The transformation of Kun and Peng refers to the story of a fish named "Kun" turning into "Peng" in ancient Chinese mythology.
In "Xiaoyaoyou", Zhuangzi recorded the ancient and magical legend of this Chinese nation with the first sentence: "There is a fish in the North Ming Dynasty, and its name is Kun. Kun is so big that I don't know how big it is." Thousands of miles away, it turns into a bird, and its name is Peng; the Peng's back does not know its thousands of miles; it flies in anger, and its wings are like clouds hanging from the sky. It is a bird, and it will migrate to Nanming. The one in Nanming is also the Tianchi." The following article gives many examples to illustrate that "summer insects cannot speak of ice", and it is impossible to understand high-level things on a low-level platform. At the end of the article, "My old husband knows that he can serve as an official, his behavior can be compared with that of his hometown, his virtue can be matched with that of a monarch, and he conquers a country, he thinks of himself like this. But Rongzi of Song Dynasty still laughed at it. And he praised it throughout the world without any persuasion. It is enough to judge the difference between inside and outside, and to judge the situation of honor and disgrace. Although there are no numbers in the world, Fuliezi is still walking in the wind. , Ling Ran is good, and then he will turn around after five days. Although this is not necessary, there is still something to be expected. How can he be treated badly by those who have traveled endlessly? Therefore, it is said: The perfect person has no self, the god has no merit, and the saint has no name.
Translation: Therefore, those talents are enough to be qualified for an official position, and their conduct is consistent with their hometown. People hope that their morality can satisfy the king and their ability can win the trust of the people of the country. They treat themselves like this, but people in the world laugh at them, and he will not work harder because of it. People criticize him, but he will not be more depressed because of it. He clearly distinguishes the difference between himself and the outside world, and distinguishes the boundaries between honor and shame. That's it! Song Rongzi never rushes towards the whole society. Even so, he could not reach the highest state. He could walk on the wind, which was so light and beautiful, and he never seemed to be in a hurry to pursue happiness. Although this eliminates the labor of walking, it still has something to rely on. As for following the laws of the universe, grasping the changes of the "six qi", and traveling in endless realms, what else can he rely on? Therefore, it is said that moral cultivation is noble! The "perfect man" can reach the state of selflessness, the "god man" whose spiritual world is completely transcendent has no fame and career in his mind, and the "sage" who has perfected his ideological cultivation never pursues fame and status.
The center is placed on the last sentence, which shows that he is a person who is indifferent to fame and wealth, is not disturbed by the outside world, and pursues inner indifference to achieve independent communication with the spirit of heaven and earth, and then truly travel freely
