Reference ancient books of TCM diagnostics

Introductory books on pulse diagnosis of traditional Chinese medicine (personally recommended) ancient books can be found in "Pulse Studies in Hu Ling" written by Li Shizhen in Ming Dynasty, as well as famous introductory books on traditional Chinese medicine in ancient and modern times. The forms of songs and rhymes are easy to understand and recite, and now there are many works translated and explained in vernacular Chinese. The first edition of Pulse of Modern Chinese Medicine written by Professor Liu Guanjun, a famous old Chinese medicine practitioner, has published nearly 200,000 copies. The theory in the book is detailed, combining personal experience with famous medical records, integrating theory with practice, and there are various pulse diagrams and similar pulse comparison diagrams, with rhymes in ancient books such as Hu Ling Pulse Classic. This is a good study book on pulse diagnosis. Not much reading, but good, especially suitable for beginners. Moreover, the pulse chart can only help you understand a little, and practice is the most important thing. The ancients summed it up well: "More pulse-taking" and "More clinical experience is better than reading more Wang Shuhe".
