Liú Kuí 劉奎 (zì Wénfǔ 文甫, hào Sōngfēng 松峰, fl. Qiánlóng – early Jiāqìng, 清). Native of Zhūchéng 諸城 in Shāndōng. Cousin of the prominent Qián-lóng-era statesman Liú Yōng 劉墉 (1719–1804) — Liú Kuí accompanied his cousin Liú Yōng on educational-supervisory missions in Jiāngsū and Ānhuī in his youth, placing his probable birth in the 1720s–1730s.
Studied clinical medicine in Běijīng under Guō Yòutáo 郭右陶 — i.e. 郭志邃, the author of Shāzhàng yùhéng (KR3eg037) — and also reportedly under Huáng Yuányù 黃元御 (1705–1758), a major Shāndōng physician. Read the Nèijīng and Nánjīng carefully and engaged closely with the JīnYuán “Four Masters”. His distinctive doctrinal commitment is to the pestilential-qi (lìqì 戾氣) framework of Wú Yǒuxìng, which he extends and clinically elaborates.
Principal works:
- Sōngfēng shuō yì 松峰說疫 (KR3eg039), 6 juǎn, completed ca. 1785 (Qiánlóng 50; preface by Wáng Shūxiào dated yǐsì 1785, Liú Sīzōng’s preface dated dīngwèi 1787).
- Wēnyì lùn lèibiān 瘟疫論類編 — a topically-rearranged edition of Wú Yǒuxìng’s Wēnyì lùn.
