Flowers will bloom again, and people will never be young again.

There are roads in the mountain of books, and diligence is the path, and there is no limit to the sea of ??learning, and hard work is the boat.

If a young man does not work hard, the old man will be miserable.

Black-haired people don’t know how to study diligently early, and white-haired people regret studying late.

The book has its own golden house, and the book has its own beauty like jade.

The fragrance of plum blossoms comes from the bitter cold, and the edge of the sword comes from sharpening.
