A collection of short messages sent by the head teacher in winter vacation

L 1: Teacher, do you still remember me? That naughty and ignorant child. When you receive this message, you will think that I have come to your side again. Your teaching is the brilliant sunshine shining in my heart, which makes my youth bloom. Thank you very much. Here: I wish you a long life, happiness and success.

Math: "Success = your teaching+our efforts". You filled in half the formula for us, and we will fill in the other half for you, believe me! Happiness+happiness+longevity = my sincere blessing.

I wonder if I can help you. If not, sorry.
