Chéng Guópéng 程國彭 (zì Zhōnglíng 鍾齡, hào Pǔmíngzǐ 普明子, 1680–1733, 清), early-Qīng physician of Tiāndū 天都 / Shèxiàn 歙縣 (Ānhuī, the heart of the Xīnān 新安 medical school region). The author of the celebrated Yīxué xīnwù 醫學心悟 (1732), the central late-Qīng synthesis of the bā fǎ 八法 (eight methods: 汗、吐、下、和、溫、清、補、消) clinical doctrine that organised internal-medicine practice for two centuries thereafter. After thirty years of practice he retreated to Pǔtuóshān 普陀山, treating workmen during the imperial reconstruction of the monastery, and there composed the KR3ek002 Wàikē shífǎ 外科十法 (1732) as the surgical sixth-juǎn supplement to Yīxué xīnwù. His bāfǎ was widely adopted in Edo Japanese kanpō (Tanba no Mototane and others).
