The ideological content of "The Book of Songs" mainly includes: poems against exploitation and oppression, poems reflecting the pain of corvee military service, poems reflecting love and marriage issues, poems reflecting working life and patriotism, and political satire. , sacrificial poems and banquet poems, etc., there are almost no poems to encourage learning. The following sentences have some meaning for people to learn from:

The stones from other mountains can attack jade. ("The Book of Songs·Xiaoya·Crane")

There is no beginning for the extravagant, and there is an end for the weak. ("The Book of Songs Daya·Dang")

The high mountains stand still and the scenery stops. "The Book of Songs·Xiaoya·Futianzhishi·Chejia"

Many people in later generations spoke highly of the "Book of Songs". Now let me quote Confucius and Mencius.

Confucius: Regarding the ideological content of the Book of Songs, he said, "Three hundred poems can be summed up in one sentence, and the thoughts are innocent." As for its characteristics, it is "gentle and honest, and poetic education" (that is, it is believed that the Book of Songs can clarify people's soul after reading it, and it is the best way to use it as a tool for education). Confucius even said, "If you don't learn poetry, you won't be able to express it." This shows the profound influence of the Book of Songs on ancient Chinese literature. The function of poetry: "Young man, why don't you learn from your husband's poetry? Poetry can inspire, observe, group, and complain. It can serve your father when you are near, serve your king when you are far away, and know more about the names of birds, beasts, and grass."

< p> Mencius: Mencius said about poetry, "Those who speak poetry do not harm their words with questions, do not harm their aspirations with their words, and use their thoughts to go against their aspirations. This is what they gain." "If you praise his poems and read his books, you don't know what he is like "This is how we talk about the world."
