Li Chunfeng and Yuan Tiangang are two masters who are very important in Chinese folklore, the imperial master of Li Shimin of Tang Taizong. Folklore has a lot to say about them. Li Chunfeng's father, Li Bo, was a county lieutenant of Gaotang County in the Sui Dynasty, and he was well-known in Taoist scholarship, and in the turmoil at the end of the Sui Dynasty, civil servants simply did not make a family and became a Taoist. His son Li Chunfeng was also gifted and intelligent, and it is recorded that he studied the books of a hundred families since childhood, read and memorized strongly, especially the study of mathematics, astronomy, and calendar.
Legend has it that he was good at measuring the trajectory of celestial bodies, and could accurately deduce the changes and trajectories of the sun, moon, and stars. Folk legends even say that through the observation and calculation of the heavens and the earth, the sun, the moon and the stars, he can infer the lack of the sun, moon and stars, and predict the misfortunes of the day and the night. Li Chunfeng also had a deep understanding of Taoist scholarship and inherited his father's scholarship.
After Emperor Taizong of Tang became emperor, Li Shimin opened the Zhenguan Dynasty, and Li Chunfeng was also famous in the folk at this time. After debating the calendar with Fu Renjun, the imperial astronomical official of the Tang Court, he was awarded the rank of General Shilang by the Tang Court and served in the Taishi Bureau. Li Chunfeng was good at making astronomical instruments, and improved and manufactured armillary celestial instruments to greatly improve the accuracy of the Tang Dynasty's observation of astronomy.
Deeply admired by Emperor Taizong of Tang, he was promoted several times to the official positions of Chengwu Lang (equivalent to the Ministry of Works), Dr. Taichang (royal sacrifice and book management), Taishi Cheng and Taishi Ling. According to legend, he wrote the book of Fa Xiang, the Book of Images.
Compared with Li Chunfeng, the direction of Yuan Tiangang's calculation is more to observe people's faces to judge people's fate, while Li Chunfeng tends to observe the astronomical prediction of stargazing and counting the moon to correlate personal fortunes. Yuan Tiangang, like Li Chunfeng, also left a lot of magical legends in the folk, the most famous of which is that he gave Wu Zetian, who was still in his infancy, saying that this young child Dragon Pupil Phoenix Neck was a female doll, but it was the face of the Son of Heaven.
And he gave sui and Tang celebrities a very accurate look, basically within 10 years can be verified, so the people looking for Yuan Tiangang's face are endless, and it is precisely for this reason that Tang Taizong Li Shimin stayed in Chang'an for a long time. Therefore, the later dynasty academic circles regarded Yuan Tiangang and Xunzi in the Spring and Autumn Period as the ancestors of Xiangshu.
So why was Li Shimin, the Emperor Taizong of Tang, so obsessed with metaphysics, and at the same time appointed Li Chunfeng and Yuan Tiangang, two famous metaphysical masters in history, in Chang'an? It can be said that it is unique among emperors. In fact, Tang Taizong also had his own suffering, and it is well known that Li Shimin's position was not orthodox.
Although the Tang Dynasty foundation established his legacy, it has always been the right and left arm of Tang Taizu Li Yuan. It can be said that half of the Tang Dynasty was fought by him, and the light war horses that charged into the battlefield were exhausted and killed eight horses, which is the famous Tanglin Eight Horses. However, Tang Taizu Li Yuan was born into a clan family at the end of the Sui Dynasty, and he was very obedient to feudal theory and believed that the elder and young were orderly.
Therefore, Li Crown Prince was the eldest son Li Jiancheng, and became the successor of the Empire. Therefore, Li Shimin was not willing to let the rivers and mountains that he spilled with his blood be easily taken away by others, so there was the famous "Xuanwumen Change". Killed the crown prince Li Jiancheng and forced Tang Taizu Li Yuan to abdicate.
Tang Taizong Li Shimin was not a martial artist at the same time, and Wenzhi Wugong also made a prosperous sample of the rule of Zhenguan to posterity. However, Tang Taizong Li Shimin, like all emperors, hoped that his country and mountains would be passed on for generations. I always want to spy on the heavenly opportunity and know the geometry of Datang's national fortunes.
So there was Tang Taizong ancestor who enjoyed the prosperity and peace at the same time, and at the same time constantly looked for strange people and strangers, hoping to see through the Heavenly Dao. Therefore, it is not surprising that Li Chunfeng and Yuan Tiangang, two strange people, can enter the palace and accept the emperor's personal treatment.
Folk legends about these things are also very rich, such as the legend of breaking horses into the river and breaking dragon veins for thousands of years. And the very mysterious "pig on the tree, the Tang Dynasty died".
In fact, li Shimin of Tang Taizong, recorded in the official history books of the Tang Dynasty, asked the two masters more than once, the geometry of the fortunes of the Tang Dynasty. The two masters were asked by the emperor so that they could not do anything, so they made a very famous historical deduction. This is the famous "Push Back Map", which has been worshipped by emperors and warlocks of all dynasties for thousands of years, and can be said to be the first book of prophecy in ancient times.
Conclusion: "Pigs on the tree, the Tang Dynasty died" There is a historical passage that says that this sentence is a sentence that Li Shimin still did not rely on and was forced to say helplessly after Yuan Tiangang and Li Chunfeng wrote the "Push back map". And Li Shimin is also very satisfied, because it is impossible for pigs to go up trees!
However, history is so mysterious, the last emperor of the Later Tang Dynasty was killed by the warlord surnamed Zhu, the Tang Empire completely entered history, and the warlord surnamed Zhu was the later Liangwu Emperor Zhu Wen, and it turned out that this pig was not Pi Zhu!
