Nollville further emphasized and analyzed: "There are three kinds of dances, each with its own segment and face ... No matter what kind of dance, dancers should imitate, mime and concentrate on performance. Therefore, the only problem is to make the dance language have different levels of elegance with the solemnity of the theme and the different kinds of dances. The solemn heroic epic dance itself contains tragedy; Mixed, or semi-solemn, also known as semi-character dance, is a noble comedy, also known as elegant comedy. Funny dance is inappropriately called pantomime because it has no meaning. It just borrows its characteristics from an interesting comedy, which is a pleasant and happy comedy ... (solemn dance, semi-personality dance, funny dance) Three kinds of dancers have their own division of labor, and their talents vary according to their bodies, faces and professional research. The first one should be tall, the second one should be charming and the third one should be funny. The first dance is based on history, myths and legends, the second is based on pastoral, and the third is based on vulgar rural scenes. "
