The Haihunhou tomb, which dates back to the Western Han Dynasty (206 BC-24 AD), covers roughly 40,000 square meters and contains eight small tombs and a burial site for chariot horses. The best-preserved tomb of its age found in China, it is thought to belong to Liu He, the grandson of Emperor Wu. Archeologists have determined the smaller No. 5 tomb belonged to Liu Chongguo, a son of Liu He. [Photo provided to China News Service]
