Chinese archaeological site from about the middle of the Shang dynasty period (18th-12th century BC). The site, located near the confluence of the Yangtze and Han-shui rivers in central Hupei, consists of five graves and two storage pits. It is thought to be the southernmost outpost of the political system in the 15th-13th centuries BC. Palatial foundations, elite burials with Erligang-style bronze ritual vessels, and a hang-tu city wall have been excavated. There are poor burials, pottery, stone tools, and other bronze items. The earliest wood carvings yet found in China were at Panlongcheng.
