The introduction shall include the following contents:

1. Significance of the topic: The content to be written in this part is what problems this article is going to solve, why it should be solved, and what harm or consequences it will have if it is not solved. In other words, the author found a realistic problem that must be studied and solved.

2. Research scope: That is to say, to what extent can this paper solve the above problems, what problems can't be solved and what problems remain to be solved. It may be necessary to define the corresponding concepts.

3. Research methods: Most master's dissertations are not easy to make full use of normative analysis, and empirical research is largely unrealistic. Because the research time and funds do not allow the author to conduct empirical analysis. However, if you can make full use of the existing materials, you can also write a good paper. Comparative research will use some more or less. Other methods are selected according to the author's ability.

4. Research ideas and approaches or technical routes: This part is not necessary and can be selected according to the situation. To sum up, the problem is the most important. The success or failure of a paper depends on whether the problem to be studied is valuable and clear.
