The problem of express delivery

Now a lot of courier is to go by air, need a site a site of the shipment, each site also need to go back and forth to the point of goods, inspection, scanning and so on. For example, if you are in Shenyang, the goods to the airport (are the edge of the city, very far) after the distribution of small sites, small sites may be very late to go to the airport to pick up the goods (every day there is a fixed time), and then the next morning (usually 6:00 a.m.) scanning, sorting, and then distributed to the streets of the school, and so on. Now the courier riding an electric car more (because if you drive, the gas money is not reported), a limited number of shipments, so there may be a long delay, so even if your goods to your city may be delayed for a day, of course, a good courier (such as SF) is more demanding, the day of the goods must be delivered sometime on the same day, or accordingly penalized courier personnel, which will be a lot faster. But usually 3-5 days also arrived.
