Dance historian Fei Bingxun believes that "dance spin" does not refer to a specific content of a specific program, nor is it a general term for all dance programs, but rather refers to other than team dances, dance team, interspersed in the square art or banquet rehearsals in the music of a single or two-person performance in the dance of a large song and a shorter unarmed dance program. Meng Yuanlao describes "a Liao man in a small turban with no feet, stepping on a crossbow and dancing with a spinning arrow" (see Tokyo Menghua Lu (Tokyo Dreaming Book)). When Wu Zimu describes "a Liao man with a footless turban and a small jacket stepping on a crossbow, dancing and hitting arrows" (in Tokyo Menghuaju (Tokyo Dreams) Records), the term "dancing and spinning" seems to be a generic term for the movement. When Wu Zimu describes "in the marketplace, there are musicians in groups of three or five, with one or two girls dancing and spinning" (in Mengliang lu (Records of Dreams and Sorghums)), the term "dancing and spinning" seems to be a generic term for movement. When Wu Zimu describes "a group of three or five musicians in the market, holding one or two girls in a dance circle" (in Mengliang Lu, Brothels and Music), the term "dance circle" emphasizes the process of movement, and evokes the characteristic of "rotation".
