Yes, the Guangzhou University City Card actually combines the student card with two Lingnantong cards, and the part of Lingnantong can continue to be used even after graduation. The part of the student card should be swiped into the library according to the situation of each school, such as Guanggong, but books cannot be borrowed. Specifically, every school will delete the student information from the card, so the functions related to the student information cannot be used.
