The topic of this paper lies in innovation. The topic selection is innovative, which can be a new viewpoint, a new method, a new angle and so on. Topic selection innovation can take the following three forms:

First, for graduate students, they can explore old problems with new angles or new research methods. In the process of social development, the previous studies were all carried out under a specific social background, and it is inevitable that there will be mistakes or shortcomings. We look for a breakthrough through the shortcomings of their research, and discuss it from a new angle, a new method and a deeper level, so as to draw a more perfect conclusion.

Second, use the original theories and methods to analyze and solve new problems. Because there will be many new problems in social life, we can solve them on the basis of the original theory and using the theories and experiences of our predecessors.

Third, it is also an innovation to question the existing viewpoints and methods. With the continuous development of science and technology, people's understanding of the problem is deepening. Some theories and viewpoints have always been thought to be right, but in fact they may be wrong, so we should re-recognize them. For example:? Parity conservation law? Originally, it was one of the principles agreed by the physics community, which became a recognized fact, but it has been proved by experimental facts. Parity conservation law? Not universally applicable.

In a word, the topic selection of graduation thesis is a comprehensive and difficult work. We must make use of our theoretical knowledge, follow the above principles of professionalism, value, feasibility and innovation, and determine the appropriate topic through our own serious thinking, so as to lay a good foundation for thesis writing.
