How to send a text message when you invite a teacher to dinner?

Inviting teachers to dinner is also a science. First of all, what is the purpose of inviting the teacher to dinner? If it's, uh, work, I'd like to meet the teacher. Then you can say, please let the teacher use this, and then say, catch up with the old days and meet this again. In this case, you can just say that you said, well, you have graduated for many years, and then you want to invite the teacher out, and then Xu just. If you are still his student. If you think it is not easy for the teacher to teach you, you can just talk to him face to face, or you don't have to send a text message. I think it's better to talk to him in person than to send a text message. If you can't see her like a worker, call and send a text message, and then if you can see him, you'd better tell him in person. If you are still his student, you can say, Oh, I think the teacher is working hard, and then you can say that you want to play it with some classmates. Oh, one is to invite teachers to get together and then set up a banquet. If you want Teacher Tu to be nice to you for other purposes, I suggest not to do so, because you are still a student. If you are a student, I don't think you should learn these extra things.
