Does Chyi Chin's calligraphy and painting refer to literature or calligraphy?

If you choose between "literature" and "calligraphy", it is "literature". But I personally think that the scope should be wider than literature, because in ancient times, women didn't read books, and when it comes to "being proficient in everything", they are very comprehensive talents, so books here should refer to a wide range of knowledge, just like "reading" in our time, which generally refers to learning.
