In the Great Han Empire, there was a type of official title that could either be appointed by the Central Bureaucracy or be inherited. This official title was known as the protectorate general.
Protectorate generals could only be seen at the borders of the Great Han Empire. For the sake of managing the ethnic minorities and tribes at the borders, as well as to defend the frontier and strengthen the nation's authority, the Great Han Empire had assigned many protectorate generals at its borders.
