Sometimes we will try the services of different courier companies, we will choose between Fedex, DHL, UPS. However, the efficiency between them is also not stable, sometimes this one is fast, sometimes that one is fast. At the same time, we sometimes listen to the suggestions of express agencies and choose EMS, but what they say is not necessarily correct. The nasty COVID-19 epidemic has lasted for more than a year, and airlines around the world are not operating normally. So, I hope my friends will understand. It is hoped that the epidemic will end soon and the global economic order will be restored as soon as possible. At the same time, I wish my friends all safety and health.
