Abstract art refers to any art that simplifies or completely separates the description of real natural objects. Its aesthetic content is expressed by the form combination or structure of shape, line and color. Sometimes the theme of abstract art is real, but it is difficult to recognize the original appearance due to excessive stylization, fuzziness, overlapping or decomposition to the basic form.

Abstract art uses the visual language of shape, form, color and line to create a composition that may have a certain degree of independence from the visual reference in the world. Abstract refers to the visual effect produced by simplifying or rearranging the appearance of natural objects, or the arrangement of non reproducible works is only to meet the artist's organization or performance of the picture. The degree of abstraction varies in all works of art, from reappearance to non concrete art.
