The discoveries were made in the provinces of Shaanxi, Henan, and Hebei. The discoveries include:

* **A large-scale ancient city in Shaanxi province:** This city, dating back to the Neolithic period, is believed to have been a major trading hub for the region. The city’s layout, with its grid-like streets and large, circular buildings, suggests a sophisticated urban planning and social organization.

This site, known as the “Yangtze River Basin Neolithic Site,” is significant because it provides valuable insights into the early stages of human settlement in the region. The site’s discovery has been hailed as a major breakthrough in understanding the spread of agriculture and the development of early civilizations in China. It sheds light on the transition from nomadic hunter-gatherer societies to settled agricultural communities.
