At a Sarbi (Xianbei) site in Inner Mongolia's Tongliao city, archaeologists have excavated a settlement site, where they discovered a horseshoe. It is the oldest horseshoe found in the confines of modern-day China. The site has the remains of two buildings and over ten ash pits. They yielded many pottery sherds, ironware, stone objects, and animal bones. Many of the pottery pieces were decorated with patterns that have images of horses, yurts? (毡帐), and the sun.
