Archaeologists carried out a survey for Hongshan culture on Tuesday in Shuangta District.

Hongshan culture is an important prehistoric archaeological culture dating back roughly 5,000 to 6,000 years. Its distribution covers three regions located in the west of Liaoning Province, the north of Hebei Province and the east of Inner Mongolia Autonomous Region. Among these, Liaoning is the core area in terms of Hongshan culture distribution and the focal region for studying this culture.
