During the interview, the tutor will ask the candidate if there is any paper published. If you have papers and works, you'd better copy them in advance and hand them to the teacher in person. If not, you can tell them what you think about scientific research.
I have participated in relevant experiments and published papers, which is undoubtedly helpful for postgraduate entrance examination and re-examination. Because many students have no scientific research experience during their college years, let alone publish papers.
