Sūn Wényìn 孫文胤 (zì Duìwēi 對薇, late-Míng), Xīn-ān-born physician active in the Zhènjiāng 鎮江 region. His clinical practice spanned the lower Yangtze, with frequent consultative travel to Sūzhōu and Hángzhōu. Sūn’s principal work is the Dāntái yùàn 丹臺玉案 (KR3er044, composed c. 1625–1636), a six-juǎn late-Míng clinical compendium that self-consciously synthesises the SòngJīnYuán four-master tradition with the Língshū / Sùwèn canonical literature, the Huángtíng nèijǐng Daoist physiological tradition, and the Màijīng of Wáng Shūhé. Sūn’s biographical detail is otherwise sparse; he is recorded in some late-Míng / early-Qīng catalog records as a Xīnān-born physician of Zhènjiāng. No CBDB record. Lifedates undetermined.
