Zhái Zhútíng 翟竹亭 (b. guāngxù yǐmǎo, 1875; death date undocumented), hào Húyuè cūnsǒu 湖岳村叟 (Old Villager of Hú [Lǐ Bīnhú = 李時珍] and Yuè [Zhāng Jǐngyuè = 張介賓]), of Qǐxiàn 杞縣, Hénán. The lineage’s ancestral home was Hóngdòng 洪洞 in Shānxī; the family had been relocated to Qǐxiàn in the early Hóngwǔ reign of the Míng, later moved to Dàzhài village in Chángyuán 長垣 (Zhílì), and returned to Qǐxiàn after the xiánfēng rénzǐ (1852) Yellow River breach at Tóngwǎxiāng 銅瓦廂.
Though he had no formal schooling, he was a disciplined autodidact. At 16 he studied medicine under You Xiàngēng 尤憲庚, a Tōngxǔ 通許 physician then practising at the Qǐxiàn City God Temple, who taught him pulse-theory and acupuncture. After five years he was practising independently. His scholarly orientation was the JīnYuán four masters, the Míng-period epidemic-disease theorist 吳有性 Wú Yǒuxìng (Wú Yǒukě), the Běncǎo gāngmù tradition of 李時珍 Lǐ Shízhēn (Lǐ Bīnhú), and the Lèijīng / orthodox-internal-medicine tradition of 張介賓 Zhāng Jièbīn (Zhāng Jǐngyuè); the latter two physicians supplied his self-chosen hào.
After four decades of rural practice in eastern Hénán — a region that was the most epidemic-prone area of late-Qīng / Republican-period north China — he compiled his selected cases as the KR3ep104 Húyuè cūnsǒu yīàn 湖岳村叟醫案 (2 juǎn, 17 categories, 237 cases), revised jointly by his friends Wèi Guìsēn 衛桂森, Jiāng Jiāmò 江家謨, and Mèng Jìhóng 孟繼鴻, proof-read by his disciples Chén Wényuán 陳文元 and Shī Hépǔ 史和璞, and finally collated and printed by Zhāng Wénfù 張文甫 of Kāifēng Medical College in 1963.
