Liannan Yao Autonomous County, Qingyuan City, located in the northwest of the northern mountainous area of Guangdong, is the only place in my country where the Pai Yao live and where the Shuagetang is popular. Shuagetang is a large-scale cultural activity of the Yao people, mainly popular in the Pai Yao villages of six towns, including Sanpai (including Nangang), Woshui, Daping, Xiangping (including Panshi), and Sanjiang (including Jinkeng). The specific forms of performance include ancestor worship, going out of the singing hall, Guozhou dance, long drum, Yao song singing and duet, Fazhen performance, chasing and beating the black-faced man, etc. According to historical records, during the heyday of the Pai Yao during the Hongwu period of the Ming Dynasty (1368-1398), there was a complete Shuagetang, which has a history of more than 600 years. Shuagetang is a folk event that integrates the Liannan Pai Yao's commemoration of ancestors, reminiscing about history, celebrating the harvest, thanking and fulfilling vows, spreading knowledge and mass entertainment activities. The big singing hall lasts for three days and is held every three or five years; the small singing hall lasts for one day and is held every two or three years. The meeting is held on the 16th day of the tenth lunar month, the birthday of Pangu Wangpo. The Pai Yao do not have their own writing system, so the singing hall has become an important carrier of cultural exchange and historical inheritance. The Yao Sutra recited in the singing hall provides strong evidence for the origin of the Pai Yao, and provides sufficient materials for the finalization time of the Yao division and the study of the folk beliefs and Yao Sutra creation of the Pai Yao. In addition, the Yao Sutra also reflects the ancient battles in Lingnan, and has a high historical research value in ethnology, sociology, and folklore. In addition, the exquisite headdresses and accessories, gorgeous costumes, unique long drums, master dances, and national folk instruments such as ox horns, gongs, suonas, mang flutes, May flutes, and flutes worn by the Yao people in the singing hall have a strong national artistic style and high artistic value. During the "Cultural Revolution", the singing hall was imprisoned. It was not until the late 1980s that the singing hall was initially restored.
