Gōng Qìngxuān 龔慶宣 (fl. late 5th c., 南朝·齊), Southern-Qí-period editor of the surgical formulary KR3ek040 Liú Juānzǐ guǐyí fāng 劉涓子鬼遺方. The work’s internal colophon dates Gōng’s editorial recension to Qí Yǒngyuán 1 tàisuì jǐmǎo wǔyuè wǔrì = 5 May 499 CE. According to the transmitted xùlùn 序論, Gōng received the manuscript from his older relative Dàoqìng 道慶, who in turn had it from Liú Juānzǐ’s family — and ultimately, on the legendary account, from a “ghost” (the supernatural figure Huángfù guǐ 黃父鬼) shot by 劉涓子 Liú Juānzǐ while hunting in Dānyáng 丹陽. Some modern reference works (including Wikipedia) give Gōng’s lifedates as 550–577 (mid-6th c.), but the internal 499 colophon conflicts with that; either the standard dates are wrong, or the editor is not the same Gōng. The 499 recension date is followed here as the more reliable evidence. Not in CBDB.
