These types are the general term for performance forms that are considered to meet the collective expectations of the nation, race or community. The history of the development of folk performing arts and international legislative practices have shown that the expression of folk performing arts has legal characteristics that are clearly different from the "works" in copyright law. The particularity of folk performing arts determines the characteristics of its expression. At the "Rights" held in Wuhan, scholars summarized the characteristics of folk art expression as diversity, uncertainty, inheritance, intangibility, practicality, and openness. Based on the above concepts, the expression of folk performing arts has three main characteristics. First, the diversity of expression. The expression form of folk performing arts is the folk songs, music, drama, dance and other performing arts forms performed by a certain social group and spread among the people. After it is produced, it will continue to innovate and enrich among regions and ethnic groups.

Since folk performing arts originate from the colorful lifestyle of the people and are not bound by the rules of "court art", the accompanying folk performing arts naturally compete for development, and the form changes with the times, from the initial juggling to traditional dance, from live performances of "hundreds of plays" to "human-machine cooperation" performances.
