1: This is generally the case. The provincial capital is transferred from point to surface, and then distributed to prefecture-level cities by the provincial capital, and then transferred to various outlets in the county. Some will be transported to the provincial capital, and the local part will be put down first, depending on the actions of the provinces, and they can operate freely.

2. The function of distribution center and transfer station is generally to go to the provincial capital terminal to pull back the goods and sorted out the parts from the counties, and then wait for the county outlets to come and load them. Delivery from the county is the same process, and the head office will definitely manage its subordinate branches. Needless to say, a general prefecture-level city is in charge of all subordinate counties in this city. Not all cities and counties have branches or outlets, but it depends on whether there are people opening them. These can all be done in private.

I don't understand the operation of SF Express. Sorry, what I know is Dayun, Zaitong and so on.
