“Sanyuesan Festival”, also called the “Cutworm Fair”, is a traditional festival of the Buyi people, at which in memory of cutworms, the Buyi people scatter fried corns on the slopes and sing folk songs to pray for a bumper harvest.
　　Now the “Cutworm Fair” has become “Sanyuesan Song Festival”. On every 3^rd day of the 3^rd lunar month, the Buyi people in Guiyang and nearby gather round the Xinbao town, Wudang district. They either join in the singing competition, or sing in antiphonal style by blowing the tree leaves in the dense forest, or travel in groups along the stream playing with the water and singing cheerfully. When finding each other congenial, they will present gifts to each other and then walk in pairs from the crowds into the woods.
