Since Zhang Ling, peasant leaders have often used Tianshi Road to organize and launch peasant uprisings, which made the literati at that time deeply dissatisfied. At the beginning of the Northern Wei Dynasty, Taoism was respected, Buddhism was suppressed, and Kou took the opportunity to reform Taoism. In the second year of Shenrui (4 15), Kou Qian called the Taishang Laojun to visit, conferred the title of "Shi Tian", and gave twenty volumes of "Reciting New Branches on the Cloud" to convey the method of guiding the party; He was ordered to "clean up the orthodoxy, eliminate the three pseudo-laws (referring to Zhang Heng and Zhang Lu), rent rice tax, and combine men and women". "Pay special attention to politeness, and combine it with diet." In the eighth year of Taichang (423), Li Pulin Wen Song Yue, also known as the great-grandson of the old man, was given more than 60 volumes of Rutu Zhen Jing, and was given the secret method of illegally summoning ghosts and gods, then, Yunying, Bashi and Yujiang, so that he assisted the Northern Taiping Zhenjun (Taiwu Toti of the Northern Wei Dynasty) and led ". In the year of Guang Guangyuan (424), he went to Pingcheng, Dewey (now Datong, Shaanxi) and presented a Taoist book to Taizu. Zuo Guanglu's doctor, Ho Choi, praised him as "informative". Taizu ordered the worshippers to present jade and silk to the sacred mountain to Song Yue, and welcomed his disciples on the mountain. The following year, Shi Tian Dojo was set up in the southeast of Yuping City, "emphasizing the five floors of the altar, following the system of its new classics", gathering 120 Taoist priests and praying six times a day. Later, it was called Shi Tian North Road. In the sixth year of Taiyan (440), Kou Qianzhi claimed to be the restoration of the old gentleman and gave Wu Tai the title of Taiping Zhenjun. The emperor believed it and renamed it Taiping Zhenjun. Two years later, Mao was honored at the Taoist altar and made Kou a national teacher. Shi Tian North Road is a great prosperity. At the end of the Northern Wei Dynasty, faith was still strong. The later Zhou dynasty inherited Wei and worshiped Taoism, and every emperor respected Wei Lao.
On the one hand, Kou abandoned the theory and system that can be used in peasant uprising, and opposed the peasants' "calling officials and setting numbers, gathering ants to gather people, destroying fields and land" and "rebelling against the king and killing the country". In addition, advocating "both Confucianism and Taoism", "teaching and educating people, helping the world and saving people", and advocating that ministers are loyal to their sons, husbands are loyal to their wives, brothers respect their brothers, are humble and humble, and abide by the five permanent members are all listed as the contents of Taoist rules and regulations. At the same time, in the struggle between Buddhism and Taoism, he introduced Buddhism to Taoism, publicized the six divisions in the wheel of karma, imitated Buddhist rituals, and advocated building altars, cultivating merits, chanting scriptures and becoming immortals, and practicing commandments. In addition, Kou Qianzhi also reformed the hereditary system of father's death and son's succession, and advocated "giving knowledge by virtue" and "giving knowledge by virtue"; Oppose Taoist officials to ask Taoist people for money to reduce their burden.
According to Taoist legend, The Book of Kou Qian is a gift from God, with more than 80 volumes. It is generally believed that the volume 1 collected by the orthodox Taoist scriptures, that is, the remnant volume of the new discipline chanting in the clouds, is all missing. However, according to the textual research of Tang Yongtong, a close friend, Reading the New Classics in the Cloud is a general term for the books such as the precept of the old gentleman in Taishang and the precept of the old gentleman.
