I like calligraphy and want to improve my calligraphy. Does Nanyi have any further research in this field?

Your situation doesn't seem to agree with your idea. What does a regular calligraphy institute mean? There are no amateurs in regular calligraphy colleges, and they have academic qualifications. If you are an amateur and want to be formal, you have to go to an amateur formal calligraphy school. Amateur refers to studying in spare time, and formal refers to a specialized calligraphy college. For example, some calligraphy training classes, advanced classes and seminars held by colleges with calligraphy majors belong to amateur regular calligraphy colleges. You have the right to find it, some need entrance exams, and some are exempt from exams. All over the country, choose according to your own situation.
