Shang Shu Yu Gong is an important historical material to study the history of the pre-Qin Dynasty.From the surface,Yu Gong is a natural geographical literature, but it contains the political concept of great unification, at the economic level, political level of Kyushu relations and cultural level of five costumes system and other measures, these all reflect its idea of maintaining unity, so it is a political geographical literature.In this article, dividing the state-fixed taxes accelerated the political construction of the national unification, and the five costumes system laid the cultural foundation of the Yellow River basin for the realization of the true unification.Therefore, it is of great academic value and practical significance to interpret the text of Yu Gong from the perspective of the mainstream literature of the pre-Qin Dynasty and pay attention to the ancient national political concepts reflected by it.
