It doesn't matter. For an influential example, Anhui University can use Alipay as a campus card, but students from the College of Arts and Media of Anhui University cannot use the student number of Anhui University to cook cards. As a student of Art and Media College of Anhui University, although he is a student of Anhui University, he is the student number of Anhui University, but you can't log on to the website of Anhui University with your student number. Understand? To some extent, Ann probably won't take you to play.
