In mainland China, the music industry was freed from state restriction in 1978, and regional recording companies were established in Guangzhou, Shanghai and Beijing in the 1980s with local singers. Pop music in China in this period was dominated by Mandopop songs from Taiwan and Cantopop from Hong Kong, however the 1980s saw the beginning of rock music in China, with the emergence of singer-songwriters such as Cui Jian, followed by others such as He Yong and bands such as Tang Dynasty which became popular in the 1990s.
