At different levels, the administrative level of provincial highway directors is deputy hall (bureau) level, and the administrative level of provincial transportation department inspectors is main hall (bureau) level.
The Provincial Highway Bureau is a provincial-level professional highway management organization led by the Provincial Communications Department, responsible for the planning, construction, maintenance, road administration and toll road management of the province's highways, and established as a deputy hall (bureau) level institution.
The administrative level of the provincial highway director is half a level lower than that of the inspector of the Provincial Department of Transportation. However, the provincial highway director is a leadership position and has real power in his hand. Although the inspector's administrative level is the main hall level (bureau level), he has no power in the hands of non-leadership positions and is basically an idle person.
