Do some people think that "Yu Gong Yi Shan" is actually an ironic story?

I don't think so. Because this is Tang Wen's example, and what is an example, immortality. Why do I say that? This is well-founded. Please see:

There is a wizard named Ji Xian in the state of Zheng. He can predict good and bad luck. He can calculate that someone will die on a certain day in a certain year, and he never makes mistakes. Liezi was very respectful and said to his teacher, nothing, "I thought the way of being a gentleman was the most remarkable, but I didn't expect anything more remarkable than you." The pot said, "Tell him to come and see my fortune."

When Wu Xianchu came, the pot showed the earth. After seeing the photos, Wu Xian said to Liezi, "I saw the wet ashes, and your teacher will die in ten days." Liezi went in and told the pot with tears. The pot said, "Tell him to come again." The next day, the pot showed signs of heaven. Wu Xian came out and said to Liezi, "Your teacher is so lucky. Fortunately, he met me and turned around. I brought him back to life. " Liezi happily went in and told the pot. The pot said, "Tell him to come again." On the third day, a holographic face appeared in the pot. Wu Xian-jing, seeing everything in the world, dared not talk nonsense. He came out and said to Liezi, "Your teacher is dishonest and deliberately hides his inner desires in his face. What can I think? " Liezi went in and told the teacher. The pot said, "Tell him to come again." On the fourth day, the pot showed no phase. When Wu Xian saw it, he couldn't stand, and turned and ran. Liezi couldn't catch up with him and came back to ask what happened to the pot.

"Pot" tells the story: "People always speculate on everything with their very limited knowledge. Wu Xian only knows a lot, especially ordinary people. Ordinary people think they are enlightened by heaven, authentic and humane, and oppose the way of nature with enlightened heart, so wizards can visit fortune-teller and even predict accurately. In fact, it is not the fortune teller who knows the truth, but the fortune teller unconsciously tells the fortune teller. This Wu Xian can see the face of our land and my heaven-this is the face of two kinds of people-this is a little skill to make a living. On the third day, I showed him the holographic face, but he couldn't understand it. On the fourth day, I showed him the pure nature, and he knew that the position of seeing and being seen was completely reversed. So I didn't dare to be arrogant again and ran away quickly.

Liezi knew that he had learned nothing from the teacher's wisdom, so he went home and cooked for his wife honestly for three years. Treat any creature at ordinary times with respect like a human being, and don't pretend to know everything all your life. In this way, Liezi is naturally like dirt and finally becomes a fairy.

You try to think about it, what the immortal wrote must be more real, more inspiring and make you understand. Since I am a fairy, I certainly know that there are mountain gods, and I also know that the world is endless and life is endless. It's just that people now, of course, don't believe this. No way, with the development of science, people are getting farther and farther away from God. Ancient people could practice against the wind, but now they can't. People are too impetuous.
