Can a calligraphy teacher teach art

Calligraphy teachers can teach art, and calligraphy teachers are mostly art students. Art students can be teachers, but they should choose what teachers to be according to their majors. For example, an art student's major is broadcast host, so you can choose to be a broadcast teacher. If you majored in art when you were an art student, you can choose to be a teacher in the studio or an art teacher in school. Everything's fine.
