任应秋

Ren Yingqiu is an author of works on traditional Chinese medicine. Public information about him is limited, and no systematic account of his life details is available. Judging from the six works held in the collection, his writing centers on the basic theories and clinical diagnosis of Chinese medicine, covering such topics as pulse studies, pathogenesis, tongue diagnosis, yin-yang and the five elements, and the doctrine of circuit qi. Ten Lectures on Pulse Studies, a Vernacular Explanation of the Binhu Pulse Studies, and Chinese Medicine Tongue Diagnosis focus on diagnostic methods: the first sorts out the essentials of pulse theory, while the second explains Li Shizhen's original pulse text in plain language, helping beginners grasp the identification of pulse and tongue signs. Clinical Analysis of Pathogenesis combines pathogenesis theory with clinical cases, reflecting a path from principle to application. Yin-Yang and the Five Elements and Six Lectures on the Doctrine of Circuit Qi organize the philosophical foundations of Chinese medicine and its framework for calculating circuit qi. His writing is analytical and lecture-style, suited to teaching and introductory study, and has had some influence on the popularization of basic knowledge in Chinese medicine.
