Liáng Kǎi (梁楷) (fl. late 12th-early 13th century) was a Chinese artist who studied with, and then excelled, his master, Jia Shigu . In 1210, he was awarded the rank of Painter-in-Attendance at court, but he refused it. Instead, calling himself "Madman Liang", he spent his life drinking and painting. Eventually, he retired and became a Zen monk. Liang is credited with inventing the Zen school of Chinese art.
