Who is the immortal teacher who really teaches Ye Fa in Maoshan?

Do you want to ask who Maoshan really taught Ye Fashan to be present? As a famous Taoist priest in Tang Dynasty, Mao Shan sincerely taught Ye Fa to preach immortality. Ye Fashan (about AD 6 16-720) was born in Cangxian County (now Lishui, Zhejiang Province). He was a famous Taoist priest in the Tang Dynasty, who could work step by step, eliminate epidemics and apply medicine to save the people. Ye Fashan is proficient in Fu 'an, astrology, divination, Sanskrit, Yin and Yang, and is good at Yin and Yang geography. He was born in an official family. He was smart and studious since childhood, and he was familiar with classics and history. He became a child at the age of 15. Emperor Taizong lived in Zhenguan for five years (63 1), and he went to Gai Hua to repair the Yellow Equator. In the second year of Emperor Xuanzong of the Tang Dynasty (7 14), Ye Fashan was called into the DPRK and was highly respected. He successively assisted five emperors, namely Tang Gaozong, Wu Zetian, Tang Zhongzong, Tang Ruizong and Emperor Xuanzong of the Tang Dynasty, and experienced seven prosperous times, so he was called the "Emperor of the Tang Dynasty". In the fifth year of Kaiyuan (7 17), Ye Fashan was ordered to enter Beijing. When Yang Guifei was slightly ill, she could not be cured for a long time. Ye Fashan secretly asked the old man to write thirty volumes of the book "Jade Qing Wuji Always True Wenchang Cave True Sutra", one of which was transferred to study, but she was ill ten days ago.
