Why is Shenyang EMS Express so slow?

Brother, if this phone really doesn't work, you have to go out in person. The ems in our hometown is also very rubbish. I bought two things on Taobao. Shentong's arrived early. It was transported by land. Ems has been in my hometown city for 4 days. Not only did you not send it, but you also signed for it for me. Now I don't know where everything has gone. Headache. Garbage in EMS slow delivery
