Yidongtian Ruins

　　Yidongtian Ruins, located at the southern foot of Niuwangye Mountain east of Yingjia Street in Yingjia Town, is a limestone cave. The entrance faces southeast, about 7 meters above the ground at the mountain base, with a width of over 10 meters and a height of 3 meters. The cave extends

　　more than 50 meters in depth, divided into inner and outer sections. The cultural deposit layer is mainly found in the outer cave, appearing grayish-brown and firmly cemented. Surveys and excavations of the deposit layer have uncovered remains such as snail and clam shells, animal bones, burnt earth, stone tools, and pottery shards. Artifacts collected inside the cave include polished deer antler spears, bone beads, struck whetstone flakes, cord-marked sandy pottery shards, as well as fossils such as deer teeth and animal bones. It is a relatively clear and intact Neolithic human settlement site.
