The purpose of this study is to examine the historical background and culture of the four ethnic groups, namely, Mongolian, Uyghur, Tibetan, and Korean-Chinese, and to derive cultural characteristics of their folk dances by examining how their ethnic culture has been embodied in the dances. In China, a multiethnic, multicultural country with 56 ethnic groups, dances performed in each ethnic group is part of life formed based on the cultural and geographical background of the group, and the contents, form, rhythm, and style of the dances were all formed and inherited in various ways due to differences in lifestyle and religious culture. Among those ethnic groups, Mongolian, Uyghur, Tibetan, and Korean-Chinese are the most localized ethnic minorities distributed around China's borders, and their folk dances have spread nationwide faster than those of any other ethnic groups. In order to promote the preservation and development of civil folk dances, it is necessary to examine the folk dances that are currently being preserved and developed and understand their cultural characteristics. By examining these characteristics, this study seeks to contribute to accurate perception of civil folk dances and to their preservation and development.

With the prosperity of Chinese folk dance creations, especially the development of the dance performances represented by the Lotus Awards and Tao Li Cup, the technical skills of national folk dances are further promoted to a new height. Its development, however, generates two problems. First of all, the technical characteristics of styles are diminishing and tend tocome be homogeneous. Second, the pursuit of techniques with ultra-high difficulties makes the creative vocabularies hollow and devoid of content and typicality. This paper adopts the methods of investigation, observation and literature research to analyze the related technical skills in the creation of folk dances in Chinese dance circles. The purpose is to emphasize that the creation of Chinese folk dances should be traced back to their origins, and to bring forth new ideas in three aspects: stylization, emotionalization and artistry, starting from the characteristics of technical skills. In order to break through, its form should be more epitomous in culture and more typical in aesthetics. Only in this way can the technical skills of Chinese folk dances become truly prosperous.

This study examines the court and private versions of Yukhwadae (六花隊, Formation of six flowers) of the Joseon Dynasty in order to identify the pattern of coexistent and exchange of different cultures such as the royal court and the private sector. The development and changes of Yukhwadae illustrate a way of cultural transformation of dance.

To clarify the cultural transformation of Yukhwadae, this study analyzes the court's documentary records centering on Akhak Gyebum (Canon of Traditional Music) and the civilian literature records centering on the records of Gyobang Gayo (Song of Gyobang).

In Yukhwadae, which was transferred to the public from the courts revealed through literature, all ritual articles of Dangakjeongjae, such as jukganja (pole bearer), uimul (instrument), and changsa (song or chant), were eliminated, and the overall format was simplified. In addition, the content of dance was selectively accepted and reinterpreted, and costumes and music were transformed to be suitable for the private sector. Therefore, through this study, it was found that the strict form of the royal court Yukhwadae was exchanged with the private sector and transformed into a popular and diverse form suitable for civilian performances.

As such, it was found through the results of this study that different cultures were exchanged between the royal court and the private sector during the Joseon Dynasty. I suggest to consider dance from a perspective of cultural exchange, researching various dance cultural exchanges, and contributing to the development of dance.
