Xiao Pan, before entering the building, you need to show your ID. That's a basic rule.

Okay. I have a student ID card. Can I use that?

Yes. Show it to the security guard at the entrance, and they will register your information.

I saw some people writing their names. Is that for registration?

That's right. Visitors need to write their name, the time, and the purpose of their visit.

If a visitor comes to see us, what should we do?

First, verify their ID, then call the relevant colleague, and finally escort the visitor inside.

I understand. We need to check carefully and also be polite.
