The Northeast (Manchuria) and the Nordic countries are the latitude-50 mirrors of their civilizations. Long winters, sparse old populations, recent waves of industrial migration, deep timber forests, ice-class harbours. Both regions punched far above their weight in industrial output for a brief 20th-century period (Northeast under Mao; Sweden / Finland under social-democracy) and both are now reckoning with depopulation, ageing, and what to do with the company towns the old factories built.东北与北欧，是两种文明在北纬五十度的镜像。漫长的冬天、稀薄而年老的人口、近代的工业移民潮、深邃的木材森林、冰区港口。两地在 20 世纪短暂的一段时间里产能远超体量（毛时代的东北；社民主义下的瑞典、芬兰），如今同样在面对人口萎缩、老龄化，以及「老工厂留下的企业镇该如何处理」。
