The Yaohongzuizi and Beihongzuizi sites excavated in May-August 1994 belong to the Neolithic and Bronze ages. Their Neolithic remains are of the same type, featuring principally cylindrical jars with impressed and incised bow string and zigzag patterns. As regards Bronze Age remains, the vestiges of Yaohongzuizi yielded mainly plain ding tripods, li tripods and jars, while those of Beihongzuizi, large-sized ding, li and jars with incised short lines along the rim and incised nets on the belly. The discovery of the two sites being at a short distance and belonging to the same two ages is of great significance to studying the cultural sequence of the Neolithic and Bronze ages in the Jilin region.
In October 1996 and May 1997, the Jilin Provincial Institute of Cultural Relics and Archaeology and other institutions carried out two seasons of small-scale excavation. The discoveries include a house-foundation and an ash-pit, as well as 56 pottery vessels and stone tools. Based on the stratigraphical evidence and the shapes of unearthed objects, the excavated remains can be divided into two phases. The early phase is represented by the House-foundation 96F1 and belongs to the Spring-and-Autumn period. The late phase embraces Ash-pit 96H1, Ditch 96G1 and stone implements,dates from about the Warring States period, and must belong to the late Liutingdong culture.
