After leaving the international mail processing center, the next stop, Shanghai International Mail Exchange Station (after transit), has been handed over to the airline for transportation.

Mail processing center refers to the production and business operation unit responsible for sorting, shipping and forwarding mail in postal communication network. The nodes that constitute the postal communication network are the sorting center and the delivery center of the mail in this postal area, and also undertake the transfer task of the mail in other postal areas. According to the number of functions, it is divided into two categories: comprehensive mail processing center and special mail processing center.

There are two types: first-level management system and second-level management system. In the former, the computer in the central control room (also known as the main control room) communicates directly with the terminal equipment of each production workshop and operation department. The latter set up sub-control rooms in each production workshop, and communicated with the computers in the main control room and other workshop sub-control rooms through computer local area network to achieve the purpose of resource sharing, information sharing and distribution.

Extended data:

All express delivery needs to go through the transfer station first, and the transfer station of the express delivery company is not necessarily in the provincial capital. Express mail is generally delivered in large quantities and the transportation route is fixed for a long time. "The setting of the route is costed, so it is relatively the most cost-saving. If a route is added in order to send a small amount of express mail, the cost will definitely increase, which is not conducive to standardized management. "

In order to implement unified management, the route of express delivery is fixed, and the express delivery company will not transport according to the distance of the location, but according to the level of the outlets. For example, it will be shipped to the highest local outlets first, and then distributed to various cities by outlets. Moreover, there is no direct network cable in many places, and there is a transit station in the middle, so the logistics information will show that you have to go to many transit stations to reach your destination.
