in terms of external packaging, SF will design an obvious LOGO from the icon and print the corresponding text logo on the top left of the box.

if a fresh word is affixed to the express box of SF Express, it proves that the contents of the express delivery are products such as fresh fruit, which is guaranteed by the time limit. This kind of express delivery should be given priority. Of course, under normal circumstances, the freight price of fresh food is higher, but the time limit is faster, just to ensure that it can be delivered to the courier in a short time, and priority will be given to delivery.
