Hé Yuáncháng 何元長 (also 何瑒 Hé Yáng), 1752–1806, native of Chángshú 常熟 (Sūzhōu, Jiāngsū). A leading early-Jiā-qìng Sūzhōu physician of the Hé family medical lineage — one of the longest-running hereditary medical families in late-imperial China, ultimately producing the famous Ménghé Hé branch (after the family’s 1830s relocation). Together with his contemporaries Hé Wǎntíng 何琬亭 (Hé Hóngzhāng 何鴻章) and Hé Shūshān 何書山 (Hé Wénshān 何文山), Hé Yuáncháng was one of the “Hé-family three” of late-eighteenth-century Sūzhōu. Cases survive principally in KR3ep063 Yè Tiānshì Cáo Rénbó Hé Yuáncháng yīàn and in scattered later anthologies. Not in CBDB. Principal English-language coverage: Scheid 2007, Currents of Tradition.
