It depends. Generally, you should talk to your tutor first. If the tutor here agrees, the college will agree to stamp it (soon if it goes well). Then we will go to the graduate school to go through the formalities of student status change (withdrawal), and all personal information will be cancelled. All departments should report and seal (accommodation, library, network center, security office, archives room, accounting office, etc.). ). Finally, go back to the graduate school to go through the final formalities and leave school.
