Chén Jūshēng 陳匊生 (匊 = 掬 jū “to scoop with both hands”) — late-Qīng physician, kinsman of the preface-writer Chén Shùrěn 陳述忍 and member of a literati family with a transmitted medical practice. The conventional dating places him in the Tóngzhì / Guāngxù era (1860s–1890s). His KR3ep030 Zhěnyú jǔyú lù 診餘舉隅錄 (two juǎn) is a minor but representative late-Qīng provincial-literati casebook with a substantial parallel-prose preface. CBDB has no entry; biographical data beyond the work and the preface are not available.
