Although Yuan Tiangang has no official rank and no real duties, he can always accompany him around Emperor Taizong. Li Shimin often invites Yuan Tiangang to visit the people around him and regards it as a pleasure. Yuan Tiangang in this period was not so much a physiognomist as a cross talk, just playing with Emperor Taizong.
Having such a divine operator around Emperor Taizong will definitely let him do his own thing. Most people are most concerned about their own future and life span, and Emperor Taizong is no exception. He often consulted Yuan Tiangang about his own situation. But it is extremely dangerous for Yuan Tiangang, and it will kill you. After all, disaster comes from the mouth and companions are like tigers. Therefore, it is really difficult to answer the question of Emperor Taizong.
Emperor Taizong is already an emperor, so there is no need to look at his future prosperity. After all, he was an emperor and there is no possibility of promotion. But Emperor Taizong was very concerned about his life, although he didn't look for elixir everywhere like Qin Shihuang and Han Wudi. Whenever Emperor Taizong asked about his deadline, Yuan Tiangang replied: Long live, long live, long live to prevaricate. Emperor Taizong knew that he could not live forever, but he did not embarrass Yuan Tiangang.
Compared with his own life span, Emperor Taizong was more concerned about the national wealth of the Tang Dynasty. When can the national wealth last? At first, when Emperor Taizong asked this question, Yuan Tiangang avoided talking about it, or said that his ability was limited and he could not speculate. But every time he got such an answer, Emperor Taizong was very unhappy.
Later, Yuan Tiangang felt that he was not free around Emperor Taizong. There is no sky outside, so he can wander around freely. And there will be danger at any time, so I want to find a reason to retire and leave the court. When he asked Emperor Taizong to abdicate and return to his hometown, Emperor Taizong disagreed. Later, he offered to resign many times. When Emperor Taizong saw that he couldn't stay any longer, he agreed, but on one condition, he answered a question. This question is a cliche. It is said that if the answer is accurate, Yuan Tiangang will be released. In fact, this is also the reason why Emperor Taizong wanted to embarrass Yuan Tiangang. The question is: When will the Tang Dynasty last?
Yuan Tiangang replied: "When will pigs climb trees!" Emperor Taizong was stunned at first, and then he was very happy. Pigs can't climb trees, that is, the Tang Dynasty can last forever. So I asked Yuan Tiangang to go home.
In fact, Yuan Tiangang means that the Tang Dynasty called Li a tree, and "pig" was homophonic with "Zhu". In 907, Zhu Wen replaced the Tang Dynasty and built a girder. Zhu Wengang revolted with Huang Chao. Later, he took refuge in the Tang Dynasty and became a powerful minister like Cao Cao, playing with the emperor of the Tang Dynasty. Later, the emperor of the Tang Dynasty ceded the throne to him.
