Brief Introduction Chinese Name: 柯琴 (Kē Qín) Alias: Sifeng (似峰, Sì Fēng) Style Name: Yunbo (韻伯, Yùn Bó) English Name: Ke Qin (family name first) or Qin Ke (given name first) Hometown: Cixi Dates: c. 1662–1735 CE Major Works: 《傷寒論註》(Shang Han Lun Zhu, or Annotations on the Treatise on Cold-Induced Diseases),《傷寒論翼》(Shang Han Lun Yi, or Supplementary Treatise on Cold-Induced Diseases),《傷寒附翼》(Shang Han Fu Yi, or Additions to the Treatise on Cold-Induced Diseases). Representative Work: Shang Han Lai Su Ji. Biographical Introduction and Historical Accounts
Ke Qin, a Qing dynasty scholar of Shang Han Lun (The Treatise on Cold-Induced Diseases), used the aliases Yunbo (Yùn Bó) and Sifeng (Sì Fēng); his self-chosen literary name was Sifeng. He was a native of Cixi (present-day Zhangting, Yuyao). A native of Cixi (present-day Zhangting Town, Yuyao City, Zhejiang Province), he was well-versed in classical literature and skilled in composing poetry and "ci". Having abandoned preparation for the imperial civil service examinations, he devoted himself to the study of medicine despite his family’s poverty. He traveled to the Wu region and settled in Yushan. Reserved about his medical knowledge, he remained relatively unknown during his lifetime. His approach—“naming syndromes after prescriptions and classifying syndromes according to prescriptions”—is clinically pragmatic and profoundly influenced later studies of Shang Han Lun. Little biographical detail survives; available records identify him as both a Confucian scholar and a highly competent physician. He died in Yushan in his old age.
Major Works and Academic Contributions
Ke Qin deeply studied foundational texts such as Nei Jing (The Inner Canon) and Shang Han Lun (The Treatise on Cold-Induced Diseases). Among his works are medical treatises and annotated compilations. He compiled Nei Jing He Bi (Two-Piece Jade Combination of the Inner Canon, or A Harmonized Compilation of the Inner Canon), now lost. His extant major works include Shang Han Lun Zhu Annotations on the Treatise on Cold-Induced Diseases), Shang Han Lun Yi (Supplementary Treatise on Cold-Induced Diseases), and Shang Han Fu Yi (Additions to the Treatise on Cold-Induced Diseases). These three were later collected and published together as Shang Han Lai Su Ji (Renewal of the Treatise on Cold-Induced Diseases).
Unlike many contemporaries, Ke Qin did not prioritize textual emendation or philological reconstruction of Zhang Zhongjing’s original text. Instead, he focused on elucidating the core principles of syndrome differentiation ("bian zheng") and treatment ("lun zhi"). Accordingly, he reorganized the text by channel, classified categories according to syndromes, and grouped prescriptions under corresponding syndromes. In each of the six-channel chapters, he first outlines principal syndrome categories, then lists relevant syndromes and prescriptions within each category—including deteriorated cases, mistreated cases, and diagnostic dilemmas.
This method of textual organization is more clinically pragmatic. Inspired by it, later generations of physicians classified syndromes according to therapeutic methods and categorized them by symptom patterns to explore the principles of syndrome differentiation ("bian zheng") and treatment ("lun zhi") in Shang Han Lun (The Treatise on Cold-Induced Diseases) from multiple perspectives. At the same time, Ke Qin rejected the prevailing Tang–Song view that Shang Han Lun was solely a monograph on exogenous febrile diseases. He argued that the six-channel system applies equally to miscellaneous diseases.
Shang Han Lun Zhu (Annotations on the Treatise on Cold-Induced Diseases) is a four-volume work by Ke Qin, completed in 1669 CE. In composing and annotating this text, he systematically revised and annotated Shang Han Lun entry by entry and sentence by sentence. Its distinctive organizational feature is syndrome-centered classification. Each syndrome group consolidates related passages under a unified clinical heading.
Shang Han Lun Yi (Supplementary Treatise on Cold-Induced Diseases) is a two-volume work completed in 1674 CE. Ke Qin critically engaged with earlier Tang–Song editors’ approaches to collation, textual emendation, and reconstruction of Shang Han Lun. Accordingly, Volume I addresses major topics—including cold-induced disease methodology, the six channels, combined syndromes, wind-cold syndrome, warm and heat, warm disease and summer heat, convulsive disorders, dampness diseases—as well as normal pulse patterns and pulse diagnosis. Volume II systematically outlines the six-channel syndromes.
Shang Han Fu Yi (Additions to the Treatise on Cold-Induced Diseases) comprises two volumes devoted exclusively to the prescriptions of Shang Han Lun. It elucidates the indications, mechanisms of action, and clinical applications of each formula by integrating etiology, pathogenesis, and pulse–syndrome correlations.
