The Wang Changsheng 王长生
Paul PengWang Changsheng was a figure of the Tang Dynasty.
He was also known as "Zhenren of Wangwu" (Zhenren: a title for accomplished Taoist practitioners, literally "True Person").
He was a disciple of Zhang Guo (a renowned Taoist immortal in Tang Dynasty legends).
He practiced the Taoist technique of "dual cultivation of couples for elixir refinement" (a specialized Taoist alchemical practice involving mutual energy cultivation between partners to achieve spiritual or physical refinement).
His work Oral Transmission from the Zhenren of Wangwu: The Spiritual Chapter of Secret Formulas for Yin Elixir has been passed down to later generations. (From Yunji Qiqian / Seven Slips of a Cloudy Satchel—a major Taoist scripture collection compiling ancient Taoist texts.)
