Brothers and sisters at Nanjing University of the Arts, please help? Are calligraphy classes in your school open to the public? I want to sit in on your course, thank you

I am a student at Nanyit University, but not from the calligraphy department. The professional courses in our college are all in small classes, and the teacher will take roll call, and there are only a dozen or so people in each class, all of whom know each other, so I thought If you want to audit, you can choose to study at the Academy of Fine Arts, so that you can participate in all professional courses.
