On November 19th, the reporter learned from the "Expert Demonstration and Achievement Conference of Archaeological Excavation at Pingquan Dongshantou Site" held in Chengde City, Hebei Province that in the past four years, significant achievements have been made in the archaeological excavation of Pingquan Dongshantou Site, which has basically clarified the layout and structure of the site. 69 types of relics have been discovered, and more than 100 cultural relics such as pottery, stone tools, and jade have been unearthed, providing new evidence for the study of Hongshan Culture. The Dongshantou Site is located in Taitoushan Town, Pingquan City, Chengde City, Hebei Province, dating back approximately 5500 to 5300 years. Starting from 2022, a joint archaeological team consisting of Hebei Provincial Institute of Cultural Relics and Archaeology, Chengde Municipal Bureau of Cultural Relics, and Pingquan Municipal Bureau of Tourism, Culture, Radio and Television will conduct a comprehensive archaeological excavation of the site, with a total excavation area of 2400 square meters. It is understood that the site is divided into a stone mound burial area and a sacrificial area, with two layers of cultural accumulation on top and bottom. Among them, the southeastern part of the lower cultural accumulation is a rectangular stone mound burial area, and the northwestern part is suspected to be a sacrificial area; In the accumulation of upper culture, the area of the stone mound has expanded, and the structure has changed from rectangular to circular. The southeastern part of the mound is a sacrificial area. According to Hu Qiang, deputy curator of the Hebei Provincial Institute of Cultural Relics and Archaeology, some important relics have been discovered at the Dongshantou site, such as the remains of stone piled plastic earth mother, tombs composed of underground wooden cover plates, stone coffins, and wooden coffins, and remains of mountain sacrifices. In addition, the burial of pottery sculptures of men and women in the tombs of this site is the first of its kind in the archaeology of the Hongshan Culture. These new discoveries have added new content to the study of Hongshan culture and are of great significance for understanding the social complexity process of the late Hongshan culture and the formation of Chinese civilization's ritual system. ”Hu Qiang said. According to archaeological investigations, in addition to the Dongshantou site, more than 30 Hongshan Culture sites have been discovered in the Laoha River and Luan River basins in Chengde area. Zhang Wenrui, the director of the Hebei Provincial Institute of Cultural Relics and Archaeology, stated that these discoveries fill the gap in the research and distribution area of the Hongshan Culture in northeastern Hebei Province. Combined with the discovery of many Hongshan Culture sites in northwestern Hebei Province, the distribution range of the Hongshan Culture has been expanded to the entire southern and northern parts of the Yanshan Mountains and the Liaohe River Basin. The Hongshan Culture is an archaeological culture of the late Neolithic period in northern China, originating around 6500 years ago and entering the ancient civilization stage around 5800 years ago. The formation, development, transformation, and subsequent impact of the Hongshan culture are important components of the study of the origin of Chinese civilization, and provide important clues for the formation and evolution of the diverse and integrated Chinese civilization.
