CAM collects more than 200 items of stoneware of the Neolithic Age: stone axes, stone adzes, stone chisels, stone shovels, stone saddle-querns and holystones, which were mainly farming tools and implements and which form a themed exhibition of prehistoric agricultural implements. Among the collection are prehistoric farming tools unearthed from the Cultural Ruins of Longshan and Hongshan. It is worth mentioning that more than 40 unearthed historical relics from the Culture Ruins of Cishan and Peiligang are collected by, and displayed in, CAM.
