Sign the teacher's name through the Spring Festival SMS.

Yes, you think that sending blessings to the class teacher is enough to prove that you are a polite student. As for the signature, write it! Poor study doesn't mean that teachers will hate you. In every teacher's mind, students can have bad grades, but their personalities must be good. So your teacher won't hate you, but will be happy with your message. After all, few students think of their teachers after the holidays.
