What is the Confucian worldview?

The world is a world with a center and a periphery, which have different levels in the political order. However, because the world is integrated geographically and politically, and the edge is an inseparable part of the "integrated" world, the frontier as the edge of the "world" is relative to the center. This complex relationship between the center and the edge is clearly defined and interrelated, which is reflected in the concept of border management, that is, on the one hand, the center should follow the edge, on the other hand, on the premise of ensuring the stability of the center, the stability and development of the frontier should be emphasized to maintain the integrity of "integration of the world".
