Bayu Dance is a dance that came from the Yi people (Ban Dunman) in the southwest of China in the early Western Han Dynasty. Liu Bang, Emperor Gaozu of Han Dynasty, recruited a group of Yi people as strikers. Yi people are brave and good at fighting, and they are good at dancing. Liu bang ordered musicians to learn and adapt their dances. Because the Yi people live in Yushui, Ba County, this dance is called Bayu Dance. After being introduced into the court, it became a court dance and was used to perform military battle scenes at court banquets. During the performance, dancers dressed in armor, armed with spears and crossbows, sang the ancient battle songs of the Yi people and danced while singing. There are 36 dancers, which are group dances. Because this kind of dance is a kind of military music dance, Emperor Aidi of Han Dynasty still thought it necessary to stop 36 drummers in Bayu Middle School and hand them over to Da Le to be included in the Yayue dance system. Its accompaniment instruments are mainly bronze drums, accompanied by percussion, vibration and fiddling. There are four dances: Song of Mao Yu, Song of Anu, Song of Antai and Song of Hangzhou Ci. Bayu Dance developed into a temple fair dance in Wei and Jin Dynasties. Bayu Dance occupies an important position in the ancient dance art in China.
