The source of the name of Neijing Map
From the content point of view, Neijing Map or Neijing Map is actually very different from the purpose of illustration, of course it has something to do with it. Strictly speaking, the map of Neijing is an anatomical map of human viscera, and its purpose is to show it to people who study human anatomy and the relationship between viscera, and there are obviously rich Taoist health preservation methods in the map of Neijing. In fact, Neijing Tu and Neijing Tu may both originate from the relevant contents of Huangdi Neijing, and the name of Neijing Tu may contain the classic meaning of "Inner alchemy".
