Beijing: A tomb dating back to 475-221 B.C. has been unearthed in northeast China. It lies about five meters underground and covers an area of 72 sq. meters in Dongdazhangzi village of Liaoning province.

The tomb dates back to the Warring States era, a website quoted Guo Dashun of the Liaoning Institute of Archaeology as saying.

It is the largest tomb from the period ever excavated north of the Great Wall, making it of great academic value, said Guo.

It is extremely rare to find such a large number of tombs in that region. The discovery is expected to break the traditional views on ancient civilizations in northeast China.
