A series of tombs built thousands of years ago were discovered in a construction site in Zhoukou City, central China's Henan Province.
The archeological site in Xiangcheng, a county-level city, consists of 21 tombs, spanning from Warring States Period (475-221 BC) and East Han Dynasty (25-220), said Han Yanzhen, a scholar with cultural heritage institute of Zhoukou City.
Among them, 19 tombs are earth pit in shape and another two are brick-chambered tombs. Archeologists say all but five tombs were damaged by robbers. Lots of funeral paraphernalia including pottery, bronze wares and jewelry were found in the tombs. A well-preserved bronze sword was one of the rarer discoveries, said Han, who added that it was well preserved due to the local soil condition.
