Yuan Tiangang's specialty, people of what era?

Yuan Tiangang, an astronomer, astrologer, forecaster, feng shui master, Taoist priest and fortune teller in the early Tang Dynasty, was born in Chengdu, Yizhou (now Chengdu, Sichuan). Being good at study style, he was so tired that he was ordered by Yan Guan in Sui Dynasty and Huojing (Lin Qiong) in Tang Dynasty. He is the author of Six People's Journey, A Picture of Five Elements, Three Generations of Photography, TuiBei (Li) and Yuan Tiangang's Ode to the Bone. There is a volume of Yi Xuan Jing Yao in Tongzhi Shi Lu. Nine one. Gao Yuxiang, the founder of the contemporary Yiyang School, commented on Yuan Tiangang: "The name is like a bright moon covering a thousand years, and the sound is like Lei Zhen in ancient and modern spring."

Yuan Tiangang once met Du Yan, Wang Jue and Wei Ting in Luoyang, and predicted that Du Yan would be famous for his articles.

Wang Jue has been an official for five years; Wei Ting, eyeing the military attache. It is also predicted that all three people will be condemned after they become officials, and then everyone will meet again. Sure enough, during the Wude period in Tang Gaozu, Du Yan was elected as a Ce Tian bachelor as an imperial adviser. Prince Li recommended Wang Jue as Prince Zhongyun and Wei Ting as military attache. When their official career was smooth, three people were accidentally exiled to our state by a palace coup, and they met Yuan Tiangang again here. Yuan Tiangang once again predicted to his face that "fairness will eventually be expensive", and finally, all officials were promoted to the third class. The future and ending of the three people have indeed been verified. In the early years of Emperor Taizong's Zhenguan, Yuan Tiangang was famous for his physiognomy prediction. Li Shimin, Emperor Taizong of Tang Dynasty, summoned Yuan Tiangang and praised his profound skills. He asked him, "There was Junping (Yan Junping, a master of martial arts in Han Dynasty) in ancient times, but now I am famous. What? " Yuan Tiangang replied that Yan Junping was born at a bad time, and I am much better than him! In Jiucheng Palace, he was asked to visit fortune tellers Zhang Hangcheng, Ma Zhou and others, all of whom were important officials in Zhenguan, and all his predictions were accurate.

According to legend, Emperor Taizong ordered Yuan Tiangang and Li, the famous astrologers at that time, to compile China's first wonderful book "Pushing a Cup". Li calculated with Zhouyi Bagua. Unexpectedly, he was addicted and out of control. He actually calculated the fate of China for more than two thousand years after the Tang Dynasty, until Yuan Tiangang gave him a push and said, "Let's go back and rest." Therefore, this wonderful prophecy book was named "TuiBei Map". There are sixty images in TuiBei Tu * *, and each image is accompanied by a prophecy and a poem "Yue Ode", which predicts the major events in China's history from the Tang Dynasty to the future world harmony.
