Huangdi Neijing is divided into Lingshu and Suwen, which is the earliest medical classic in China. One of the four classic works of traditional medicine is Difficult Classic, Treatise on Febrile Diseases and Shennong Herbal Classic.

Huangdi Neijing is a comprehensive medical work, which establishes the theories of Yin and Yang, five elements, pulse condition, Tibetan image, meridians, etiology and pathogenesis, symptoms, diagnosis, treatment, health preservation and luck.

Discussing medicine in a holistic view presents a "holistic medical model" of nature, biology, psychology and society (according to the research of modern scholars, it is considered that the traces of Huang family in this edition are invaded by Taoist priests in Sui and Tang Dynasties). Its basic material comes from the long-term observation of life phenomena in ancient China, a lot of clinical practice and simple anatomical knowledge.

Huangdi Neijing is the earliest and most influential medical classic in China. The compilation of Huangdi Neijing marked the formation of the theoretical system of traditional Chinese medicine, laid a solid foundation for the development of traditional Chinese medicine in recent years, and occupied an important position in the medical history of China, and was honored as a "family of physicians" by later generations.

The origin of the name

Han Shu Literature and Art Annals Ji Fang contains four Chinese medicine classics: Medical Classic, Classic Prescription, Immortal and Zhong Fang, while Huangdi Neijing is included in Medical Classic.

The so-called "medical classics" is a book that expounds medical theories such as human physiology, pathology, diagnosis, treatment and prevention. It is called "Beijing" because of its importance. The ancients called important books that had certain rules and generally had to be studied "classics", such as the Confucian Six Classics, Laozi's Tao Te Ching, and the simple three-character classics.

The reason why it is called "Neijing" is not that "Yin and Yang of the five internal organs are called" internal "in Wu Kun's Su Wen Zhu and Wang Jiu's Neijing Jing Lun He", nor that "the internal is the way to deal with the world" in Zhang Jiebin's Jing Lei, but just opposite to "external".

This is similar to Liezhuan, Liezhuan, Chunqiu and Liezhuan of Chunqiu, Neipian and Waipian of Zhuangzi, Neizang and Waizang of Han Feizi, but Huangdi Neijing and Baibai.
