Because the opening report is just a plan you made before the formal research, but if you find it difficult to implement and there are too many loopholes in the process, you may change your perspective, change the theme of the research, or concentrate more, or turn to another topic that you are more interested in.

There is another situation, that is, when writing the opening report, you didn't take it seriously, the tutor was not responsible, the opening defense team was not in your field, or they were not responsible, or they were very responsible, and gave you very good suggestions for modifying the topic.

Or your school doesn't have the link of opening a defense at all, so that your poor opening report can get away with it. Later, when doing research, I found that the topic was too big to do at all; Or the method is not feasible; Too little or no funds; Or the information can't be found at all, or the opening report written by yourself is too rough to guide your own research.

At this time, you have made great progress by carefully reading the previous literature, discovered your previous shallowness and ignorance, and discovered new topics worth doing and how to do it. At this time, it is natural for you to change the subject.

As for the opening report, it is only a link in the whole research process. If we can reach an agreement, of course, it is best, but if it is really like what is said here, we might as well boldly abandon the original topic. What's more, when marking papers, you generally don't read the opening report.

Thesis:

An academic thesis written by a degree applicant is called a degree thesis. This kind of thesis is an important condition for evaluating whether an applicant can be awarded a degree. Degree applicants will be awarded if they can pass the required course examinations and pass the thesis examination and defense.

If an applicant for a degree passes the course examination, but his thesis is rated as unqualified in the defense, then he will not be awarded a degree. A graduation thesis that is qualified to apply for a degree and written for it is called a dissertation and a bachelor's dissertation. A bachelor's degree thesis is both a degree thesis and a graduation thesis.
