Zheng Yijiao used to be the five meters gate of the Han Dynasty. After the Yuan Dynasty, it was the general name of Taoist Shangqing School, Lingbao School and Shitiandao School. The orthodox school took Zheng Jing as its main classics and ignored practice. Sacrifice immortals, recite spells, exorcise ghosts, and pray for disaster relief. According to legend, when Zhang Ling founded the sect, he once said that the old gentleman in the Supreme Master gave him the Dharma for three days, "teaching with the Dharma, making a new debut" and "giving him the Dharma of uniting forces, killing evil and counterfeiting, sharing it with all the gods in the world and learning the Dharma".

Quanzhen religion was founded in the early Jin Dynasty.

. Founder Wang Zhongyang, from Shaanxi. Born in a rich local family, he was a small official in the early Jin Dynasty, then resigned and returned to his hometown. In the fourth year of Zheng Long (1 159), he claimed to have met a fairy in Ganhe Town and was given the recipe at that time. He lived in seclusion in Zhong Nanshan for three years. During the Dading period, he went to Shandong to preach. Quanzhen religion regards Tao Te Ching as a must-read classic for believers. The practice method is based on inner alchemy, not supplemented by outer alchemy, and advocates double cultivation, first cultivation of sex, and then cultivation of life. It is believed that the true and natural cultivation is the only correct cultivation method for Taoist practitioners. Only by getting rid of feelings and desires, knowing each other and calming down can we return to simplicity and become immortal. It also stipulates that Taoist priests must become monks, strictly observe precepts, endure humiliation and filth, and suffer for others. Taoist priests are severely punished for breaking the precepts, from kneeling on incense to banishing and dying everywhere.

The obvious difference between Zhengyi religion and Quanzhen religion lies in:

First, orthodox religions are deeply influenced by China's traditional witchcraft, and there are a lot of runes chanting, deifying and exorcising ghosts in religious ceremonies. Quanzhen religion is dominated by Neidan, which basically excludes the influence of witchcraft.

Second, orthodox monks don't have to become monks, and Quanzhen is the first monk in the history of Taoism. From then on, Quanzhen Taoist priests must become monks.
