Art is the organic product of people's comprehensive psychological activities such as knowledge, emotion, ideals and ideas, and it is the image expression of people's real life and spiritual world. Art belongs to the category of entertainment and game culture, and it is a cultural phenomenon created by people to satisfy their subjective defects in emotional organs and comfort their behavior. The essential feature of this cultural phenomenon is to create virtual human real life with language. Art is a cultural form of people's emotional and ideological exchange, which is based on language, so the basis of art is human language.

Art can be defined as "technology and its products whose main purpose is to create beauty". Art needs technology, but it is not technology. But the next question is "What kind of technology is art?" The ancient Greeks introduced the concept of "beauty", but the division of technology did not become simple because of the introduction of this concept. On the contrary, it has become more complicated than before. Because explaining "beauty" itself is not easier than explaining art.

Modern Chinese Dictionary says that art is "a social ideology that reflects reality with images, but is more typical than objectivity."

The original meaning of "art" in western languages is "artificial creation". Epistemology holds that art is a reflection of nature in people's minds and an ideology; According to the theory of practice, art is the processing and transformation of nature by human beings, and it is a kind of labor production, so art is called "the second nature". Human labor is to create material wealth and spiritual wealth. All art must have a creative subject and object. Therefore, both human and material conditions are needed. Humanistic conditions include the artist's natural endowment, life experience and cultural education; The conditions of things include social types, spirit of the times, national characteristics, social realities and problems, and are the objects that need to be continuously processed and transformed; In addition, tools and media for processing and transformation should be added. So art is inseparable from people and things. Like aesthetic feeling, it is also the unity of subjective and objective.

1999 edition of Ci Hai explains the connotation and extension of art;

"Human beings regard emotion and imagination as a special way to grasp the world, that is, to reproduce reality and express emotional ideals through aesthetic creation activities, and to realize the mutual objectification of aesthetic subject and aesthetic object in imagination. Specifically, they are the image reflection of people's real life and spiritual world, and also the organic product of the artist's comprehensive psychological activities such as perception, emotion, ideal and concept. As a social ideology, art mainly meets people's various aesthetic needs, thus playing a subtle role in social life, especially in the field of human spirit. According to the different means and ways of expression, it can be divided into performing arts (music and dance), plastic arts (painting, sculpture and architecture), language arts (literature) and comprehensive arts (drama, film and television). According to the temporal and spatial nature of performance, it can be divided into time art (music), space art (painting, sculpture, architecture) and time-space juxtaposition art (literature, drama, film and television).
