Stamp the internship appraisal form directly to the competent department. Under normal circumstances, as long as it is not out of line during the internship, it will basically be stamped. Stamping the internship appraisal form means that you have completed this internship, and the competent department will give a final opinion and stamp it according to your performance during the whole internship. Some majors can't graduate without internship, and they can't get the corresponding certificates.
