1. Value principle. It is the main basis for choosing a topic. The first is the application value, which is an urgent problem to be solved in the construction of socialist material civilization and spiritual civilization. It can also be understood as the so-called "social hot issues". Second, the theoretical value. Some research projects are of great value for the development of science and culture, for solving theoretical problems, or for guiding the research of applied topics.

2. The principle of innovation. That is, the topic should be original, innovative and distinctive. In the process of topic selection, we should pay attention to two points. First, we should prevent the same topic and follow in the footsteps of others. The second is to consider the topic and whether it can develop new achievements.

3. The principle of feasibility. Conduct scientific research writing according to your own subjective and objective conditions. When choosing a scientific research topic, we should not only consider the necessity of research, but also consider the possibility of completing research and writing by ourselves.
