Zhū Yìzhōng 朱翼中
Northern-Sòng physician and wine-making expert, hào Dàyǐn wēng 大隱翁 (“Old Recluse of the Great Hidden”). His original given name was Zhū Gōng 朱肱 (the Yìzhōng is his zì — Chén Zhènsūn’s Shūlù jiětí lists his work under the pseudonym Dàyǐn wēng without giving his real name, perpetuating the confusion in early biographical references; Lǐ Bǎo’s 李保 XùBeìshān jiǔjīng preface clarifies the identity).
Native of Wúxìng 吳興 (Húzhōu, Zhèjiāng). The early-Yuán Shuōfú compilation by Táo Zōngyí preserves Lǐ Bǎo’s preface which describes Zhū as a recluse-author who lived by the Western Lake at Hángzhōu and supported himself by wine-making; later the imperial Medical Academy (Yīxué) was greatly expanded, and Zhū was recruited as bóshì (academician). He was however demoted for the offence of inscribing a Sū Shì 蘇軾 poem on his door — under the post-1093 Jìyuányòu suppression of Sū Shì literary remains, this was treated as a partisan offence — and banished to Dázhōu 達州.
His two surviving works are: (1) the Nányáng huórén shū 南陽活人書 (also called Shānghán lèiyào or Héjiào nányáng huórén shū) — a major Sòng medical synthesis of Shānghánlùn doctrines, composed c. 1107 and printed 1118; one of the most influential post-Zhāng Zhòngjǐng Shānghán treatises; and (2) the Beìshān jiǔjīng 北山酒經 (KR3i0026) — the foundational Chinese monograph on alcohol-making, composed during his Hángzhōu recluse-period c. 1088–1117. The “Beìshān” 北山 (Northern Mountain) refers to a region near Hángzhōu where Zhū had his retreat.
