据《魏书》记载,由鲜卑族人创立的北魏王朝,他们的祖先住在北方的一个山洞里,但确切的位置书里并没有记载。因此,北魏的祖先究竟住在哪里,成了千古之谜。长期以来,相关的考古工作者多次考察,未有所获。19世纪后期,先后有日本、加拿大、俄国等国的考古人员进行过探险性的寻查,也是无果而终。到了20世纪80年代初,终于揭开了这层神秘的面纱:它就在内蒙古自治区鄂伦春族自治旗境内一个叫嘎仙洞的洞穴里。 According to Wei Shu, the Northern Wei dynasty founded by Xianbei people lived in a cave in the north, but the exact location did not contain any records. Therefore, the ancestors of the Northern Wei actually lived where, has become a mystery over the ages. For a long time, the related archaeological workers visited many times and did not get any. In the late 19th century, archeologists from Japan, Canada, Russia and other countries conducted expeditionary explorations, which were fruitless. By the early 1980s, this mysterious veil was finally unveiled: it was located in a cave called Gaxian Cave in the Oroqen Autonomous Banner of Inner Mongolia Autonomous Region.
