Tao Yuanming "refused to bow his head for five pecks of rice" and retired to the countryside, so the world is not a scheming Tao County Magistrate, but a hermit who "built a hut in the human world without the noise of cars and horses", a Mr. Wu Liu who created a spirit for all hermits for thousands of years. It was Li Bai who was full of pride, but his career was not smooth, so he resigned angrily and rode his white deer to wander around the famous mountains and rivers of the motherland. From then on, the world was not a clerk who curryed favor with the powerful, but a poet Li Bai who was famous for thousands of years. It was Sima Qian who lived in disgrace and suffered castration, but was determined to write "Historical Records", so people's desks had a "historian's masterpiece" instead of a lonely ghost exposed in the wilderness... They are all examples of failure in advancement and success in retreat.
