The Mengzhuang site lies on a terrace east of Mengzhuang town in southeastern Huixian city, Henan, and occupies an area of 300,000 sq m. It was excavated in 1992-1995, which led to the revelation of remains of the Peiligang, Yangshao, Longshan and Erlitou cultures. Those of the Longshan culture include one city-site, 16 house-foundations, numerous ash-pits and four wells. Among the unearthed Longshan objects are: stone tools - the axe, spade, adze, knife, arrowhead, and chisel; bone implements - the arrowhead, awl, chisel, and spoon ; shell artifacts - the knife and arrowhead ; and pottery-the jar, yah steamer, jia tripod, gui tripod, urn, zeng steamer, basin, vessel stand, cup, vessel cover, bowl, dou stemmed vessel, ring-foot dish, zun-shaped object, li tripod and ding tripod. The whole complex can be divided into two phases, which are dated to 2400--2300 and 2300--2100 BC respectively.
