自从十余万年前现代人类祖先走出非洲,人类已遍布包括南极洲在内的所有陆地。今天,我们能够幸福地生活、工作在黑龙江省这块黑色的沃土之上,这要感念我们中华民族的祖先。他们在历史洪荒之中,克服后工业时代的人们无法想象的艰难困苦,筚路蓝缕,开辟、建设、保卫了我们美好神圣? Since the human ancestors came out of Africa more than 100,000 years ago, mankind has covered all the land including Antarctica. Today, we can live happily and work above this black fertile land in Heilongjiang Province, which is to cherish the ancestors of our Chinese nation. In the prehistoric history of history, they overcome the hardships and unimaginable hardships that people in the post-industrial age were unraveling and opening up, building and defending our beautiful and sacred places.
