19世纪60年代以后,清政府对东北地区由封禁政策转向部分开禁进而全面开放,关内移民大量涌入东北地区,其中一部分进入到三江区域。移民的到来,促进了该地区经济的发展,推动了工商业的兴起,加速了城镇的繁荣与发展。 After the 1860s, the Qing government opened its door to partial opening up of the banning policy in the northeast region and opened up to the outside world in an all-round way. A large number of immigrants from the territory of Guan have flooded into the northeast region, and some of them have entered the Sanjiang area. The arrival of immigrants has promoted the economic development in the region, promoted the rise of business and industry and accelerated the prosperity and development of cities and towns.
