What is the real identity of Yuan Shoucheng, the most mysterious fortune teller in The Journey to the West?

Yuan Shoucheng is a fortune teller. He is Yuan Tiangang's uncle.

In the ninth session of The Journey to the West, because he could calculate the position of Weihe aquarium and let fisherman Zhang calculate when he could catch fish, King Jinghe was very angry and scared, so he went to Chang 'an to find trouble and asked him to calculate the time of rain.

Yuan Shoucheng was right. The Dragon King of Jinghe River thought a very, very stupid idea, and changed the hours of rain privately, and the result was known by the Jade Emperor. Violate dogma. Wei Zhi was beheaded in his dream.

Extended data:

Yuan Tiangang was a metaphysician, astronomer and Taoist in the late Sui and early Tang Dynasties. He has written many books about physiognomy, astronomical phenomena and geomantic omen, including Nine-day Xuan Nv Six-person Class, Five Elements Physiognomy, Yi Yao, Three Dynasties Physiognomy, Yuan Tiangang Gu Fu, and Anti-image Map of Taibai Games.

But most of them are dead and out of sight. He was ordered by Emperor Taizong to co-write with his disciples to discuss the historical trend. Perhaps the original name of TuiBeiTu is TuiTu of Bai Hui, Zhao Yuntong and Dai Ji.
