Graduation thesis is the last link for undergraduates majoring in higher education self-study examination to complete their undergraduate studies. For candidates, it is a summative and independent assignment, which aims to summarize the learning results and cultivate the ability to solve practical problems by comprehensively applying the learned knowledge. Stylistically speaking, it is also a meaningful essay for scientific research and exploration of practical or theoretical problems in a certain professional field. The writing of graduation thesis can be divided into two steps, namely, topic selection and research topic.

The first is the topic selection. Topic selection is the key to success or failure of thesis writing. Because choosing a topic is the first step in writing a graduation thesis, it is actually to determine the question of "what to write", that is, to determine the direction of scientific research. If "what to write" is not clear, "how to write" is impossible.

The practice and requirement of the Self-taught Examination Office of the Ministry of Education on the topic selection of graduation thesis is that "in order to encourage the combination of theory and work practice, candidates can put forward the topic selection according to their own work and submit it to the examiner's school for approval. Thesis topics can also be published by the examiner's school, and candidates can choose by themselves. The overall requirements of graduation thesis should be consistent with ordinary full-time colleges and universities, so as to test candidates' comprehensive application of professional knowledge through thesis writing and defense assessment. " However, regardless of whether candidates choose their own topics at will or choose from the designated topics announced by the examiner colleges, they should insist on choosing practical topics with scientific value and practical significance. Choosing the right topic is half the battle for graduation thesis.
