The characteristics of literary content are that the content of literature reflects people's knowledge level in a certain social and historical stage; The existing forms of documents (such as recording means, writing materials, composition and communication methods, etc.). ) were influenced and restricted by the development level of social science, technology and culture at that time.
The level of social development determines the content and form of literature, and the inheritance, dissemination and creative application of literature react on society and become a powerful factor of social development. Gorky, a famous writer in the former Soviet Union, famously said: "Books are the ladder of human progress" in this sense.
Monographs (including historical records in ancient books) are works that comprehensively and systematically discuss a subject or a topic. Generally, it is the result of careful and systematic investigation or research on specific problems. Monographs are usually the author's statement of "one family" and his own views and understanding, rather than simply stating many statements; Monographs are generally long and can be discussed in depth and comprehensively around larger and complex issues. They have the characteristics of extensive content, systematic discussion and mature views. They are generally the embodiment of important scientific research achievements and have high academic reference value.
