On March 31, the final results of the top ten new archaeological discoveries in the country in 2021 were officially announced.

  Jijiaocheng Neolithic Site is located in Jijiaocheng Village, Chennan Town, Li County, Changde City, Hunan Province. It is one of the four known prehistoric city sites in Hunan, and it is the central settlement of the Liyang Plain in the late Neolithic Age.

  The Huanhao settlement evolved from the Youziling culture period to a large-scale city site in the Qujialing culture and Shijiahe culture periods, which is a microcosm of the prehistoric civilization process in the middle reaches of the Yangtze River.

The settlement structure of the triple ring moat was discovered for the first time in the Yangtze River Basin, which is of great value to the study of prehistoric settlement patterns.

  The discovery of triple ring trenches, large wooden buildings, massive rice husks, and paddy fields reconstructs the complete process of rice farming and social evolution in this region.

The excavation of the Jijiaocheng site provides important data for the study of the origin of Chinese civilization and the formation of early states.
