The school's doctrine is related in the works of the school's founders: "Common Teachings of Immortals and Buddhas" and "True Principles of Heavenly Immortality" by Wu Chongxu; and also in "Book of Understanding Life" and "Confirmatory Teachings of Golden Immortals" by Liu Huayang. The school puts its main emphasis on the practice of internal alchemy, in order to realise Tao, thus achieving a status of "an immortal and a buddha". A distinctive trait of the school is its postulated identity of Taoist principles with those of early Chan Buddhism. As E. A. Torchinov noted in the foreword to his translation of Zhang Bo-duan's "Chapters of Understanding Life", "With time the immortals came to be regarded as taoist counterparts of Buddhas, which have led to creation of syncretical schools of Immortals and Buddhas in 16th-17th centuries; in these schools tenets of Buddhist doctrine were only perceived through the lens of taoist tradition."
Translated canons
The only canon of the school translated and printed in several European languages is the "Book of Understanding Life" by Liu Hua-yang. It was first translated into German and published in 1926 under the title of "Liu Hua Yang, Hui Ming King. Das Buch von Bewusstsein und Leben". Later this German translation was translated into French, and printed in 1934 with title of "Lieou Hua Yang. Le Livre de la Conscience et de la Vie". The Russian translation was made by V.V Maliavin and was included into "Ascending towards Tao: a Compendium " under the title of "Book of Consciousness and Life". There is also a direct translation by Eva Wong, titled "Cultivating the Energy of Life".
The Wu-Liu Pai school was established in 16th-17th centuries at the time of Ming dynasty being succeeded by the Qing dynasty. The founders of the school are believed to be the Taoist Wu Chung-xu initially from the Dragon Gate school, which is a sub-sect of the Complete Reality school; and his student Liu Hua-yang, a Chanmonk who converted to Taoism; both were originally from Yuzhan.
One of the more widely known of such lines of transmission is the Qian Feng Pai or Thousand Peaks school, whose popularity stems from a book by Zhao Bi-chen "Secrets of cultivation of Life and Destiny". This book was translated into English by Lu K'uan Yu, known also as Charles Luk and published under the title "Taoist Yoga, Alchemy and Immortality". The orthodox Wu-Liu Pai school does not recognize Qian Feng Pai as preserving the full transmission.
