In addition, there are many kinds of art belonging to the category of human movement, such as acrobatics, mime, human sculpture, rhythmic gymnastics and so on. Therefore, dance is different from other human movement art is the main aspect: it is to dance movement as the main means of artistic expression, focusing on the expression of language and text or other means of artistic expression is difficult to express people's inner deep spiritual world - delicate emotions, profound ideas, distinctive character, and man and nature, man and society, man and man and the conflict between people and the people themselves, to create a vivid dance image that can be perceived by the people.
