Archaeologists announced Wednesday neolithic ruins dating back 4,500 to 5,000 years had been found in southwest China's Sichuan Province.
The ruins was found on Ling Mountain in the ancient city of Langzhong last July, when villagers were building a reservoir, said Sun Zhibin, from the Sichuan Provincial Cultural Relics and Archaeology Research Institute.
A team led by Sun excavated the ruins from September 2016 to January 2017.
A total of 108 items were found at the ruins, including porcelain pots and plates, and stone tools, such as axes and spears.
"The discovery has provided new material for the research on cultural blending in the Sichuan Basin and its surrounding culture," he said.
The discovery, the first ruins dating back to the late neolithic period near the middle reaches of Jialing River, has put back human activity at Langzhong from 3,000 years ago to 4,500 to 5,000 years ago, said Sun.
