It is more difficult, because the blind evaluation of doctoral thesis completely blocks the personal information such as tutors and students, that is, the teacher who completely evaluates this thesis simply doesn't know who the personal information such as tutors and students are.

Therefore, blind trial is relatively objective, but relatively difficult, and it will take a long time. And it will be harder to be excellent.

Because the teacher who comes to evaluate this paper will not care where you are a student or who is the tutor of this paper, but will judge it entirely by whether the paper is well written or not.

I won't consider anything else, so it's still difficult to be excellent. If your hard power is not strong enough, you may not get excellent. Blind examination and passing the doctoral thesis are all problems, let alone an excellent doctoral thesis.
