Lóng Huìtáng 龍繪堂, late-Qīng physician of Yángxià 陽夏 (= Tàikāng 太康, in Kāifēng prefecture, Hénán). Attested only through the 1914 postface to KR3eq093 Chǔnzǐ yī 蠢子醫, which reports him deceased by that date and the Chǔnzǐ yī his “wǎnnián” (late-year) work — a four-juǎn clinical pedagogical compendium in unmetered popular verse, composed to teach his orphaned grandson Duìshān 兌山. The work is unusually localised to the Hénán late-Qīng regional medical voice, otherwise under-represented in the Chinese medical canon. Not in CBDB.
