Carina Lau moved to Hong Kong with her family at the age of 14 and at the the time could not speak the local Cantonese and was often teased by other people the "Mainland Girl". Carina Lau would eventually gave her best effort to learn the language and then was re-accepted at the TVB actors training program when she had improved her speaking ability. It was 1983 the year when she had graduated from the program and launched her acting career as contract basic actress for TVB, and her now boyfriend Tony Leung(Happy Together) was graduated one year ealrier.
Her acting career for TVB was limited to playing ornamental parts in series for the first several years and she didn't get a major challenging starring role until the hit series Looking Back in Anger. That series had established her status as a strong leading lady, but Carina Lau was aiming to abandon the small screen for films. Carina Lau had been in tabnoid headlines for her near-marriage romance with a handsome billionaire in the late 80s, and Carina Lau was considering giving up acting to marry him but the wedding got cancelled the last minute, and Carina was devastated. Shortly after she started dating Tony after partnering to do a stage play called "Happy Lemon Husband".
It was I am Sorry (a low-budget dramedy) that first garnered her the HK best actress nomination in 1989, and she had previously been sent out by TVB to do some films but nothing significant enough to turn her into a film star. Since leaving TVB, Carina Lau had been approached by film jobs consistently. Carina Lau found the dream role when Wong Kar Wai let her play a sexy and volatile showgirl in Days of Being Wild opposite Leslie Cheung and Maggie Cheung, and she was in the spotlight and became the "It" girl of the year during film festivals and awards. Carina Lau once told the press that it was WKW who taught her how to bring out the best of her acting skills and how to use body language to convey emotions.
