Harbin is a city with a long history and no city wall. In the late Paleolithic era around 22,000 years ago, Harbin’s ancestors labored and lived before entering into the Neolithic Age 5,000 years ago and finally the late Yinshang Period (the Bronze Age) about 3,000 years ago. The city is the birthplace of both the Jin and Qing dynasties and in 1115 AD, the Jin Dynasty established its capital in Harbin’s present-day Acheng district.
