Yáng Jùn 楊濬 (zì Yùhuái 玉懷, hào Lìshān 栗山, conventionally cited as Yáng Lìshān 楊栗山, 1705–1795, 清), Sì-chuān-region Qiánlóng-period physician, one of the most important late-18th-century writers on wēnyì 瘟疫 (warm-epidemic) disorders. Native of Hèyáng 郃陽 (Shǎnxī) by some sources; his career was in Sìchuān. He lived through the period of recurrent epidemic outbreaks in the southwest, and his clinical experience informed the major work:
- Shānghán wēnyì tiáo biàn 傷寒瘟疫條辨 (KR3ef050, 6 juan, 1784) — also titled Hányì tiáo biàn 寒疫條辨 in some editions.
Yáng’s doctrinal program integrates the Shānghán canon with the late-Míng / early-Qīng wēnyì tradition of 吳又可 Wú Yòukě, 戴天章 Dài Tiānzhāng, and 葉桂 Yè Tiānshì, providing a synthetic clinical framework for managing both cold-damage and warm-epidemic outbreaks. The work was widely cited by the 19th-century epidemic-medicine writers (notably 王士雄 Wáng Shìxióng / Wáng Mèngyīng). Conventional lifedates 1705–1795 sometimes given as 1706–1794.
