Yú Gēnchū 俞根初 (zì Tóngtián 桐田, 1734–1799, 清), Shàoxīng-region Qiánlóng-Jiāqìng-period physician, founder of the Shàoxīng Shānghán tradition that would become central to Zhèjiāng medicine through the late Qīng and Republican periods. His Tōngsú Shānghán lùn 通俗傷寒論 — composed in the late 18th century, circulating in manuscript and local prints — was edited and re-published in the early Republican period by 何廉臣 Hé Liánchén as the Zēngdìng tōngsú Shānghán lùn (KR3ef031, 1916) and Chóngdìng tōngsú Shānghán lùn (KR3ef036, 1934). Lifedates 1734–1799 are conventional. No CBDB record.
