In the early 1990s, many major Cantonese pop stars (such as Alan Tam, Leslie Cheung, Samuel Hui, Priscilla Chan and Joseph Koo) decided to retire because of the protests in China in 1989. Cantonese pop needed new talent to fill the gaps left by these retired stars, this led to the beginning of "the Four Heavenly Kings" or "四大天王" ("lit." Four Great Kings of Heaven): Jacky Jeung, Andy Lau, Aaron Kwok and Leon Lai. They were dominating the media in all forms, from magazines, TV, cinema to music.
