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). Special materials that can reflect the specific characteristics of the research object itself.

Fully familiar with the object is an indispensable prerequisite for correctly understanding the object. In addition to directly understanding the specific characteristics of the research object itself, 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. Only by conducting research can we fully embody Marxism? A concrete analysis of the living soul.

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

The history of scientific practice and development 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 and inspiration of theories and methods of different disciplines, new discoveries and breakthroughs can often be better brought.

Others have also expressed their opinions on this issue.

Try to collect information in this regard. Problems that others have solved naturally do not need repeated efforts; Fully absorbing the existing experience of others, or understanding the focus of others' problems, and carefully comparing and studying different viewpoints can not only avoid detours, but also help to find problems.

2. Carefully sort out the screening.

In order to make materials work, it is necessary to use scientific viewpoints and methods to get the essence from the rough, to get rid of the false and to keep the true, to make the material system orderly, and to help analyze and solve problems. Decorative materials generally have the following forms:

1). Make a directory index of documents and materials. You can use relevant ready-made materials (library, reference room directory card, newspaper index, etc.). ) according to your own topic.

2). Newspaper clippings, notes and summary cards. The collection and arrangement of such data must be clear. One is to clearly indicate the author, title, source and publication date of each document, and the other is to classify it carefully and reasonably.

3). Memorabilia, chronology or translation chronology. Through the compilation of such materials, the overall impression of the research object can be strengthened, which is helpful to deepen the research on a certain topic and a certain aspect on the basis of a comprehensive understanding.

Have you mastered all these skills?
