Calligraphy major, perhaps no school has more prospects. This is determined by the national conditions.
There are very few calligraphers who make a living by their majors. Unlike painters, they can also get a guarantee in the painting academy. The Ministry of Education requires primary and junior high schools to offer calligraphy courses, but it will not be an exam-oriented subject. The situation can be imagined. But perhaps, some good schools may also recruit real professionals to teach in this matter, which is determined by the knowledge and responsibility of the principal.
At present, the situation of calligraphy major is similar to that of entertainment circle, even more difficult. To be stronger, you need to know about being famous. Otherwise, you may not be able to satisfy your talents. As a hobby, that's another matter.
Culture will always be revived, but it will take time.
Good luck!
