1. If you are always proud of what you have gained when doing things, then you will not be able to do anything well. It can be said that "humility makes people progress, and pride makes people fall behind."

2. Falling red is not a heartless thing, it turns into spring mud to protect flowers.

See this sentence. Respect for the teacher arose spontaneously in my heart. Teachers are hard-working gardeners, nurturing the flowers of the motherland with their hard work and sweat, without asking for anything in return. They always devote themselves in obscurity like fallen leaves. Turn into spring mud to nourish the earth. I love my teacher because he has a shining heart of gold. Dear teacher, I want to say to you: Thank you for your hard work.
