0?0The Book of Poetry?0?3 widely reflects the life of China's slave society and is the source of what style of poetic composition in ancient China?

The Book of Poetry is the source of China's realist poetry. The Classic of Poetry is the first collection of poems in China, which includes 311 poems of more than five hundred years from the beginning of the Western Zhou Dynasty to the middle of the Spring and Autumn Period, also known as "Poems 300". It is also known as "Three Hundred Poems". The pre-Qin period is called "Poems", or the whole number of poems is called "Three Hundred Poems". The Book of Poetry is the glorious starting point of Chinese realist literature. Because of its rich content and high achievements in thought and art, it occupies an important position in the cultural history of China and even the world. It initiated the excellent tradition of Chinese poetry and had an indelible influence on the literature of later generations. The influence of The Book of Songs has also gone beyond the borders of China to the whole world. The Chinese version of the Book of Songs was introduced to Japan, Korea, and Vietnam at an early date. From the 18th century onwards, translations into French, German, English and Russian appeared. The original main uses of the musical songs in the Shijing were, firstly, as part of various ceremonial rites, secondly, for entertainment, and thirdly, to express views on social and political issues. Later, however, the Shijing became a cultural textbook commonly used in the education of the nobility, and the study of the Shijing became a necessary cultural quality for the nobility. On the one hand, this kind of education had the function of beautifying language, especially in diplomatic occasions, it was often necessary to quote verses from the Book of Poetry to express one's own meaning in a twisted way. This is called "assigning poems to express one's will", the details of which are recorded in the Zuo Zhuan (左传). The Analects of Confucius recorded the words of Confucius, "If you don't learn Poetry, you can't speak." "Recite "Poetry" three hundred, awarded to the government, do not reach; make in the four directions, can not specialize in the right, although more also Xi thought?" It can be seen how important the study of the Book of Poetry is to the upper class and to those who are preparing to enter the upper class. On the other hand, the education of the Book of Songs also has political and moral significance. Confucius was quoted as saying in The Book of Rites and The Explanation of the Scriptures that the teaching of poetry could lead to "gentleness and generosity". In the Analects of Confucius, he also said that after learning the Poetry, one could "serve the ruler from afar and the father from near", i.e., one could learn to serve the ruler and the elders. According to the opinion of Confucius (which should also be the opinion of the general people in the upper class of the society at that time), "The 300 Poems, in a nutshell, say: Si Wu Yi". That is to say, all the works in the Book of Songs (or at least in general) were in line with the recognized moral principles of the society at that time. Otherwise, they could not have been used to "educate". Confucius said, "Music is not obscene, and mourning is not sad."

There are two points worth noting here: first, if we speculate on the views of the people of that time on the Book of Songs based on what Confucius said, the scope of what they defined as "no evil" was still quite broad. Many poems denouncing the darkness of rule and expressing the love of men and women could still be considered "innocent", i.e., legitimate expressions of feelings, as long as they did not exceed a certain limit. Secondly, nevertheless, the Book of Songs is not a mere collection of poems; it is both a cultural accumulation of the Zhou dynasty and an object of daily recitation for the aristocracy. Therefore, although it contains a number of folk songs, I am afraid that it is unlikely to contain content that positively and directly conflicts with the socially recognized political and moral principles.

The Qin dynasty once burned all Confucian texts, including the Book of Songs. However, since the Book of Poetry was easy to memorize and generally familiar to scholars, it was again circulated during the Han Dynasty. At the beginning of the Han Dynasty, there were four schools that taught the study of the Book of Poetry***: the Regulus of Qi, the Shen Pei of Lu, the Han Ying of Yan, and the Mao Heng and Mao Jang of Zhao, referred to as the Poetry of Qi, the Poetry of Lu, the Poetry of Han, and the Poetry of Mao (the first two took the name of the country, and the last two took the family name). Qi, Lu, and Han were the three families of modern scripture, an officially recognized school of thought, and Mao Poetry belonged to ancient scripture, a folk school of thought. However, after the Eastern Han Dynasty, Mao Poetry became more and more prosperous and was officially recognized; the first three families gradually declined, and in the Southern Song Dynasty, it was completely lost. The Poetry Scripture we see today is a copy of the Mao school of poetry.

Also, "Poetry 300" is one of the main textbooks in China from "Spring and Autumn" to "Qing Dynasty". I hope my answer is helpful to you(*^__^*)
