As a doctor with the highest gold content in a degree certificate, many people can work hard for it for several years. As we all know, if a doctoral student wants to get a doctoral degree, he needs to be affirmed by the doctoral supervisor, but it is precisely because of this system that there have been many chaos. Doctoral tutors are learned in the eyes of most people, and most doctoral tutors have excellent professional ethics, which is undeniable. However, in such an excellent atmosphere, there will still be many tutors with corrupt professional ethics, which is inevitable. In recent years, many doctoral tutors abuse their power to make students do things other than degree research. The system introduced by the Ministry of Education is committed to solving this problem. Although this system can solve the problem of abuse of power by doctoral supervisors to a great extent, it may also cause some inevitable disadvantages.

The system recently implemented by the Ministry of Education has undoubtedly solved the problem of abuse of power by doctoral supervisors to a great extent. Because doctoral tutors abuse their power, mainly because students can't change when they choose a tutor. To put it simply, if you meet a tutor with a bad personality, even if there is nothing wrong with yourself, you may be sentenced to fail the examination. After all, it is the tutor who decides whether you can get a doctorate or not. Moreover, emotionally, if there is a conflict with the tutor carelessly, the tutor is also prone to negative emotions, which will affect the fairness of the assessment. If there are contradictions, you can change to a doctoral tutor, which can solve these problems.

But after all, everything has advantages and disadvantages, and the disadvantages of doing so are obvious, that is, it may cause some students to disrespect doctoral supervisors. Although doctoral students already have high academic qualifications, academic qualifications are not the standard for judging their character. Even with high academic qualifications, there will still be some arrogant people. The intuitive problem brought by the implementation of this system is that students may not attach importance to the relationship between teachers and students, and even cause confusion of disrespect for teachers.

To sum up, the contradictory doctoral supervisor replacement system introduced by the Ministry of Education has advantages and disadvantages in detail, but it is undeniable that this system has greatly guaranteed the interests and safety of students and made the examination process of doctoral students more fair and just.
