Based on the systematic discussion of Kunqu and neoclassical dance, this paper first expounds the formation and evolution of Kunqu, then analyzes the structure of Kunqu and discusses the value and significance of Kunqu.This paper puts forward the significance of Kun dance research, the problems existing in classical dance, and how to inherit and develop the viewpoints.In addition, this paper focuses on the structure of Kun dance, including ideology, body movement, spatial structure and performance, and analyzes the status, aesthetic value, teaching value and cultural value of Kun dance. Combining the study, teaching and experience of Kun dance, the author puts forward four academic values of Kun dance: first, to provide basis for tracing the origin and inheritance of classical dance.Through the background, evolution and development of Kun dance, and the detailed explanation of the other three classical dance schools, this study further summarizes the thought and culture of Kun dance. Secondly, it becomes the theoretical basis for studying the philosophical thoughts of classical dance.Kunqu dance, which inherits Kunqu Opera, is consistent with China's "integration of heaven and man", and its body movements, emotions, and dance moves are all full of elements of perfection, abundance and flexibility. Thirdly, it is of great value to study the inheritance of Kunqu Opera.Kunqu Opera has been an art in China for hundreds of years. Kunqu dance is the cultural extension of Kunqu Opera and the carrier of Kunqu Opera. Fourth, supplementary information to the neoclassical dance system.The training methods of Chinese dance are no longer limited to western ballet, but can use the techniques of the diversification of Kun dance track, 27 position and space movement. Of course, there are some problems in the development of Kun dance. First, because of its short history, there is a lack of theoretical research at home and abroad.Second, even though Kunming has achieved its university education, few people have completed their studies and taken up Kunming jobs.Third, because there are fewer experts and performers in Kun dance, there is a relative shortage of works.Kun dance is the birth and development of traditional culture Kunqu, its value and significance are very important.Therefore, this study can provide an important basis for the study of classical Kun dance genre, and Korea whether there is a relationship between them and whether they help and promote each other will be an important research direction in the future.
