The Dian'an Ruins

　　Located around the Dian'an Pagoda in Zhangtan Township of this county, the ruins were discovered during the 1981 cultural relics survey. They lie to the north of the Han River and to the west of the Huangyang River, approximately 80 meters above the riverbed, and belong to a loess mound terrain. The central part of the ruins lies beneath the foundation of the Dian'an Pagoda, and the surface is farmland, where stone tools and pottery fragments are occasionally unearthed during farming.

　　Artifacts collected include stone axes, stone adzes, stone chisels, stone hoes, and clay red pottery bowls and jars. Most of the stone tools are either chipped or flaked, with the most representative being the broad-mouthed, clamp-bodied hoes of various sizes.
