Joey Yung (Chinese: Rong Zu Er ; Jyutping: Jung4 Zo2 Ji4; born 16 June 1980) is a Hong Kong singer and actress signed to Emperor Entertainment Group.
In 2004, Yung released her the studio album Nin9 2 5ive and her first photo album The Real Joey, Glamour in London. The photo album was well received by the public and sold out shortly after its release. Her second album in 2004, Give Love a Break, was also a commercial success, breaking the platinum mark with pre-orders alone. At the end of the year, Yung released a Cantonese cover of "Chihuahua" (a song previously released in English by DJ BoBo) as part of a Coca-Cola advertising campaign in Hong Kong. At the year-end music awards, she won over 20 awards and received the highest honour award again, the Media Award. It was estimated that for 2004, her income was HK$60 million, including her income from endorsements alone amounting to HK$10 million. In 2005, Yung released her third compilation album, Love Joey 3, as well as a new Cantonese studio album, Bi-Heart. Her fourth major concert, Reflection of Joey's Live Concert, spanned eight days in October and November. The concert's theme song, "Hao Shi Duo Wei ", was mixed and re-arranged in South Korea, resulting in the "Hao Shi Duo Wei  Reflection Mix". EEG was sponsored by Sony Ericsson for the theme song's music video. Following the success of the concert, its CD/VCD/DVD was certified triple platinum, selling 120,000 copies, and Yung's album sales surpassed five million worldwide, an impressive feat in the Cantopop industry (in which an average album will sell around 100,000 copies). However, Yung suffered from strained vocal cords and had to work for several days without talking in an effort to relax her vocal cords. She also spent several days receiving remedial acupuncture treatment in Nanjing, and took singing lessons under vocal coach Christine Samson, known for teaching corrective singing techniques to many Cantopop singers. That year, she purchased two connecting flats named "The Legend" at Jardine's Lookout, Hong Kong, for HK$40 million. On 27 February 2006, Yung released her tenth Cantonese studio album, Ten Most Wanted. According to Yung, the album was more experimental and had higher production values than her previous albums. She worked with Mavis Fan for two songs on the album; "Get Fit with Jane Fonda" and "Torn Tongue", both of which had lyrics by Yiu Fai Chow. On 21 July, she released a Mandarin album, Jump Up - 9492.
