Han Yu
Reading costs nothing, but benefits ten thousand times. Read ancient books in front of the window and look for the meaning of books under the lamp. The poor are rich because of books, and the rich are expensive because of books.
This poem means that you can become knowledgeable without spending money on reading; Study hard; The poor become rich with knowledge after reading, and the rich become noble with books after reading.

[Song] Liu Guo
Mechanics is like cultivated land,
Diligence knows.
But writing more books,
Will be years old.
The meaning of this poem is to study hard, like a farmer plowing the land, being diligent and lazy is well aware; If you read more books and increase your knowledge, you will have a bumper harvest in agriculture. It also reflects a little effort and a little gain.
Diligence and diligence spoil the mind. -Hua
