According to the WeChat official account of the National Cutural Heritage Administration, on September 13, the National Cutural Heritage Administration held a working meeting on the important progress of the "Archaeological China" major project in Beijing, which reported three recent archaeological developments, namely, the Huangchadun site in Quzhou, Zhejiang, the Caoyang port site in Xinghua, Jiangsu, and the Baliqiao site in Fangcheng, Henan. This conference focuses on important archaeological discoveries of prehistoric and Xia cultures. The Huangchao Dun Site is a settlement site from the early to mid Neolithic period, dating back to about 9300-8000 years ago. Important relics such as terraces, moats, and rice fields have been discovered, revealing the rice farming settlements from the Shangshan Culture to the Kuahuqiao Culture period. It is a vivid microcosm of the early rice farming society in the lower reaches of the Yangtze River. The Caoyan Port site dates back to about 7200-6900 years ago and is the earliest known Neolithic site in the eastern part of the Jianghuai region. The special low altitude wetland burial environment has allowed a large number of organic matter relics to be well preserved. More than 2800 relics such as pottery, bones, stones, wood, jade, and clams have been discovered, with a novel cultural appearance and rich connotations, and distinct regional characteristics, filling the archaeological gap of the Neolithic period in the Jianghuai region. The Baliqiao site is the largest and highest level Erlitou cultural settlement discovered in the southern Henan region. Multiple gully like relics have been identified, dividing the southern part of the site into five areas. Important relics such as large rammed earth foundations and sacrificial pits have been discovered, and pottery, jade, and green pine stone tools have been unearthed. This provides new clues for exploring the settlement morphology and social structure of local cities in the Xia culture, and is an important breakthrough in the archaeological work of the Xia culture.
