Artist's horse painting features on postage stamp set

Ren Renfa was a hydraulic engineer who overlooked major projects for the Yuan Dynasty (1271-1368) court he served, but today, he is better known as a great painter celebrated for his meticulous portrayal of horses. Now his works are spread across museum collections, including Chu Yu Tu (Coming out of the Stable), a prominent handscroll painting measuring some 2 meters in length.
