The instructor's signature of the internship manual is the assistant's signature, which is not allowed. The internship manual records the internship time, internship unit, internship position and detailed daily work of students. Teachers of the school regularly check, and after the internship, hand it over to the school together with the Student Internship Registration Form, which will be archived by the school as an internship teaching achievement. The internship manual can't be signed on behalf of students, which is closely related to future employment.
