Péi Yīzhōng 裴一中 (hào Zhàoqī 兆期, often referenced as Péi Zhàoqī 裴兆期), early-Qīng physician of Hǎiníng 海寧 (Zhèjiāng), active in the late Míng — early Shùnzhì era. Author of KR3eq040 Yányī 言醫 (compiled 1657 Shùnzhì shísì nián dīngyǒu 順治十四年丁酉), an early-Qīng medical-philosophical treatise distinguished by its methodological aphorisms on the physician’s clinical responsibility rather than by doctrinal-clinical specifics. Doctrinally a moderate inheritor of the 趙獻可 Zhào Xiànkě Yīguàn 醫貫 warming-tonifying line, but transcending doctrinal partisanship in his broader reflection on the integration of Confucian moral cultivation with medical practice. The Yányī’s opening four-part aphorism (xué bùguàn jīngǔ, shí bùtōng tiānrén, cái bùjìn xiān, xīn bùjìn fó zhě) became proverbial in late-Qīng / Republican Chinese medical literature. His parallel KR3eq072 Péizǐ yányī 裴子言醫 is the same work in a different transmission. Catalog meta dates him conventionally to the Míng (the early Shùnzhì composition would also be Míng-rebel-period from a Ming-loyalist perspective). Not in CBDB.
