Chéng Yúnpéng 程雲鵬 (zì Fèngchú 鳳雛, fl. mid-Kāng-xī era, c. 1660–1700), early-Qīng paediatrician and wénzhāng essayist of Húběi (the Chǔ region). Educated under Jiǎng Shènzhāi 蔣慎齋, who praised him as wú Chǔ wénzhāng jùzǐ 吾楚文章鉅子 (a literary giant of our Chǔ region). The preface to his Cíyòu xīnshū 慈幼新書 (KR3ej022) by Zhāng Xīliáng 張希良 of Huángān 黃安 records Chéng’s close association with the eminent Qīng scholar Wèi Bīngshū 魏冰叔 (Wèi Xǐ 魏禧, 1624–1681) of Níngdū 寧都, who famously praised Chéng’s clinical practice as shéndòng biànhuà, dà sì Wǔhóu yòngbīng 神動變化，大似武侯用兵 (its divine transformations like Zhūgě Liàng’s military strategy). Chéng’s reply, Wǔhóu wú qǐ gǎn, wú shī Dèng Yǔ ěr 武侯吾豈敢，吾師鄧禹耳 (I dare not aspire to Zhūgě Liàng; my model is Dèng Yǔ — who claimed never to have wantonly killed a man), is one of the most quoted self-characterisations in early-Qīng medical biography. He also associated with the inner-alchemy adepts Yánlíng èrwǔ shānrén 延陵二五山人 and Huáshān bànlún dàoshì 華山半輪道士. Note: The catalog meta lists Chéng’s dynasty as 明; internal evidence — the praise from Wèi Xǐ (1624–1681) — places him securely in the early Qīng, Shùnzhì — early Kāngxī generation.
