Comrade Wang Li once said: "When we engage in scientific research, we should first use induction and then deduction. It can't be reversed, and it will be broken in turn. " ("Talking about Writing Papers") Inductive requirements are based on a large number of materials. Without materials, any incisive analysis or novel ideas are impossible. It is an important preparation for writing a good paper to possess and digest the materials as fully as possible.

1. 1 Extensive collection and reading

The questions raised in the paper should be concentrated, but the materials should be collected as widely as possible. Generally speaking, at least the following three aspects of knowledge and information should be prepared.

1) Full familiarity with the special materials that can reflect the specific characteristics of the research object is a necessary prerequisite for a correct understanding of the object. In addition to directly understanding the specific characteristics of the research object itself (through all the works of relevant writers, all kinds of knowledge about the problem, …), we should also grasp all social and historical conditions or spiritual and material factors that can affect the emergence, development and change of the research object. Only by mastering these materials as comprehensively as possible. Doing research can fully reflect the "living soul" of Marxism-a concrete analysis of the specific situation.

2) Theoretical preparation as a clear direction and ideological guidance.

The so-called scientific research is to find out essential and regular things from concrete things and phenomena through correct and rigorous analysis, generalization and abstract work. This work itself must have correct theoretical guidance (professional theory and philosophy as world outlook and methodology). The history of scientific practice and development also tells us that to carry out a research work, we need not only enough professional theories and knowledge, but also the ability to be widely familiar with the theories and knowledge of other related disciplines. Through the mutual infiltration of theories and methods of different disciplines, we can inspire each other (for example, systematically analyze the aesthetic characteristics and social functions of artistic images; Introduce the method of fuzzy mathematics into rhetoric research)
