I am a student in this school ~EMS guarantees that I can arrive and send it to the school to be received by the reception office. Then the other person's name appears on the blackboard at the door. I can get it with my ID card when I see it. EMS may be more expensive, but it will be slower to send an ordinary parcel to the post office. But I don't know about other express delivery, because the school is remote and many express delivery don't pass through this small city.
