Poems that can be used as mottos are as follows:

1. Learn from the world, learn from it, and accumulate it.

explanation:

It comes from Xu Zhixing's famous saying about reading composition: "Learn from the book, take it from it, accumulate it, and make it thin." According to the author's understanding, "about taking" here means not only taking less, but also taking carefully and carefully, while taking the essence and discarding the dross. The so-called "take" is the recognition and acceptance of what is said in the book, what is said, and what is expressed. "Take" is not expensive, but expensive, and should be "a little less wins more".

Appreciation:

If reading extensively is important, it is more important to be careful and careful. Some books, even excellent ones, are often not full of words and truth, but are full of flaws, refined and coarse. Therefore, we can't take everything into consideration without analyzing it. We must seriously think about it, distinguish between the good and the bad, get rid of the rough and get the best, and discard the false and keep the true.

2. Don't play thousands of songs before you know the sound, but watch thousands of swords before you know the device.

explanation:

You can't understand music until you practice 1 pieces of music, and you can't know how to identify a sword until you observe 1 swords.

Appreciation:

Although the original intention of this sentence is to explain the method of literary appreciation, the connotation it conveys comes down in one continuous line with the traditional culture of self-cultivation: "Reading a hundred times, its meaning is self-evident", "Reading thousands of books, writing like a god", "Rome was not built in a day" and "Reading thousands of books, traveling on Wan Li Road"

3.

Explanation:

If you don't climb the mountain, you won't know how high the sky is; If you don't face a deep stream, you don't know how thick the land is.

Appreciation:

During the Warring States period, the slavery system further collapsed, the feudal system gradually formed, and history experienced epoch-making changes. Many thinkers expressed their opinions on the social changes at that time from different standpoints and angles, and gradually formed different factions such as Mohism, Confucianism, Taoism and Legalism, which were called "hundred schools of thought" in history.
