The Tomb of Yan Can is located at Huangfenzui, Yong'an, Longping, Zunyi County, Guizhou Province. It has a flat roof and two chambers built of white sandstone bars, covering an area of 540 square feet. The two chambers are par­allel, the southern cham­ber holding Yang Can and the northern his wife. Both chambers consist of a door, a front compartment, and a back compartment, and the two are connected by an aisle. On the back wall of the southern chamber is an eye-catching painting called Gongshitu ("Picture of Pay­ing Tributes"), which reveals the connections between the central government and the ethnic minorities of the bor­der areas at that time.
