It was learned from the Jiangsu Provincial Institute of Cultural Relics and Archaeology that at the "Expert Guidance Meeting on the Archaeological Site of the Baojia Site in Liyang" held by the Institute on the afternoon of 16th, experts agreed that the Baojia Site in Liyang, Changzhou, Jiangsu, is about 8100 years old, the earliest prehistoric site around the Taihu Lake Lake, and has the basic conditions for naming a new archaeological culture. In 2022, the Baojia Site was discovered during the evaluation of cultural relics resources in Liyang High tech Zone. In 2023, the archaeological work of the site will be included in the research project of the development process of prehistoric culture in the western part of the Taihu Lake Lake, which is part of the Jiangsu Regional Civilization Exploration Project. From 2023 to 2025, with the approval of the National Cutural Heritage Administration, the Nanjing Museum and the Jiangsu Provincial Institute of Cultural Relics and Archaeology have made important achievements after three years of archaeological excavation. The current excavation area is concentrated on the eastern edge of the site, forming a trumpet shaped estuary that gradually widens towards the east and connects with the surrounding waters. The estuary is filled with lake sediment up to 2.5 meters deep, containing a large amount of organic matter and human activity remains. More than 200 ash pits were cleared on the eastern terrace of the site. Hu Yingfang, the archaeological leader of the Baojia Site and deputy research curator of the Jiangsu Provincial Institute of Cultural Relics and Archaeology, introduced that the accumulation of lacustrine silt at a depth of 5 to 6 meters from the surface in the eastern estuary of the site is the most important harvest of this time. After careful cleaning, artificial remains such as pottery, stone tools, bone tools, wood tools, jade artifacts, as well as a large number of plant and animal remains were discovered. Hu Yingfang said that pottery has various shapes and structures, including pots, jars, basins, bowls, plates, jars, cups, and lids. The site has been in a state of saturation for a long time, and rare organic cultural relics such as wooden building components with mortise and tenon joints, mats woven from bamboo and reed plants, and ropes woven from hemp or grass (some grass ropes show knot marks) have been preserved. At the same time, plant archaeology has discovered charred rice and a large number of aquatic plants such as water chestnuts and water chestnuts. This indicates that domesticated rice had already appeared at that time, but in small quantities, and gathering and hunting were still the main sources of food for our ancestors. Archaeological discoveries of mammals such as deer, dogs, pigs, sacred water cows, raccoons, Eurasian otters, small spirit cats, and rabbits; Ducks, ring necked pheasants and other bird species; Fish such as carp, green carp, grass carp, etc; Turtles, crocodiles and other reptiles; And a large number of aquatic mollusks such as clams, clams, snails, and shells. According to the results of 24 carbon-14 dating, the age of the Baojia site is 8100-7500 years ago. Wang Wei, a member of the Chinese Academy of Social Sciences, stated that the Baojia site is located at a critical juncture in the origin of Chinese civilization. The site has discovered the earliest colored pottery, representative pottery such as ox nose ear pottery jars, and flowing pottery jars in Jiangsu Province. Research on artifacts shows that the Baojia site is closely related to the Shangshan site and the Cross Lake Bridge site in Zhejiang Province, but it has an independent cultural identity, providing key empirical evidence for the study of the origin of the Yangtze River civilization. At the expert guidance meeting, 10 experts from Chinese Academy of Social Sciences, Nanjing University, Zhejiang University, Renmin University of China and other universities and scientific research institutions reached a consensus: Baojia Site is the earliest prehistoric site in the area around the Taihu Lake Lake at present, with distinctive cultural characteristics of its own, and there are certain similarities and significant differences with contemporary sites in the surrounding areas in terms of cultural outlook and cultural connotation, breaking the existing framework of "Majiabang (Luotuodun) - Songze - Liangzhu" archaeological cultural pedigree, and filling the key gap in the cultural sequence of the Neolithic Age in the region.
