Zhèng Fūzhèng 鄭敷政 (hào Héyáng 和陽, fl. 1569 明), mid-Míng physician of Píngqiáo Kūnshān 崑山平橋 (Jiāngsū), marriage-heir to the Xuē 薛 family medical lineage of Kūnshān. Editor and 1569 prefacer of the KR3ei033 Xuēshì jìyīn wànjīn shū 薛氏濟陰萬金書, the gynecological compilation of his wife’s family. Zhèng’s preface (dated Lóngqìng 3 = 1569) explicitly identified certain prescriptions as secret family-transmitted formulae and enjoined his descendants not to share them — an injunction overturned by an anonymous 1701 (Kāngxī 40) editor who arranged the work for general printing.
