Tutors attach great importance to and recognize students' comprehensive ability. The tutor's choice to let you study PhD is mostly well thought out. The tutor has followed the students for two or three years and has a deep understanding of their real strength. If the students' academic research and comprehensive practical ability are not excellent, then the tutor will not recommend the students to continue their doctoral studies. It can be seen that the tutor's recommendation for doctoral studies is recognition of students' own academic research and innovation ability, which is also the advantage of students' doctoral studies. I hope the students I bring can have a deeper development in the field of academic research. After all, the tutor and the students have been together for two or three years, and there has been a deep affection between the students and the teachers. As a tutor, I very much hope that my students can get along with themselves for a few more years, and I also hope that students can make greater achievements in the future, and studying for a doctorate is one of the best ways at present. After graduating from doctor's degree, students get much higher treatment than master's degree, which not only greatly improves the academic research field, but also improves the work treatment, which is one of the important reasons why the tutor recommends the doctor.
