Li Shimin asked Yuan Tiangang about the fate of the Tang Dynasty. Why did Yuan Tiangang tell Li Shimin "When will pigs climb trees"?

There have been 24 dynasties in the history of China, but when it comes to emperors, there are really not many emperors who have been passed down to later generations, and Li Shimin in the Tang Dynasty is one of them. At the end of Sui Dynasty, the princes stood side by side, and Tang Yuan and his son rose up, while Li Shimin was more farsighted. After he hit the land of the Tang Dynasty, he experienced the change of Xuanwu Gate, killed the prince and became the emperor, and began to expand his territory and sweep around. First of all,

In addition to creating a prosperous time, Li Shimin also selected imperial examinations, reused common people and suppressed powerful people. During his time, many nobles were suppressed one after another, and civilians in cloth were promoted, which led countries to pay tribute to Korea and neighboring countries, including Japan, North Korea, Vietnam and other countries. It was this great feat that led Li Shimin to be called Tiankhan by other countries, but in his later years, Li Shimin became more and more fatuous, not only exulting, but also less enlightened than before.

However, Li Shimin has been worried that his country will be unstable. He also knows that no dynasty can exist forever, and the lessons of the former Sui Dynasty are just around the corner. If he doesn't take precautions, it will definitely pose a threat to the social security of the Tang Dynasty in the future. At that time, there were many masters who were proficient in Feng Shui in the Tang Dynasty. Two of them are very good, one is Li and the other is Yuan Tiangang. They once collaborated on a book called Push Endorsement, which predicted the history of China in 2000.

This book is China's first wonderful book, and its predictions for later generations are very accurate, even reaching an alarming level, including a series of important events such as Wu Zetian's accession to the throne, Song Taizu Zhao Kuangyin, Genghis Khan, the Qing Dynasty's entry into GATT and Eight-Nation Alliance's invasion of China. At that time, Li Shimin called a Yuantian plough to calculate the national luck of Datang, but Yuantian plough knew that the secret could not be revealed and was unwilling to tell Li Shimin what the national luck of Datang was like.

But as an emperor, anyone who wants to know the answer can't go against it, even if it is better than Yuan Yuan plough. Finally, Yuan Tiangang had no choice but to let the cat out of the bag and tell Li Shimin that once the pig climbed the tree, Li Tang's country would perish. At that time, Li Shimin was very happy to hear the news, thinking that the mountains and rivers of Datang could not be done, because pigs could not climb trees, but he never thought that Zhu Wen and Li Shimin, the back beams of the Five Dynasties and Ten Kingdoms, did not think of it. It seems that even emperors through the ages can't compete with God's will.
