In order to unify the north and consolidate its position in the Central Plains, the Northern Wei Dynasty used the whole people as soldiers. At that time, since monks had always been exempted from taxes and corvee, Emperor Taiwu, who was keen on martial arts, issued an edict in the fourth year of Taiyan (438) that all monks under the age of 50 would return to the secular world and perform military service. He also listened to the calumny admonition of Prime Minister Cui Hao, converted to Kou Qianzhi's Tao of Tianshi, rejected Buddhism, and gradually developed into an action to destroy Buddha.

Cui Hao was born in a famous family, read the history of scriptures, and was good at the study of yin and yang and five elements and arithmetic. He lived through the three emperors of Shi Dao, Ming Yuan Emperor, and Emperor Taiwu Emperor. He often participated in military and political secrets and was deeply trusted by Emperor Taiwu. After meeting Kou Qianzhi, he believed in Taoism and accepted his spells. In his early years, Kou Qianzhi was enthusiastic about Immortal Dao and practiced the Wudoumi Dao founded by Zhang Ling, Zhang Heng, and Zhang Lu at the end of the Han Dynasty. He followed the alchemists to Huashan and Songshan to learn Taoism. He claimed to have been granted the position of a heavenly master by the supreme ruler and twenty volumes of "Yunzhongyin Reciting the Commandments of New Science". At the end of Emperor Yuandi of the Ming Dynasty, Kou Qianzhi entered Pingcheng from Songshan Mountain and made friends with Cui Hao. He often listened to Cui Hao talk about the history of ancient chaos all night Later, Kou Qianzhi absorbed Confucianism, Buddhist scriptures, fasting and sacrificial rituals into Taoism, and rebuilt the Wudoumi Dao, hoping to make it easier for the emperors of the Northern Wei Dynasty to accept.

In the early years of the reign of Emperor Taiwu, Kou Qianzhi presented a book on Taoism, but there were very few people in the government and the public at that time. Cui Hao wrote a letter to dissuade Emperor Taiwu, so that Emperor Taiwu believed in Taoism and sent people to sacrifice to Mount Song Mountain. Emperor Taiwu also established Tianshi Daochang in the southeast of Pingcheng, calling himself the Taiping True Lord. He personally received talismans and built the Jinglun Celestial Palace to worship the Taiping True Lord. He changed the year name to the Taiping True Lord, and became a full Taoist.

Emperor Taiwu's action to abolish Buddhism began with the suppression of Buddhist monks in the fifth year of the Taiping Emperor (444). He ordered that all people, from princes to common people, be prohibited from privately raising Buddhist monks, and that they hand over the hidden Buddhist monks within a time limit. If they hid anything, they would destroy the entire sect. The following year (445), Gai Wu, a barbarian from Lushui, revolted in Xingcheng (Huangling, Shaanxi), with more than 100,000 people. In seven years, Emperor Taiwu personally led his troops to suppress it. When he arrived in Chang 'an, he found weapons in a temple. He suspected that the monk was colluding with Gai Wu. He was furious and ordered the killing of the entire temple monks. Cui Hao took the opportunity to persuade the emperor to destroy Buddha, so Emperor Taiwu further implemented the harsh policy of abolishing Buddha: killing the monks in Chang 'an and burning all Buddhist statues in the world. For a moment, the whole country was in turmoil.

On March 15, 446 (the second day of February of the seventh year of Taiping Senior Monarch in the Northern Wei Dynasty), Emperor Wei Dawu ordered: "First destroy the sky and the sand gates, and destroy the statues of the Buddhas. Anyone who dares to speak of Buddhism in the future will be slashed all over the door!"

At that time, the crown prince Tuoba Huang was in charge of the country and had always believed in Buddhism. He repeatedly put up the list and discouraged Emperor Taiwu. Although they were not accepted, it was also because of this that the edict to abolish the Buddha was delayed, and the sand gates near and far were spared from hiding when they heard the news. Buddha statues and scriptures were also hidden in secret; however, none of the temples and pagodas in the territory of Wei were spared, and history said that Taiwu Dharma was difficult. Shortly after the abolition of the Buddha, Kou Qian died of illness, and Cui Hao later wrote the "History of Wei", in which he was cut in half for contempt of the Hu people, and more than 100 of his people were executed. Six years after the abolition of the Buddha, Emperor Taiwu died, Emperor Wencheng ascended the throne, and the edict was issued to revive Buddhism, and Buddhism gradually resumed development.
