What about the nominal name? I suggest the following treatment scheme:

1. The tutor is the first author, and the students are the co-authors of * * * *: the main achievements are completed by the tutor himself, and the students participate in the main research work;

2. The student is the first author and the tutor is the correspondent author: if it is the research work of the student's master's thesis or doctoral thesis, the main research work is completed by the student under the guidance of the tutor, and the manuscript of the thesis is revised and improved by the tutor;

3. The student is the first author and correspondent, and the tutor is the co-author of * * * *: If the research work is completed with the support of the tutor project, the tutor will participate in the discussion during the writing of the paper, and some will participate in the revision and improvement of the manuscript;

4. The student is the first author or independent author, and the tutor is not nominal: if the research work is completed with the support of the project applied by the student independently, the tutor only participates in some discussions and suggestions in the research process and has no contribution to the paper.
