Not a book refers to the first batch of undergraduate enrollment. According to the hand-held college entrance examination, Changchun University enrolled two batches of undergraduate students in Shanxi and Heilongjiang, so the school is the second institution in these areas. Beijing, northern Liaoning and other places have abolished the division between the first batch of undergraduate courses and the second batch of undergraduate courses, and merged them into the first batch of undergraduate courses for enrollment, so the school is an undergraduate institution in these areas. So Changchun University is not a book.
