It's about 1260 km from Shanghai to Shantou, which is far away, but now the expressway is very developed and fast.

If the express delivery is from Shanghai to Shantou city, it usually takes 3 days, not more than 4 days.

However, any express transportation generally has no fixed route, because express transportation determines the road according to the quantity and direction of express mail, and sometimes it needs to be transported by detour.
