Samuel Hui Samuel Hui Kwun-kit (born 6 September 1948), 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.
Chầu văn Hát chầu văn (] ), or in secular form hát văn, is a traditional folk art of northern Vietnam which combines trance singing and dancing. Its music and poetry are combined with a variety of instruments, rhythms, pauses, and tempos. Hát chầu văn originated in the 16th century and spread quickly. The main musical instrument used in hat van performance is the dan nguyet or moon-shaped lute. The genre is famous for its use in rituals for deity mediumship. Chau Van serves two purposes: to help hypnotize the medium for reception of the deities and to accompany the medium's actions with appropriate music.
