Books:

Books are the ladder of human progress.

Books are like friends and must be chosen carefully.

Diligence:

There is a road to 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.

Genius is 99% perspiration and 1% inspiration
