This is the remains of a tomb dating to the Neolithic. The extant structure consists of a large stone slab supported on several standing stone uprights. Of the same period, remains of stone buildings and impliments have been found in Haicheng's Shimu, Pailou, Datun, Chagou and Tengao, etc. Other ancient relics have been found in Xiaogushan near Haicheng and are Paleoanthropelogical Relics of at least 20,000 years ago. These demonstrate that civilisation developed in the area around Anshan contemporary with the ancient civilisations of the Central Plains of China. These stones stand 2.8 metres high like a lesser Stonehenge.
