Art is an integral part of the humanities, and it is a science that studies art phenomena and their laws. The evolution of art history, art theory and art criticism are its main contents. Art studies should study artists, artistic creation, artistic appreciation, artistic activities and other artistic phenomena, as well as artistic thoughts, plastic aesthetics, art history and so on. In addition, art should also study its own history, that is, the history of art, just as philosophy should study the history of philosophy. Art can be studied in its own unique way, and it can also learn from the methods of philosophy, aesthetics, psychology, sociology and literature and art. Therefore, the research of art can also be combined with the research of other disciplines to form a marginal field of art research or a new interdisciplinary subject, such as art sociology, art psychology, art marketing, art informatics, art management and so on. Here, the meaning of the word "art" sometimes extends to the fields of plastic arts such as calligraphy and photography. Through this definition, the basic research objects of fine arts include art history, art criticism and art theory, which constitute the research on the phenomenon of "art" and form the basic framework of fine arts in China.
