Qín Jǐngmíng 秦景明 (zì Huángshì 皇士, hào Dànxiāngtáng Guǎngyě dàorén 淡香堂廣野道人, late-Míng), physician of the Sūzhōu region active in the late Wànlì / Chóngzhēn eras. The dated self-preface of his principal work Zhèngyīnmàizhì 症因脈治 (KR3er014) is signed Chóngzhēn xīnsì jiāpíng yuè — the twelfth lunar month of Chóngzhēn 14 (January 1642). The Shěn preface narrates Qín as a man of broad classical and historical learning who turned to medicine after failing to obtain office (xī bù dé zhì yǐ yǒu wéi 惜不得志以有為), and who devoted thirty years to medical study before producing the Zhèngyīnmàizhì. His son Qín Zhīzhèn 秦之楨 expanded the work in the early Qīng with additional clinical material; the standard Qīng recension incorporates this addition. No CBDB record. Qín’s lifedates are otherwise unrecovered; the thirty-year preparation reported in the Shěn preface and the 1642 publication date imply a flourishing roughly c. 1580–1645.
