If you have published a paper, of course, you'd better make a copy in advance and give it to the teacher when you ask. If not, you can say that I had the idea of writing a paper, but I didn't publish it. I feel that this research is not deep enough, so I want to take the postgraduate entrance examination and continue my study with my tutor. If someone asks you what scientific research experience you have, just say so. For example, during your undergraduate years, you worked on a project and undertook a task with a teacher. A teacher has a national or provincial project. Whether science and engineering students have participated in invention patents or software copyrights, utility model design, etc.

On the basis of a certain understanding of the tutor's papers and works, if you can express your views in the interview, you can leave a deep impression on the tutor and reduce the brush rate. Moreover, we can write academic resumes purposefully according to the research direction of the tutor's thesis, and we can also read relevant books to accumulate for the interview of professional courses, killing two birds with one stone.
