The Significance of Frontier Governance in Tang and Yuan Dynasties

The characteristics of ancient frontier governance are that a large number of troops are stationed in frontier areas and in various places in the form of health stations. The sergeant in the health care center has a military record and is allowed to bring his family's children. This sergeant has been a military family for generations. Most of the sergeants took part in the reclamation, and a few were stationed. When there was a conquest, the general was ordered to lead the troops at the designated guard station, and the troops returned to their original places after the incident. In the southern border provinces, counties and health centers are both external and internal, while governance complements each other. Health centers located in areas without prefectures and counties are under the jurisdiction of civilian families and civil affairs departments.

The significance of frontier governance lies in that it shows that the world is a complete whole, and the world is unified rather than divided first. Although there are levels and levels in the world, it is a difference order in a unity. The unification of the world is inevitable, and division is against the sky. Therefore, the frontier belongs to the whole, the frontier cannot be separated from the center, and the frontier cannot be separated. This basic understanding of the concepts of territory and frontier has become the theoretical basis of China's thought of great unification, which has a far-reaching impact on history and is also the theoretical basis of inseparable frontier.
