Ems sends SMS appropriately.

There are two possibilities for the "appropriate investment" situation you mentioned:

First of all, the receiving post office did adopt fraudulent means to meet the time limit requirements of the State Post Bureau.

Second, since the post office covers almost all areas of China, it inevitably includes underdeveloped villages. Your mail should be sent to rural areas, because it is impossible for the post office to set up offices in every village (imagine how many villages there are in China). Therefore, rural mail (as it has been for decades) is signed by the rural postman at the next higher post office in the village, and then sent to the village because there is no computer network in the village.

(Rural postal workers are not postal workers, but they have postal subsidies. Generally, they are part-time residents' committees or villagers in the village. )

The local station 1 1 185 tells you that the three-day arrival time of EMS is irresponsible, but I think many users who don't understand postal services also have this misunderstanding, because the service commitment of three days or less is generally only for cities or individual regions (such as the Pearl River Delta). In other places, if you spend one more day in the town, you will spend one more day in the village. For example, in some areas (such as Tibet and Yunnan), there is no road in the countryside, and it takes 7- 15 days for the courier to make a round trip. Therefore, according to the actual national conditions in China, it is impossible for all regions to arrive in three days. I think this is the common sense that an ordinary consumer should have.
