Why is the postal service surprisingly slow among many couriers?

Among many express delivery, the postal service is surprisingly slow. There are two main reasons. First, postal services are mainly postal services, supplemented by automobile transportation, which are distributed all over the country and divided into sea transportation and land transportation. In terms of shipping, airmail is very strict, and everything should be carefully checked, such as some contraband, so you must not board the plane, so it takes a lot of time here. Land transportation, in addition to checking contraband, also includes air transportation. Moreover, it does not support the whole road transportation, which requires multiple places to turn around and wastes a lot of time.

Postal express can also be transferred to the post sub-office for delivery. However, post sub-offices are not bound by postal express delivery. Employees will have lunch breaks, weekends, holidays and other breaks. At this time, the object will be stopped at the post office and can only be delivered on weekdays.

The leaders of the post sub-bureau are also extremely strict with the objects to be inspected, and the subordinate staff are also rigid in dealing with problems. If contraband is found in the same batch of goods, even the goods that have been transported away will be shipped back and will not be distributed until all the goods are processed.
