Sūn Wěi 孫偉 (fl. late Kāngxī era, ca. 1670–1720), Qīng clinical-pharmacology compiler. Compiler of the Liángpéng huìjí jīngyàn shénfāng 良朋彙集經驗神方 (KR3ed147) in 6 juǎn, with a distinctive opening section on obstetric emergencies (Jíjiù xiānfāng 急救仙方) prefaced by Xú Shǒuzhēn 徐守真 of Jīnchuān 金川. The work’s editorial principle is the avoidance of cǒng / pì / guì (cumbersome / rare / expensive) ingredients in favour of formulas accessible to the rural poor — especially for the high-priority obstetric-emergency cases. Sparse further biographical record.
