Caojiaba Site

　　The Caojiaba Site is located at Renhekou and was a large-scale settlement and brick-and-tile kiln site from the Han Dynasty. Three brick kilns have been discovered, with thousands of painted bricks and diamond-shaped bricks buried underground. These artifacts were not only found in the kilns but also in numerous tombs across the Caojiaba area. The production techniques of the bricks are largely consistent with those of other Han Dynasty pictorial bricks from central China.
