How about using spring rain as a metaphor for teachers?

Spring rain, like spun silk, is a frivolous metaphor for human speech, probably a compliment to gentleness and kindness.

Spring rain is like a teacher, praising selfless dedication.

Compare a teacher to a gardener as a spring rain, and cultivate peaches and plums to bloom all over the world. Moistening things quietly, teachers are a lofty cause in the world. The teacher gave us ideal sunshine and wisdom sunshine. The teacher guided us to the path of sunny life. Teachers expect us to be the sun in the new century. The teacher's words moisten my heart like spring rain. The teacher watered our growth with the rain of knowledge. Gentle spring rain is the teacher's love for us. The teacher's words and deeds are like spring rain. The teacher is willing to be a green leaf and hold us up as red flowers. The teacher is a green leaf, willing to contribute silently. The green leaves symbolize that teachers are always young. When we bloom like flowers, we will never forget the kindness of green leaves. Teachers are like trees, with blue sky overhead and feet on the earth, silently making contributions to society.
