Wú Zhènglún 吳正倫 (hào Chūnyán 春岩, fl. mid-16th c., Míng), physician from Shèxiàn 歙縣 in Huīzhōu 徽州 prefecture, Anhuī. Originally a candidate for the examinations, he turned to medicine on account of recurrent illness and apprenticed himself to the prominent Húzhōu physician Lù Fūyě 陸膚野 (one of the principal late-Ming inheritors of the Dānxī 丹溪 [Zhū Zhènhéng] tradition). Practised for years across the Lower Yangtze and into the HuáiBěi region, and spent four years in residence in Línqīng 臨清 in northern Shāndōng, where the local merchant community sponsored the compilation of the Yǎngshēng lèiyào 養生類要 (KR3eo004, preface 1564). He is also credited with the Línzhèng zhǐzhǎng 臨證指掌 and Zhūzhèng biànyí 諸證辨疑. CBDB 684442 carries no lifedates; modern genealogical-source reconstructions propose c. 1529–1568.
