Graduation thesis is the last link for self-taught senior high school undergraduate candidates to complete their undergraduate studies. The writing of graduation thesis can be divided into two steps, namely, topic selection and research topic. Choosing a topic is the key to the success or failure of graduation thesis writing.

First, we should insist on choosing topics with scientific value and practical significance. A meaningless research, even if it takes a lot of energy and perfect expression, will be worthless.

Second, we should choose practical topics according to our own abilities. The writing of graduation thesis is a kind of creative labor, which requires not only the personal views and opinions of candidates, but also certain objective conditions. Because the subjective and objective conditions of candidates are different, they should also choose the topic according to their own specialties, interests and objective conditions.

Specifically, candidates can comprehensively consider the following three aspects:

First of all, there should be sufficient sources of information. "A clever woman can't cook without rice", and it is difficult to write a high-quality paper in the absence of information. Choosing a subject with rich data sources is very helpful for the in-depth research and development of the subject.

Secondly, we should have a strong interest in research. This can fully stimulate their research enthusiasm, arouse their initiative and enthusiasm, and can be completed with a positive attitude of concentration, carefulness, perseverance and patience.

Finally, we should be able to combine our professional knowledge. Every candidate, regardless of ability level or job position, has his own professional expertise. Choosing a subject that can combine one's own work and give full play to one's professional expertise is of great benefit to the successful completion of the research of the subject.
