1. Originality: Pre-Qin literature is the first glorious page in the history of China literature. Literature came into being with the daily life of people in primitive society, such as labor, sacrifice and marriage, and developed with the development of society. In the Zhou dynasty, it became a grand view. There are all kinds of literary forms, such as poetry, prose and ci fu, and there are obvious differences among historical prose, various schools of thought prose and applied prose. Second, comprehensiveness: in the pre-Qin era, there was no distinction between literature, history and philosophy, and poetry, music and dance were integrated. Literature refers to all disciplines including politics, philosophy, history and literature. Advanced Analects of Confucius says that Confucius disciples Zi You and Xia Zi are good at literature, and "literature" generally refers to ancient documents. Third, practicality: during the Spring and Autumn Period and the Warring States Period, the society was in great turmoil, great change and great reorganization, and literature was generally practical, or it was issued for specific social problems, such as the folk song "Hungry people sing their food, laborers sing their things" in the Book of Songs; Or sum up historical experience and lessons, judge the merits of historical figures, and provide reference for the real society, such as judging the right and wrong in historical prose and judging suspects; Or reveal and solve real social problems, such as the concept of salvation that a hundred schools of thought contend; Or born out of resentment, attacking real politics, such as Qu Yuan's work Li Sao. 4. Randomness: Randomness means that a writer can speak freely, say whatever he wants, and say whatever he wants. The original songs, myths and legends before the writing came into being naturally did what the human brain could think of and what the population could say.
