Chinese archaeologists recently discovered some sites containing relics dating back to the Neolithic Age near Changchun, capital of Northeast China's Jilin province.

Archaeologists began to excavated the sites on Wutai Mountain in June. Pits, houses and tombs have been discovered.

Wang Yixue, leader of the archaeological team, said these are the first complete relics of Neolithic houses and tombs that have been found in the region.

More than 200 ceramic, jade and bone artifacts, and tens of thousands of ceramic pieces have been unearthed. A complete goat skeleton, believed to be a sacrifice, was found in a pit.

Discoveries at the sites will enrich knowledge of the history of Songhuajiang River and basin regions, said Duan Tianjing from Jilin University.
