He was the first prophet in the world to classify the wind, and Emperor Taizong obeyed him.

Shu Shu, like Bai Juyi's pipa girl, has always kept the mystery of hiding half her face in front of us behind the guitar.

Li and Yuan Tiangang were the most famous and mysterious astrologers in the period of Emperor Taizong.

According to many mathematical researchers, Li's divination was far from simple mathematical skills, so that people who knew mathematical skills at that time doubted whether he was in a coma.

Li himself is a legend. His father, Li Bo, was an official in the Sui Dynasty. Li Bo was frustrated in officialdom and devoted himself to Taoist studies after he resigned. Since childhood, Li has been intelligent and studious, reading widely, especially proficient in astronomy, calendar, mathematics and art, which is not unrelated to his father's addiction to Taoism. Li was brilliant since childhood, and he read extensively with his father, especially good at astronomical calendar calculation. It is also the first scientist in the world to classify the wind.

In the 14th year of the Great Cause of Sui Dynasty (6 18), Li Yuan proclaimed himself emperor and named Li Shimin king of Qin. In the second year of Tang Gaozu Wude (6 19), Li returned to his hometown at the age of 17, calculated the emperor, and asked his good friend Liu Wenjing to recommend him to join the army as Qin's secretary. As an official after China's entry into WTO, Li proposed a new law, which won the appreciation of Emperor Taizong and He. After that, he wrote a book about astronomical mathematics, discussing the order of officials to officials.

According to historical records, Li was never shy when he met Emperor Taizong. Obviously, his achievements made Tang Taizong sit up and take notice of him.

Ji Fang, Biography of New Tang Book 217: "Emperor Taizong got a secret prophecy that" there was a female king of Wu in the middle of the Tang Dynasty ". When he asked Feng Chun, he said to him, "The sign has come true. It is already in the palace. After another 40 years, the king, the king and the descendants of the Tang Dynasty were exhausted. The emperor said, "I beg and kill, but what can I do?" To Japan: "God has decided that we can't go, but Ken Wang's death will only make the suspect obscene and innocent. "There will be your dear, forty years old, always benevolent, although eventually changed his surname, but absolutely can't be tang. Killing is strong, killing is more, and children and grandchildren are completely harmonious! " The emperor took his words and stopped. "

It means that Emperor Taizong got a secret prophecy, which said: "The Middle Road in the Tang Dynasty was weak, and a Wu woman replaced Tang as king." Li took it to ask, and Li replied, "This brand has been formed, and it is in the palace. After forty years as king, the slaughter of the descendants of the Tang Dynasty will come to an end. " Taizong said, "How about I find out and kill her?" Li said: "This is God's will, and people can't disobey it. If the person looking for the future king can't die, he will kill innocent people for nothing. And the people your majesty loves will be old in 40 years, and they will have a kind heart when they are old. Although they inherited the throne and changed their surnames, they could not destroy Tangmen. Now even if we find this man and kill him, God may give birth to stronger people to vent their resentment, so there will be no survivors in your majesty's descendants! " Emperor Taizong adopted his suggestion and didn't pursue it.

From this perspective, Wu Zetian was able to avoid the disaster of Emperor Taizong, relying entirely on Li's persuasion of Emperor Taizong. From another aspect, we can also see that Emperor Taizong trusted Li.

One day, in the dialogue between the monarch and his subjects, Emperor Taizong asked Li to calculate the national fortune. When he was afraid, Li gave him the excuse that the secret should not be revealed. Instead of insisting, Emperor Taizong led him to a tall building, ordered people to remove the escalator, and then said to Li, "There is no place between heaven and earth here. What you said is only you, and I know you can rest assured. "

Regarding the relationship between Yuan Tiangang and Li, some people say that they are apprentices, while others say that they are rivals.

The fame of the two men has always been equal. Although they are both metaphysicians, they are not contending. According to legend, what Li deduced from later generations at that time rose for more than 2,000 years, and Yuan Tiangang thought that Li had violated the secret, so he pushed him on his back to stop him. This is the origin of the famous push.

The accurate prediction made Li a master of Yi-ology and Shu-Shu, but what really impressed future generations was their extremely mysterious prophecy book "Pushing Endorsement".

There are 60 articles in TuiBei Diagram, each of which consists of a picture, a scale and a recitation. Illustrated with pictures and texts. Through the combination of Yi-ology, poetry and riddles, the mystery is extremely hidden in a "four-in-one" way.

After each era has passed, people will look back and find that the prediction of this book is surprisingly accurate. It can be regarded as the most complete prophecy book so far. TuiBei Map predicted the rise and fall of China for thousands of years after the reign of Emperor Taizong in the order of historical development, which attracted worldwide attention.
