Yáng Lìshān 楊栗山 (proper name Yáng Xuán 楊璿; 1705–1791) was a Qīng physician of the LiúHéjiān cooling-fire school whose Shānghán wēnyì tiáobiàn 傷寒溫疫條辨 (1784) — often referred to as the Hánwēn tiáobiàn — was the standard differential-diagnosis manual on cold-damage vs warm-epidemic disease. His tiáobiàn schema served as the explicit model for 郭楚賢 Guō Chǔxián’s Diānkuáng tiáobiàn (KR3eh048).
