Which is better, painting, calligraphy or dance music?

It depends on your purpose. If it is to cultivate sentiment, painting, calligraphy and dancing can be done. If you want to make a living by taking a career path, it depends on your own conditions. It is best to make a living by art, with large employment space, less age limit and strong market demand. I can't go into details because your question is too general. You can add questions and I will try my best to help you.
