Xiuzhen Tu

Xiuzhen Tu or the Chart of the Cultivation of Perfection, is a yet-undated map to the human anatomy explained in the context of Xiuzhen, a method to approach spiritual transcendence. The Xiuzhen Tu is thought to be as old as the ''Neijing Tu'' or the ''Chart of Inner Warp'' attributable to the author of Huangdi Neijing, they were traceable to Xiuzhen Shishu . There is no consensus to the exact dating of both charts but Taoist believe they would be as old as the Huangdi Neijing.
