Cheng Zhi (程知, Chéng Zhī), whose alias was Fu Sheng (扶生, Fú Shēng), was born in Haiyang. He was a distinguished physician and medical scholar of the Qing dynasty. His exact years of birth and death remain unknown. He authored Yi Jing Li Jie (Explanations of the Medical Classics), a foundational commentary on classical Chinese medical texts. Cheng’s central theoretical contribution was his articulation and defense of the view that the pericardium channel ("Xinbao Jing") functions as the Life Gate ("Mingmen").
Major Works and Academic Contributions
Yi Jing Li Jie (Explanations of the Medical Classics) is a seminal work of traditional Chinese medicine compiled by Cheng Zhi during the Qing dynasty and completed in the tenth year of the Shunzhi reign (1653 CE). The text systematically interprets and organizes key concepts from the Nei Jing (The Inner Canon of the Yellow Emperor) into nine thematic sections: Zang-Fu Bian (Differentiation and Explanation of the Zang and Fu viscera), Jing-Luo Jie (Explanation of the Meridians and Collaterals), Xue-Ming Ju (Explanation of Acupuncture Points), Gu-Bu Jie (Explanation of the Skeletal System), Mai-Xiang Jie (Explanation of the Pulse Manifestations), Mai-Li Jie (Explanation of Pulse Theory), Wang-Se Jie (Explanation of Facial appearance and Complexion Inspection), Bing-Ming Jie (Explanation of Disease Names), and Yao-Ming Jie (Explanation of Medicine Names). The book opens with eleven illustrations depicting anatomical and functional concepts central to classical theory—including the Zang and Fu-viscera, the Triple Energizers (San Jiao), the Life Gate (Mingmen), and the Pericardium Channel (Xinbao Jing), and so on. It provides detailed analyses of pulse conditions described in the Nei Jing, such as anomalous pulses, critical pulse patterns, pulses associated with the Eight Extraordinary Vessels, pulses reflecting Yun Qi (the five evolutive phases and six climatic factors), gender-specific pulses (e.g., feminine pulses), and pediatric pulses—each examined individually with clinical context. Among these, Bing Ming Jie discusses twenty-seven diseases and syndromes recorded in the Nei Jing (The Inner Canon), elaborating on their etiologies, pathomechanisms, and diagnostic features. Yao Ming Jie classifies the medicinal substances cited in the Nei Jing into nine categories: jade and stone (minerals and stones), herbs (botanical herbs), woods, animals, insects and fish, fruits, cereals and grains, and vegetables—further graded into three tiers: superior, middle, and inferior. The work is distinguished by its integrated methodology, combining rigorous exegesis of canonical scripture with original clinical and theoretical synthesis.
Cheng Zhi’s most influential academic contribution was his coherent formulation and textual grounding of the theory that the pericardium channel constitutes the Life Gate—a view he developed and expounded throughout Yi Jing Li Jie.
