What are the advantages of learning calligraphy and Chinese painting?

First, cultivate self-cultivation and interest; Then there are many choices in the future career. I study calligraphy, and my teacher is an excellent teacher in Zhejiang Province, because his calligraphy is good. As long as you are willing to work hard to practice calligraphy, just like my teacher, who teaches calligraphy in my school, the salary is higher than that of the principal. His students go to the Academy of Fine Arts and Zhejiang University because of their good calligraphy and good study. In fact, I think it's good to learn these things as a kind of interest, even if I can't eat them as food or show them off to my friends. (I don't know this aspect thoroughly, please forgive me.)
