The Gongjiawan site,about 1200m2, locates at Chafang township of Danfeng county. According to the stratigraphical deposits and the characteristics of the cultural relics,Gongjiawan site can be mainly divided into three phases. The first phase is Yangshao Culture. The second is early period of Longshan Culture,which is discovered in the uper reaches of Danjing River for the first time,the discovery fills an important gap in developing alignment of archaeological cultures in this region. The third belongs to the middle-late era of the Western Zhou,which is different from that of the corresponding period of Guanzhong district, while is closed to that of Chu culture of the corresponding period of Hubei Province. The discovery is important for us to explore the distribution of Chu culture and cultural rela- tion between Western Zhou and Chu at that time.
