郑钦安

Zheng Qin'an is an important author in the field of traditional Chinese medicine. Public information about his life, nationality, and dates of birth and death is limited. From his surviving works, it is clear that he devoted himself to expounding the classical theories and clinical principles of Chinese medicine. His representative works include Yili Zhenzhuan (True Transmission of Medical Principles), Shanghan Heng Lun (A Constant Discourse on Cold Damage), and Yifa Yuantong (A Comprehensive Guide to Medical Methods). All three have been circulated in large-print recitation editions to help readers study and memorize them. His writing centers on the origins of medical theory, Cold Damage scholarship, and clinical diagnosis and treatment. It emphasizes classical annotation and theoretical coherence, making it suitable as reference material for beginners and for the study of medical classics. Although records of Zheng Qin'an's personal experience are scarce, his works have had a certain influence on the transmission of Chinese medical scholarship and are often classified as medical readings for learners to recite and reflect upon.
