青海地区人类活动虽然较晚，但其原始文学、三代文学却基本上与甘肃地区同步，从对东周以前和春秋战国时期青海的民族文化发展情况的考察来看，都证实了这一点。因此，一个地区、一个民族的进步与否，除自然地理原因外，自身的进取和接受统一国家的管理起着决定的作用。 Although the human activities in Qinghai are relatively late, the primitive literature and the three generations of literature basically synchronize with Gansu. This is confirmed by the investigation of the development of the national culture in Qinghai before the Eastern Zhou Dynasty and the Spring and Autumn Period and the Warring States Periods. Therefore, the progress of a region or a nation, except for its natural and geographical reasons, plays a decisive role in its own progress and in its acceptance of the administration of a unified nation.
