The relics are believed to date back to between the Warring States Period (475 BCE-221 BCE) and early Western Han Dynasty (206 BCE-220 CE) with the help of radiocarbon dating, Xinhua reported.
The ruins, around 150 meters long and 100 meters wide, are located on a sand dune near Dajinshan Village in the city of Shuangliao, according to the School of Archeology affiliated with the Jilin University.
Fang Qi, the archeologist who headed the excavation, said more than 60 ancient houses, four tombs and more than 300 ash pits have been discovered. And more than 2,400 pieces of relics, including pottery, bone, stone and bronze wares, were also unearthed in the 1,400-square-meter site.
Experts believe the excavation of the Dajinshan site will provide important archeological materials on the living, working conditions and social structure of ancient people in the Bronze Age in the Eastern Liaohe River basin.
Jointly launched by researchers from countries including China, France, and the United States, the ongoing excavation started in July 2018.
