龍山文化
Techniques of pottery-making are marked by a fine red ware and a coarse reddish-brown ware. There are also a few pieces of grey ware. They are handmade, there being no evidence of wheel-made ware. While the Qijia culture pottery has its own stylistic characteristics, it also shares many traits in common with the Longshan culture in Shaanxi. Some elements of the Majiayao culture are also present.
