Samuel Hui Koon-kit, usually known as Sam Hui, is a Hong Kong musician, singer, songwriter and actor. He is credited with popularising Cantopop both via the infusion of Western-style music and his usage of vernacular Cantonese rather than written vernacular Chinese in biting lyrics that addressed contemporary problems and concerns. Hui is considered by some to be the first major superstar of Cantopop, known as the God of Song. As an actor, he is well-known for portraying the main character "King Kong" in five installments of the Aces Go Places film series.

Cantopop is a genre of pop music sung in Cantonese. Cantopop is also used to refer to the cultural context of its production and consumption. The genre began in the 1970s and became associated with Hong Kong popular music from the middle of the decade. Cantopop then reached its height of popularity in the 1980s and 1990s before slowly declining in the 2000s and shrinking in the 2010s. The term "Cantopop" itself was coined in 1978 after "Cantorock", a term first used in 1974. In the 1980s, Cantopop reached its highest glory with fanbase and concerts all over the world, especially in Macau, Mainland China, Taiwan, Singapore, Malaysia, South Korea, and Japan. This was even more obvious with the influx of songs from Hong Kong movies during the time.
