Wáng Huàzhēn 王化貞 (?–1632 明), late-Míng official, military commander, and amateur physician. Native of Lángyé 琅琊 (Shāndōng). Jìnshì of Wànlì 39 (= 1611). Best known as the Guǎngníng xúnfǔ 廣寧巡撫 (Governor of Guǎngníng, Liáodōng front, 1621–22) who lost the Battle of Guǎngníng to the Manchu forces of Núrhachi in early 1622, was disgraced, and was eventually executed in 1632 along with his commanding co-defendant Xióng Tíngbì 熊廷弼. He is one of the principal villains in standard late-Míng military histories (cf. Míngshǐ j. 259).
Three years before the Guǎngníng disaster, in 1618 (Wànlì 46), Wáng issued the Chǎnjiàn 產鑑 (KR3ei050), a two-juǎn late-Míng obstetrical compendium framed as a Confucian-charitable household manual for women’s safety in childbirth. The 1618 work is a documentary record of late-Míng official-class engagement with humanitarian household medicine. The work survives in multiple Qīng-period reprints. No CBDB entry. The biographical detail in standard reference works centers on the military disaster rather than the medical writing.
