The Shangqing School (Chinese:上清), also known as Supreme Clarity or Highest Clarity is a Daoist movement that began during the aristocracy of the Western Jin dynasty. Shangqing can be translated as either 'Supreme Clarity' or 'Highest Clarity.' The first leader of the school was a woman, Wei Huacun (251-334). According to her Shangqing hagiographers, her devotion to Daoist cultivation so impressed a number of immortals that she received revelations from them 31 volumes of Daoist scriptures which would become the foundation of Shangqing Daoism. Later, Tao Hongjing, a man, (Chinese: 陶弘景) (456－536) structured the theory and practice and compiled the canon. He greatly contributed to the development of the school that took place near the end of the 5th century. The mountain near Nanjing where Tao Hongjing had his retreat, Maoshan (茅山 – fr), today remains the principal seat of the school.
