Tanheli Site is located on the platform where Zhaizi Village, Huangcai Town, Ningxiang County, Changsha City, Hunan Province meets the stream and the backwater. It is the most famous bronze ware land in the south. The site dates from Shang Dynasty to Western Zhou Dynasty. Ningxiang is located in the south of the Yangtze River, but a large number of precious bronzes have been unearthed, including the largest square statue of Siyang in China, the largest bronze cymbal and the largest bronze vase.
The existing main part of Tanheli site is a fan-shaped area at the intersection of the north bank of Huangcai River and Tuduanxi River. The southwest and northeast of the city wall are close to the banks of the two rivers respectively. The preserved area in the city is about 23,000 square meters, the newly discovered protected area outside the city is 2 1 10,000 square meters, and the construction control zone is more than 400,000 square meters. 1963 was confirmed as the site of the Western Zhou Dynasty. Small-scale trial excavations were carried out in 1973 and 200 1 year respectively, and large-scale excavations were carried out from 2003 to 2004, with an excavation area of more than 2,000 square meters. Large-scale building sites and city wall sites in the early Western Zhou Dynasty were excavated, and seven tombs of Western Zhou nobles were cleared up. At present, more than 2,000 cultural relics have been unearthed in this area, including the "Four Sheep Fangzun", one of the "Top Ten National Treasures".
On the whole, the types and styles of bronzes unearthed from tombs are similar to those collected from the city site of Tanheli and those unearthed in this area in the past, and the types of jades are also the same as those collected from the site of Tanheli and the jades hidden in the nearby unearthed Gege and Yunbo. It can be determined that the tombs and city sites belong to the same culture as the bronzes unearthed in the surrounding areas. The excavation of Tanheli site has high academic value. It fills the gap of archaeological culture in the Xiangjiang River basin in the Western Zhou Dynasty, finds the cultural carrier of "Ningxiang Bronze Group" which has long troubled the academic community, and proves that Huangcai area in Ningxiang was once the political and cultural center of Hunan and its surrounding areas at the end of Shang Dynasty and the beginning of Zhou Dynasty, providing indispensable and important materials for the study of major topics such as the process of ancient civilization in China and the formation of Chinese national culture. In April 2005, National Cultural Heritage Administration was announced as one of the top ten new archaeological discoveries in China in 2004.
In May 2006, Tanheli site was approved by the State Council to be included in the sixth batch of national key cultural relics protection units.
