Shangqing practice values meditation techniques of visualization and breathing, as well as physical exercises, as opposed to the use of alchemy and talismans. The recitation of the sacred canon plays an equally important role. The practice was essentially individualistic, contrary to the collective practices in the Celestial Master school or in the Lingbao School. Recruiting from high social classes, during the Tang Dynasty, Shangqing was the dominant school of Daoism, and its influence is found in literature of the time period. The importance of the school only began to diminish beginning from the second half of the Song dynasty. Under the Yuan dynasty, the movement was known by the name Maoshan and the focus changed from meditation to rituals and talismans. In the 21st century, Maoshan Daoism is still practiced but its current techniques are very different from the original techniques developed at the beginning of the school.
