This right is simply that you have the right to choose your own tutor. If not, you have obvious contradiction with each other. You can submit the corresponding materials to choose a replacement tutor.

When graduate students reach the doctoral stage, especially when you can reach the doctoral stage, basically your tutor will spend more time with you, because he doesn't take many people with him. He will not only teach you something practical and useful, but also let you help him reduce his workload. Sometimes some simple junior jobs will be left to you, and private tutors generally won't give you any service fees. It won't let you do it for nothing, the two are mutually beneficial. Nowadays, many doctoral students are academic, and teachers don't call them teachers and bosses. This is an ideal relationship and a normal relationship, but it doesn't rule out some special ones, such as your teacher doesn't like you at all and sticks to you all the time.
An undergraduate teacher, he can't specifically card you or anything, and the obstacles he can cause you are limited.
