The Shanghan Lun (傷寒論), written by Zhang Zhongjing around 220 AD, is one of the foundational texts of Chinese medicine — the source of the classical formula tradition that continues to inform clinical practice today. Studying it well requires both precise textual understanding and the clinical experience to translate that understanding into practice.

This book distils over 40 years of Dr Wei-Chieh Young’s teaching on the Shanghan Lun into a systematic clinical reference. Written in Traditional Chinese, it covers six-channel pattern identification, formula analysis and clinical application — with sections on textual interpretation, pattern differentiation and comparative formula studies. At 527 pages, it is one of the most comprehensive modern works on the subject available in Chinese.
