The main function of post office is to handle and deliver letters, parcels and other postal services, but it lacks professionalism in newspaper delivery. The delivery of newspapers needs to consider the time requirements of subscribers and the particularity of delivery places, which does not match the daily workflow of post offices. The delivery of newspapers involves more manpower, time and cost. Compared with delivering letters, newspapers are bigger and need more logistics resources and manpower input. The post office believes that this delivery service is costly and does not meet the benefit considerations of its operation.
