Can I study calligraphy and Japanese alone?

Of course. Calligraphy is a kind of art, and exams are usually included in art, so you can do it alone. As of June 14, 2023, a few Japanese universities or individual majors in some high school universities, such as Beijing Foreign Studies University and Northeast Normal University, can do it alone. Japanese candidates can apply for Japanese majors, and both of them can be recruited separately. Individual enrollment is a mechanism for the Ministry of Education to further improve the higher vocational education system with China characteristics and the diversified selection and admission of higher education.
