Early-Qīng (Shùnzhì / Kāngxī-era) physician of Shèxiàn 歙縣, Huīzhōu (Ānhuī), and a member of the Xīnān 新安 medical lineage. His principal extant work is KR3er103 Yījīn yī fá 醫津一筏 (c. Kāngxī 1 / 1662), a one-juǎn treatise in fourteen essays on the zhìfǎ 治法 (therapeutic-method) passages of the Nèijīng; a separately-attested Nèijīng shìyào 內經釋要 may be the same work under another title. The Yījīn yī fá was later pirated and re-attributed as KR3er105 Yījīng mìzhǐ 醫經秘旨, with the original authorship not securely restored until Gāo Sīqián’s 1925 philological investigation for the Sānsān yīshū 三三醫書 series. His zì is given as Hánzhēng 含徵 in most sources but as Hánwéi 含微 in the Sìkù quánshū zǒngmù tíyào. Not in CBDB.
