Is it appropriate for graduate students to visit their tutors and send WeChat?

When you visit your tutor, you must tell him in advance. You can send a message on WeChat or make a phone call.

Tutors should be students who can do things and talk less, that is, students who can do everything. So don't talk big when you meet your tutor for the first time. This kind of student tutor is probably annoying. You'd better prepare some professional questions to show your ability to your tutor.
