We all do this at school. When doing the graduation thesis experiment, although it is nominally with teacher A, it is actually with teacher B, because many times, teachers are very cooperative.

I wonder what your major is like? I majored in engineering and graduated from 19. This year is the last graduation of my tutor. Two of them are under my tutor's name, but there are actually other teachers to guide them. In my opinion, the tutor is too old to do it, and the two outsourced brothers are developing better. Of course, this is also related to individuals.

The outsourced younger brothers usually work with their actual instructors, and my instructors only occasionally ask about their work progress and get to know the situation. In addition, the actual instructors of my outsourcing younger brother are all young teachers who need to improve their professional titles, so these two younger brothers have lived a full life and learned a lot.

Tell me about your situation. I suggest you actually know the personalities of your two mentors and the research prospects of your actual mentor. If you have brothers and sisters in the same situation as you, you can learn about their development in three years.

Personally, I guess that your actual tutor may continue to need people because of the heavy workload and few students, but the number of places is limited, so he hangs you under the name of other tutors, which is discussed between their tutors.

If you agree with this situation, it may happen in your graduate career. Eating, activities, entertainment and communication in the research group are all doubled.

It will be very troublesome (because I am introverted and unsociable), and then you need to run on both sides, open the topic and defend what needs to be reported, such as writing the tutor's opinion, reporting and signing, which is also doubly troublesome.
