There is a beautiful legend about Laozi's "purple gas coming from the east": Laozi is knowledgeable and served as an official in charge of books and classics in the Zhou Dynasty. When he was in his seventies, there was chaos in the world, and wars between governors for territory and power often occurred. I expected that there would be more wars in the future, so I resigned and rode on a green cow, leaving Luoyang and heading west to spend my old age. One morning, Guan Lingyin of Hangu, who is good at observing astronomical phenomena, suddenly saw the purple gas in the east and was greeted when he left the customs. Sure enough, he saw an old man with a beard like snow and a fairy wind riding a green cow. This is Lao Zi. Yin left Lao Tzu and asked him to do an article before he left. Laozi wrote an article about "Tao" and "virtue", which was about 5,000 words. Later, people printed this article into a book with the title of Laozi and Tao Te Ching. After writing the article, I rode on a green cow and headed west. I don't know where I went after that. Since then, among many Taoist immortals, Laozi has become the supreme god, known as the "Taiqing Moral Heaven Zun" and respected as the "Tai Shang Lao Jun" among the people.

Although Laozi's Tao Te Ching is only 5,000 words long, it has left many idioms such as "self-knowledge", "good beginning and good ending" and "a journey of a thousand miles begins with a single step", which have been used by the Chinese nation for generations. Now, as soon as you enter Hanguguan Scenic Area, you can feel the cultural atmosphere of "Purple Gas from the East", see the stone statues of Niu Piao, and see the stone carvings of famous sentences such as "Shilin" and "Self-knowledge" written by Laozi. Because Hanguguan exudes a strong historical and cultural atmosphere of "purple gas coming from the east", many overseas tourists come here to appreciate the beautiful style of this historic palace. About Zhuangzi: In Keiko's Xiang Liang, Keiko is a villain who covets fame and wealth and suspects his friends for no reason. Zhuangzi sternly ridiculed him. In "Zhuangzi and Keiko Traveling on Haoliang", Keiko and Zhuangzi play on Haoliang, and debate whether Zhuangzi can know about "Fish Fun", which shows that they are friends who can talk back. Is Keiko really as shameless as in Keiko Xiang Liang? What is the relationship between Zhuangzi and Keiko? Another story can help us solve this problem, that is, the story of "A craftsman makes a fortune" (from Zhuangzi Xu Wugui). It tells the story of Zhuangzi passing by Keiko's grave and lamenting to the students that since Keiko's death, he has no confidant to talk to. Zhuangzi's words are deeply touching, which is rare in the whole Zhuangzi. Visible, in Zhuangzi's mind, Keiko is a rare confidant. So, is the story of "Keiko Xiang Liang" completely fictional? Not all of them. Keiko may be really keen on fame and fortune, but she is unlikely to do anything to hurt her friend Zhuangzi. Zhuangzi and Keiko swim in the original work of Haoliang, and Zhuangzi and Keiko swim in Haoliang. Zhuangzi said: "How leisurely the fish in the river are in the river. This is the happiness of the fish." . "Keiko said," you are not a fish, where do you know that fish is happy? " ? " Zhuangzi said, "You are not me. How do you know that I don't know that fish are happy?" ? "Keiko said," I am not a son, and I really don't know my son. "Zi Gu is not a fish, but he doesn't know the joy of fish." Zhuangzi said, "Please follow its source. Confucius said, "You know a lot about fish." He asked me because he knew what I knew. I am very clear. "
