I received a short message this morning asking me to pick up the express somewhere. But I didn't buy anything. I'm a little worried. Do you need to call the police? What should I do?

It's best to check whether you or your friends have bought anything at this address first, and then contact the courier company to refuse or let them handle it themselves. Maybe the other party wrote the wrong address or phone number, or it may be cash on delivery. The worst result is that someone uses your information to mail prohibited items.
