There is a kind of love that can't be forgotten, and there is an unforgettable feeling, that is, the teacher's teaching. Some people say that the teacher is lighting candles, but in fact you are more like the sun that never sets in our hearts. Thank you, dear teacher.

Dear teacher, your inculcation is like spring breeze, like Seo Woo, and it will always be engraved in my heart. I sincerely wish you happiness!

The name engraved on the board may not be immortal, and the name engraved on the stone may not be immortal; Teacher, your name is engraved in our hearts.

Teacher, we will always review your encouragement, and we will not give up our success.

Three years passed quietly in the bell of class. In the past three years, a beautiful movement composed of numbers has been lingering in the classroom for a long time.
