How did the Nuo opera of the Gelao nationality develop?

Nuo opera has a long history and originated from primitive religion, witchcraft, nature worship and ancestor worship. According to folklore, Grandpa Nuo and Niangniang Nuo gave birth to human beings, and the Gelao people regard Grandpa Nuo and Niangniang Nuo as their ancestors. Later, people prayed to their ancestors, grandfathers and queens to cure diseases and eliminate disasters, and prayed for their children to prolong their lives. Therefore, the Gelao people call the Nuo opera performance "a wish to Nuo". If you ask your ancestors to bless you, you will get happiness and reward, so there are sacrificial activities to reward and entertain God. As early as the pre-Qin period, there were witchcraft songs and exorcism to entertain gods and people. During the reign of Kangxi, Nuo opera developed rapidly to various places, forming different schools and artistic styles. Guizhou Nuo Opera has absorbed the artistic elements of lanterns. Therefore, Nuo Opera, also known as Tang Nuo Opera and Duangong Opera, is a form of opera formed by absorbing the essence of folk opera on the basis of folk sacrificial ceremonies. In Shang Dynasty, a fixed sacrificial ceremony was formed to exorcise ghosts and eliminate epidemics, which is Nuo dance.
