Chén Wùān 陳勿庵 (fl. mid–late 18th c.) — Qīng physician, teacher of 何榮 Hé Róng (Xìngyuán), who transmitted to him the manuscript of Tāichǎn mìshū (KR3ei054). May or may not be identical with 陳笏庵 Chén Hùān, the named author of the printed work — the two studio-names differ by a single hào character and may represent confusion in the late-18th-century manuscript transmission. Not in CBDB.
