1, Shushan has a diligent path, and there is no limit to learning the sea.
2, the blade is sharpened, and the plum blossoms are bitter and cold.
3, the sound of reading in the wind and rain, the sound is in the ear; Family affairs, state affairs and world affairs are all concerned.
4. The roots of talent and wisdom are still there; Lazy nature, wasted wisdom.
5, jade is not awkward; A man without learning is without skill.
