Send a blessing message to the teacher on Teacher's Day. When is it usually written?

Time should not be too early or too late to affect rest. I think noon or evening is fine, or before class in the morning. If you are a close teacher, such as a class teacher, texting doesn't need to be too formal. If you wish, write student xxx at the end. If you formally imitate the format of this letter,

Teacher xx:

Words of blessing

Your student

xxx
