From the price point of view, everything else is similar to SF. If it's faster, SF sends it twice a day, and the speed of air parts is faster. Other express delivery is similar, so it is necessary to compare the services. The service of express delivery has little to do with the brand, mainly depending on the quality of personnel in Yichun outlets. From my personal experience, these big brands have a big temper, but small brands are more polite, and the quality of couriers is acceptable. If you don't send something once, send it again instead of letting others sign for it.
