CHANGSHA, March 25 (Xinhua) -- A dozen stone weapons have been unearthed from a site dating back between 3,800 to 4,200 years in central China's Hunan Province, said the provincial cultural relics and archaeology research institute.
The Sunjiagang site, located in the northwest of Dongting Lake Plain, dates back to the late Neolithic Age to the early Xia Dynasty (around 2070-1600 BC).
The stone weapons found in the Sunjiagang site in Lixian County include spears and arrows. These relics indicate that the relationship between different communities in this area might have been relatively tense, and violent conflicts or wars occurred, said Zhao Yafeng, associate researcher with the institute.
Recent archaeological excavations also revealed a new form of residence at the Sunjiagang site, which is a simpler form of residential architecture.
The archaeological excavation and research at the Sunjiagang site has greatly enriched the understanding of the prehistoric culture of the Liyang Plain and Dongting Lake area, and provides new archaeological data for understanding the social life in the whole Dongting Lake area from the late Neolithic Age to the early Xia Dynasty, according to Zhao. ■
