I think it's incredible. I think the tutor's request is completely unreasonable. What kind of avatar students use is their personal freedom, which will not affect students and tutors to do research together, and will not have any influence on students and tutors. There is no reason for the tutor to force the students to change their faces. Moreover, to be a mentor, to be an enlightened and tolerant teacher, it is incredible to be able to do such a thing. It is totally unreasonable for the tutor to force the students to change their heads, which will cause a lot of troubles to the students, not only the distress of being forced to do things by others, but also the unhealthy mentality of doubting their own studies, because his tutor turned out to be such a person who interfered in the students' personal life regardless of the students' wishes, which will make the students doubt whether such a person can learn by himself better.

1. The tutor has no reason to force the students to change their heads. What kind of avatar students use is their personal life. Tutors have no reason to interfere in students' personal lives. Therefore, the tutor should not force the students to change their heads, and the tutor should not take the students' heads as the center. This is not normal.

Second, the tutor's behavior has an influence on students' psychology. The tutor's compulsive behavior will make students have a psychological shadow, and students will have doubts about their choice, because students choose tutors to improve their studies, but tutors are more concerned about whether students change their avatars according to their own wishes, which will cause great trouble to students.

Third, the tutor should reflect on his own behavior. As a mentor, you should not only preach and teach, but also set an example. As a tutor, I should be more tolerant and understand students. If the tutor really doesn't like the students' heads, I can put forward my own opinions and make the students willing to change their heads after good communication, instead of choosing to change their heads under the pressure of the tutor. A tutor should reflect on his behavior.
