The Shanxi Provincial Institute of Archaeology recently released the excavation data from the Tai'an site, located in Ruicheng county, Yuncheng, North China's Shanxi province.

According to the data, a total of three ash pits from the Longshan period (2900-2100 BC) were discovered. The unearthed pottery is mainly gray pottery, with a small amount of the pottery being gray brown and reddish brown. The existing area of the site is about 200,000 square meters and includes relics from both the Yangshao period (5000-3000 BC) and Longshan period.

The Tai'an site is located in the northeast of Tai'an village, Guwei town, Ruicheng county. It was first discovered during an archaeological survey in southern Shanxi from 1959 to 1963. In March 2020, to help construct the tourism road project in Ruicheng county, the Shanxi Provincial Institute of Archaeology conducted archaeological excavations on the Tai'an site that the road was set to pass through. As a result, three round ash pits were discovered, with various types of pottery unearthed.

According to the characteristics of the unearthed pottery, the Tai'an site can be roughly dated back to two periods, namely, H2 and H3, the early period, as well as H1, the late period. After Carbon-14 dating, the H1 period is identified as lasting from 2144 BC to 1960 BC and the H2 period from 2468 BC to 2287 BC.

In addition, archaeologists also discovered five house sites, six ash pits, and more than 20 pottery sites from the Longshan period around the excavation area. According to the investigation, the existing area of the Longshan period site is about 170,000 sq m, and the remaining area of the Yangshao period site is about 50,000 sq m.
