Ordinary life, hard life, silent dedication of knowledge, you are the messenger of civilization, you are a diligent gardener, thank you sincerely, and wish you health and happiness.

The teacher's kindness is so heavy that students dare not forget it. I wish you good health, all the best, and a full garden of peaches and plums during the holidays. My respected teacher, my success is due to your support, saying "thank you" in a thousand words.
