Li Shimin asked Yuan Tiangang when the Tang Dynasty would perish. What did Yuan Tiangang answer?

At this time, Yuan Tiangang answered Li Shimin and said, When will the pigs get on the tree? At that time, Li Shimin was very happy to think that his legacy could last for hundreds of years. In people's traditional thinking, they are all relatively heavy animals, and it is impossible to climb trees. To Li Shimin's surprise, Yuan Tiangang's pig is actually homophonic. In the end, Datang was really ruined by Zhu Wen. Yuan Tiangang, a native of Sui and Tang Dynasties, was very famous at the end of Sui Dynasty. At that time, people said that he could call the wind and rain, and the good or bad of a person or even a family could be judged from the whistling sound and specific blowing direction of the wind. It can be said that he is a very famous metaphysician. After people's verification, he found that his inferences were very accurate, so many people admired him. At that time, Li Shimin also knew about Yuan Tiangang, so one day he was invited to the attic to count his luck for the whole Tang Dynasty. At that time, Li Shimin asked him directly when his country would perish. Yuan Tiangang said these four words only when the pig climbed the tree after his own inference. At that time, Li Shimin was very happy after hearing this. He thinks that You Zhu is fat and stupid, so it is impossible to climb trees. Yuan Tiangang means indirectly telling him that the inheritance of the Tang Dynasty will last forever. But what people didn't expect was that what Yuan Tiangang inferred at that time was not wrong, but what he said about pigs was just a homonym. At that time, the whole Tang Dynasty was really dragged down by Zhu Wen. Zhu Wen is a very capable person. At first, he started as a humble soldier and eventually became the King of Liang through his own struggle. At that time, he cultivated his power in Henan. When I had enough ability, I began to lead my own army to attack the capital directly, so as to force Tang Chaozong to abdicate. If it weren't for Zhu Wen, the Tang Dynasty wouldn't have perished so quickly. Thus, Yuan Tiangang's inference at that time was also very accurate. Unfortunately, the pig he said is not a real pig, but a person named Zhu. Unfortunately, Li Shimin didn't guess at that time.
