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.

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

When three people are walking together, I must be my teacher.

Knowledge is power.

Where there is a will, there is a way.

Nothing is difficult in the world, only those who are willing can do it.

As long as you work hard enough, an iron pestle can be ground into a needle.
