There will be times when the wind blows and the waves break, and the cloud sails are hung directly to help the sea.
The edge of a sword comes from sharpening, and the fragrance of plum blossoms comes from the bitter cold.
If you don’t fly, you will soar into the sky; if you don’t sing, you will become a blockbuster.
The sea is wide enough for fish to leap, and the sky is high enough for birds to fly.
Time flies like an arrow, and the sun and moon fly like a shuttle.
Don’t wait any longer, your young head will turn gray and you will be so sad!
With perseverance, gold and stone can be carved.
Young people work hard all their lives, and don’t waste time and effort.
Learn and then learn.
Career is accomplished by hard work, wasteful by play, accomplished by thinking, destroyed by casualness.
Write a paragraph from "The Book of Rites and the Book of Learning":
Although there are fine delicacies that cannot be eaten, one does not know its purpose; although one has the best knowledge, one does not know its goodness. This is why after learning, one realizes one’s shortcomings, and after teaching, one realizes one’s difficulties. If you know your shortcomings, you can then reflect on yourself; if you know your difficulties, you can then improve yourself. Therefore, it is said: "Teaching complements each other."
It means that students are encouraged to study hard, teachers strive for excellence, and teaching and learning complement each other (learn from each other's strengths and complement each other's weaknesses).
