The southwestern provinces of Guangxi , Guizhou , and Yunnan make up a mountainous region with the greatest cultural diversity in China. The Zhuang people who live in Guangxi Zhuang Autonomous Region enjoy singing shange in pairs or groups of five to six people. While majority of shange are about love between a man and a woman, some narrate epic tales. They can also be improvised in surprising ways to match the situation.\n\nThe Miao people, characterized by the unique hairstyles of the women, are scattered around Guangxi Province, Guizhou Province, and other parts of southwestern China. They have a unique singing technique that involves drawing out a single note as long as possible. Using this technique, they sing feige that sounds like flying birds and jiuge . The lusheng music played by men is also worth a listen.\n\nThe Kam (Dong) people live in Guizhou and are well known in China as the most vocally gifted tribe. Each village has several singing groups comprised of several dozen people, organized by gender and age. These groups sing dage , which are traditional polyphonic songs. The gulou and dage are such famous symbols of the Kam people and are used in tourism programs as well.\n\nAlthough there are many ethnic groups in Yunnan province, the Yi people are well known for their singing. Yi women sing songs with extremely high pitches to the accompaniment of yueqin played by the men. The Yi are also famous for their mass dances and singing parties during summer bonfire festival.
