 Today, the popularity of Nuo opera has declined and it can normally only be seen during the Spring Festival and other important traditional Chinese holidays, in remote mountainous areas, such as Guizhou, Hunan, Jiangxi, Yunnan, Sichuan, and Anhui provinces, inhabited mostly by minority ethnic groups.After the People's Republic of China was established in 1949, the influence and popularity of Nuo opera was suppressed by the Chinese government, because the superstitious elements in Nuo opera were contrary to the Constitution of the Communist Party of China which advocated atheism.Recently (probably after the year 2000), scholars from both China and abroad started becoming interested in "nuo" opera again because of its precious historical value.
