黄帝内経
Lingshu Jing (), also known as Divine Pivot, Spiritual Pivot, or Numinous Pivot, is an ancient Chinese medical text whose earliest version was probably compiled in the 1st century BCE on the basis of earlier texts. It is one of two parts of a larger medical work known as the "Huangdi Neijing" (Inner Canon of Huangdi or Yellow Emperor's Inner Canon). The other section, which is more commonly used in Traditional Chinese Medicine, is known as the "Suwen" ("Basic Questions").
