a popular genre of music called shidaiqu emerged in the 1920s. Shidaiqu is a fusion of Chinese and Western popular music, and Li Jinhui is considered to be founder of the genre. Popular singers in this genre in the 1930s and 1940s included Zhou Xuan, Li Xianglan and Yao Lee. After the 1942 Yan'an Forum on Literature and Art, a large-scale campaign was launched in the Communist controlled areas to adapt folk music to create revolutionary songs to educate the largely illiterate rural population on party goals. Musical forms considered superstitious or anti-revolutionary were repressed, and harmonies and bass lines were added to traditional songs. One example is The East Is Red, a folksong from northern Shaanxi which was adapted into a nationalist hymn. Of particular note is the composer, Xian Xinghai, who was active during this period, and composed the Yellow River Cantata which is the most well-known of all of his works. People's Republic of China (1949–1990s) The golden age of shidaiqu and the Seven great singing stars would come to an end when the Communist party denounced Chinese popular music as yellow music (pornography). Maoists considered pop music as a decline to the art form in mainland China. In 1949 the Kuomintang relocated to Taiwan, and the People's Republic of China was established. Revolutionary songs would become heavily promoted by the state. The Maoists, during the Cultural Revolution, pushed revolutionary music as the only acceptable genre; because of propaganda, this genre largely overshadowed all others and came almost to define mainland Chinese music. This is still, in some ways, an ongoing process, but some scholars and musicians (Chinese and otherwise) are trying to revive old music. After the Tiananmen Square protests of 1989, a new fast tempo Northwest Wind (xibeifeng, 西北風) style was launched by protesters to counter the government. The music would progress into Chinese rock, which remained popular in the 1990s. However, music in China is very much state-owned as the TV, media, and major concert halls are all controlled by the Communist party. The government mainly chose not to support Chinese rock by limiting its exposure and airtime. As a result, the genre never reached the mainstream in its entirety. People's Republic of China (2000s–present) Annual events such as the Midi Modern Music Festival in Beijing attracts tens of thousands of visitors. There was also the "Snow Mountain Music Festival" in Yunnan province 2002.
