Huangdi Neijing is divided into two parts: Lingshu and Su Wen. It was written by an ancient physician named Huangdi in Xuanyuan, and was jointly created by physicians and medical theorists. It is generally believed that it was written in the Spring and Autumn Period and the Warring States Period. While expounding the pathogenesis and pathology in the form of dialogue between Huangdi, Qi Bo and Lei Gong, he advocated that the disease cannot be cured, but not cured, and at the same time advocated health preservation, life preservation, longevity and longevity. It is one of the four classic works of China traditional medicine (Huangdi Neijing, Difficult Classic, Treatise on Febrile Diseases, Shennong Herbal Classic), and the earliest existing medical classic in China medical treasure house. It is a medical masterpiece that studies human physiology, pathology, diagnostics, therapeutic principles and pharmacology. Theoretically, the theory of Yin-Yang and Five Elements, the theory of pulse condition and the theory of zang-xiang in TCM are established. Huangdi Neijing, referred to as Neijing for short, is one of the earliest existing medical classics in China. Written from the Warring States to the Qin and Han Dynasties, it is a summary of the long-term experience of working people in China in fighting diseases. Its appearance created a unique theoretical system of traditional Chinese medicine, marking the development of traditional Chinese medicine from the stage of simply accumulating experience to the stage of systematic theoretical summary.

Huangdi Neijing is a classic work that comprehensively discusses the theory of traditional Chinese medicine. Based on ancient anatomical knowledge and guided by ancient philosophical thoughts, his book gradually developed from perceptual to rational, from fragment to synthesis through long-term observation of life phenomena and repeated verification of medical practice. Therefore, under the guidance of ancient simple materialist dialectics, this theoretical system put forward many important theoretical principles and academic viewpoints, which laid a solid foundation for the development of traditional Chinese medicine.
