Write a short message format to the math teacher.

Teacher, you have worked hard. You gave us a clever mind. From the most basic addition, subtraction, multiplication and division to complex formulas, you have benefited me a lot. Although some people don't understand, you patiently taught us to take full responsibility for our own life wisdom. Your teaching has given us wings to fly to our destination and lit the lamp of hope. You gave us a bright future, but you stayed where you were and taught other students and teachers. I want to tell you sincerely, teacher, that you have worked hard!

Music teacher:

Hello, teacher, you teach us with your most beautiful voice, and let us imitate your voice with the sound of nature. Teacher, you have worked too hard, and your face is haggard. You asked us to sing loudly, but your voice was hoarse for us. After this session, will you teach the next session? Teacher, I heard your firm heart and answered: As long as you learn my teaching, it will not be in vain! Teacher, please relax yourself and give yourself a relaxed tomorrow! Teacher, you have worked hard!
