Where did Haicheng people move before?

Haicheng (county-level city) belongs to Anshan and has a long history. The excavation of Xiaogushan cave site proves that ancient humans thrived here as early as the Paleolithic Age 10,000 years ago. From the analysis of wooden shed tombs, it is found that in the Neolithic Age 7,000 years ago, the way of life and production of human beings has been greatly developed. Since the Qin and Han Dynasties, Liaoning Tunnel, Haicheng and other 16 states (counties) have been established in this territory.
