Early years In 2000, Chung was contacted by one of the model agencies she worked part-time with when she was in Hong Kong. She was offered a job opportunity by
Emperor Entertainment Group (EEG), which she accepted in that year. She became a contracted artist and underwent training before making her debut. She was advised by her manager Mani Fok to adopt the "Chung Yan-tung" () as her stage name, after consulting fortune tellers. The name was supposed to enhance her business skills.
Acting debut Chung made her acting film début in
U Man (2002). She appeared in a number of films such as
Beyond Our Ken (2004), which earned her critical acclaim as well as a nomination for Best Actress in the
Golden Bauhinia Awards. In
Beyond Our Ken, Chung played Chan Wai-ching, a spurned girlfriend of the eponymous Ken. The film had its world premiere at the
Tokyo International Film Festival and grossed HK$3,886,355 at the box office. In January 2006, the film
49 Days that Chung starred in had exceeded the HK$10 million (US$1.28 million) mark, earning a spot in one of Hong Kong's best box office films for that year.
Return to film industry After withdrawing from public for more than a year following the
Edison Chen photo scandal incident and later confessed to having contemplated suicide, Chung apologised for hurting those around her, especially her long-time bandmate
Charlene Choi. During the hiatus, she took classes in many areas, such as kung fu (
Wing Chun), gymnastics, singing, dancing and acting, which she hoped would serve her professionally. In July 2009, it was disclosed that she would get a 7-figure sum for the endorsement of
botox treatment clinic Dr. Pro. Chung also appeared on stage in an adaptation of
Neil Simon's
I Ought to Be in Pictures, produced by Emperor Concerts, part of EEG, for a budget of HK$2 million. The silent video, previously filmed in Hong Kong, was shown at the fair lasting 8 minutes and 43 seconds. The video showed Chung switching from laughing to crying. This attraction drew hundreds of visitors each day. Many audiences thought that Chung used the art expression to reveal her apologetic attitude. However the video was only meant to show how attitudes are expressed through art, according to artist and video creator Jiang Zhi.
Debut solo album On 27 March 2010, Chung released her début solo EP, which was sold as part of the package of Twins' fourth compilation album
Everyone Bounce (人人彈起). The EP includes six songs, including début solo single
More Hearts (心多) that was released a year prior to the album release.
Sisters Who Make Waves On 5 August 2022, Chung debuted at 5th place for the third season of
Sisters Who Make Waves which premiered on 20 May 2022, on
Mango TV. Chung decided to join the competition with her long time bandmate
Charlene Choi and compete against other 28 female artistes with diverse talents. At the same time, Chung aimed to lose weight and retuning her mindset. Due to 4 months of rigorous dance rehearsals and sheer willpower, Chung succeeded in shedding 20 pounds at the end of the competition. ==Personal life==
