What are the first-line and second-line brands of international express delivery?

The best is downwind express, but as far as EMS is concerned, these two are first-class, and the second-rate is four-way. The order of four links and one arrival is 1 Tong Yuan 2 Shentong 3 Zhongtong 4 Dayun 5 Huitong. The rest of Guo Tong, Quanfeng and Long Bang are third-rate almost every day. A courier company can't be the same in every branch.
