng. This Peng is very big, only its back, not to mention thousands of miles.

It flapped its wings and flew away, and its wings covered the sky like dark clouds. This bird flying at sea is going to the South China Sea. (Excerpted from "Zhuangzi Xiaoyao Tour")

Extended data story creation background:

Zhuangzi was brilliant, intelligent and diligent, and "learned everything". He is not born useless. However, "today, the world is also confused. Although I have a prayer, I can't get it. " On the one hand, the corrupt society that "those who steal hooks will be punished and those who steal countries will be punished" makes him disdain to associate with them; On the other hand, the reality of "princes can't do it" makes him unable to show his ambition.

Since the world is so filthy and he can't talk to Zhuang, his soul seeking freedom has to soar in the fantasy world and seek liberation in the realm of absolute freedom. It is in this situation that he wrote the song "Happy Travel", which is the pursuit of suppressing the soul.

Happy Travel is the first article in Zhuangzi, which represents Zhuangzi's philosophical thought. "Wandering freely" is Zhuangzi's ideal of life and the core content of Zhuangzi's life theory. "Endless travel" means "endless travel without waiting", which is independent of worldly things, integrated with naturalization and free to travel in the world without any constraints.
