Dance is a performing art, which uses the body to complete various elegant or difficult movements, usually accompanied by music, and rhythmic movements are the main means of expression. It usually uses music and other props.

Dance itself has multiple social meanings and functions, including sports, socialization, courtship, sacrifice, etiquette and so on. Before the origin of human civilization, dance was very important in ceremony, etiquette, celebration and entertainment. Dance appeared in China five thousand years ago. It was born in slave society and developed into a certain feature in Qin and Han Dynasties.

Art is a big family of human aesthetic activities, and its members include literature, fine arts, music, dance, drama, movies, folk art and acrobatics. Various arts reflect social life and express people's thoughts and feelings, but the reflection and expression of art is not the abstract reflection and expression of general concepts, but the reflection and manifestation of individual concrete images and aesthetics.

The so-called aesthetic reflection and expression means that artists choose, summarize and process social life according to their own aesthetic tastes and ideals, and creatively reflect and express according to the characteristics and laws of art.

Dance movements in dance works should also have certain skills, and dancers should have high-level skills such as jumping, rotating, tumbling, softening and controlling. However, performing high-level skills in dance works is not an end in itself, but a means to express characters' thoughts and feelings and shape their character and mental outlook.
