Huangdi Neijing is divided into Lingshu and Suwen, which is the earliest medical classic in China and one of the four classic works of traditional medicine (the other three are 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, 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 marks the formation of the theoretical system of traditional Chinese medicine, which has laid a solid foundation for the development of traditional Chinese medicine in recent years. It occupies an important position in the medical history of China, and is honored as "the master of physicians" by later generations.

The content of Huangdi Neijing is very extensive, besides medical theory, it also records the knowledge and achievements of ancient philosophy, astronomy, meteorology, phenology, biology, geography, mathematics, sociology, psychology, temperament and other disciplines.

And these knowledge and achievements are infiltrated into medical theory, making this book a multidisciplinary oral work with medicine as the main body. It has been paid attention to by doctors and experts in related disciplines and has become the research object of Chinese and foreign academic circles. Huangdi Neijing, also known as Neijing, is one of the earliest ancient books in China and the first of the four classics of traditional medicine in China.

According to legend, it was made by the Yellow Emperor, hence its name. However, it is generally believed that this book was finally formed in the Western Han Dynasty, and the author was not a single person, but was created by Huang Lao, a doctor in China. As pointed out in "Huai Nan Zi Xiu Wu Xun", the title of "Yellow Emperor" is intended to trace back to the source and worship the original to illustrate the early birth of China medical culture. It's not a moment's talk, nor is it a single hand.
