After graduating from Rosaryhill School, where many other pop stars had attended, she started working full-time as a model in Hong Kong.

Aside from her musical career, Choi has become a successful actress in the Hong Kong film industry, co-starred alongside famous names such as Andy Lau, Eason Chan, Jay Chou, Mike He, Wu Chun, Nicholas Tse...etc. She wrote an article describing her acting career:

"Earlier before, I have shared with everyone some of my acting experiences. This time, I want to talk about movies. As an artist, whenever I'm working, I have to show the best side and give the best performance to everyone. I have to show the most fit side of me and hence, I'm often in "battling mood". When free, I like to watch slow-pace movies. The too exciting movies I can't stand. I'm the type who can be easily thrown into the world of the movie. Those type of fast-pace movies will end up making me tense and nervous so comedy, romance or humanity issue discussion movies are all more suitable for me."

She has taken Jim Chim Sui-Man (Jim Sir) as a mentor, and is has been in the comedic movie Simply Actors as a kind and comedic porn star. Her breakthrough role in the psychological thriller movie Diary, by the Pang Brothers has earned her many movie award nominations and she received the Best Actress award at the 11th Puchon International Fantastic Film Festival (PIFAN Korean Movie Award).
