Yuan Tiangang was a metaphysician at the end of Sui Dynasty and the beginning of Tang Dynasty. He was remembered for his accurate fortune-telling. When he first came to Luoyang in the Tang Dynasty, he was sought after by many people and became famous. As we all know, Yuan Tiangang gave Wu Zetian a photo when she was just born. When Yuan Tiangang met her for the first time, she said that Wu Zetian had an extraordinary face and might become the son of heaven when she grew up. As a result, every sentence came true, and Wu Zetian became the only female emperor in history.
Yuan Tiangang was born in poverty in history and suffered a lot for his life since he was a child. However, Yuan Tiangang didn't become very depraved, instead, he was very self-motivated. It is also through his efforts that he is proficient in various skills, especially metaphysics, and is very talented. Later, he was worshipped by Rip and Sun Simiao, the demon king. His medical skills and facial features were so fierce that Emperor Taizong admired him and summoned him personally, while Yuan Tiangang stayed in Chang 'an.
In the twelfth year of Zhenguan, a vision appeared in the sky and a white star appeared in broad daylight. Emperor Taizong was very upset, so he asked Yuan Tiangang to budget for good or ill luck. After many days' research, Yuan Tiangang finally summed up "the unfavorable omen, symptom and generation of Taibai Games", which can only be renamed as "push back map". I believe there is no one who doesn't know. Yuan Tiangang's metaphysical skill is really perfect, which makes people really admire him. No wonder Emperor Taizong valued him.
But Yuan Tiangang later realized that if he stayed in Chang 'an, he might be killed, so he resigned and returned to China soon. He was buried in Baiheshan after his death, but people are also puzzled about the cause of his death. Some people say that he did not die, but became an immortal. Others think that he has lived for 300 years and has reached the point of death. But in any case, although metaphysics is powerful, we should believe in science more.
