Why can Pulse Classic lay an important foundation for the development of pulse science in later Chinese medicine?

Wang Shuhe, a doctor in Jin Dynasty, wrote the Pulse Classic, which is the earliest extant monograph on pulse science in China. This book is a systematic summary of pulse science before the 3rd century, with the number of volumes 10. Excerpts from Neijing, Difficult Classics, Treatise on Febrile Diseases, Synopsis of the Golden Chamber, Bian Que and Huatuo, expounds and analyzes pulse science and pulse method, and puts forward his own opinions. In the book Pulse Sutra, Wang Shuhe divided the pulse condition into 24 types for the first time, such as floating, bleeding, slipping, counting, increasing, string, tight, sinking, squatting, skin, solid, slight, astringent, fine, soft, weak, weak, scattered, slow, late, knot, generation and moving. They were sorted and compared in 8 groups, and the location diagnosis of left-hand inch pulse dominating the heart and small intestine, closed pulse dominating the liver and gallbladder, right-hand inch pulse dominating the lung and large intestine, closed pulse dominating the spleen and stomach, and double-hand foot pulse dominating the kidney and bladder was preliminarily confirmed, which laid an important foundation for the development of pulse science in later Chinese medicine.
