Did you send a blessing message to the teacher?

Of course it doesn't matter, silly boy. It is not surprising that many people are polite. Of course, if you know a teacher, such as your teacher and counselor, it will be a bit abrupt if you have never met or only attended a lecture once.

However, in the Spring Festival and other festivals, no one will pay attention to many of your news at all.

Not a bad thing.

don't worry
