Dawenkou Culture is a Neolithic Age culture, named after the Dawenkou site located in Tai'an City, Shandong Province. In 1959, hundreds of tombs were excavated at the Dawenkou and Baotou sites at the junction of Tai'an and Ningyang Counties in Shandong Province (now Daiyue District and Ningyang County, Tai'an City, Shandong Province), and a large number of unique cultural relics were unearthed. . Later, sites and tombs of the same type of culture were continuously discovered in the vast areas of Shandong and northern Jiangsu. This was the Dawenkou Culture. The distribution area of ??Dawenkou culture extends from the coast of the Yellow Sea in the east, to the eastern part of the Luxi Plain in the west, to the south bank of the Bohai Sea in the north, and to the Huaibei area of ??Jiangsu in the south. It is basically located in the Shaohao culture area recorded in ancient books and is the source of Longshan culture. In addition, sites of this cultural type have also been found in Henan and northern Anhui. According to radiocarbon dating and correction data, the Dawenkou Culture dates from about 6,500 to 4,500 years ago and lasted about 2,000 years. According to the stratigraphic stacking relationship and relic characteristics, it can be divided into three phases: early, middle and late.
