Qíntóng 勤炵 (hào Kūnhú 崑湖, late-Míng Zhōufán imperial-clansman, late 16th cent.), holder of the title Hǎiyáng wáng 海陽王 within the Zhōu 周 enfeoffment (one of the Míng imperial cadet branches). In his postface dated Wànlì 16 (1588) to 龔廷賢 Gōng Tíngxián’s Wànbìng huíchūn 萬病回春 (KR3er039), the prince narrates that he had received his dukedom in Jiājìng bǐngchén (1556) and had been afflicted by chronic tánhuǒ 痰火 (phlegm-and-fire) disease for thirty years, until in Wànlì bǐngxū (1586) his elder son Cháoshēng 朝陞 had sought out and engaged Gōng Tíngxián, who restored him to health within sixty days. The prince’s patronage was the principal vehicle for the publication of the Wànbìng huíchūn. No CBDB record; the prince is identifiable only through his Hǎiyángwáng title and the dated postface. Lifedates undetermined.
