A Hearty Response

A Hearty Response is a 1986 Hong Kong romantic comedy and action thriller film directed by Norman Law and starring Chow Yun-fat, Joey Wong and David Lui.
Plot.
Kong-sang is a mainland Chinese girl who illegally entered Hong Kong, hoping to retrieve her birth certificate, which proves that she was actually born in Hong Kong. She flees from her smuggler, Shing (Shum Wai), after she injures him when she was harassed by him.
Meanwhile, police detective Ho Ting-pong (Chow Yun-fat) is an upright and virtuous police officer who was assigned with his partner, Long Man (David Lui), to arrest drug dealer Addict Hung (Ng Hong-sang) in a supermarket. There, Long Man sees Kong-sang stealing from the supermarket and arrests her. As Ting-pong was distracted by this, Addict Hung manages to get on a car and runs over Kong-sang before fleeing.
After regaining consciousness in the hospital, Kong-sang feigns amnesia to avoid being repatriated and identifies Ting-pong as her husband. Since Ting-pong is a man of chivalry, he takes Kong-sang home and takes care of her. Ting-pong's mother (Lee Heung-kam) is really fond of Kong-sang and sees her as an ideal daughter-in-law. However, when Ting-pong's mother convinces him into letting Kong-sang stay, Kong-sang leaves to wander in the streets, not wanting to give Ting-pong a hard time to face his girlfriend. After going through many trials and tribulations, Ting-pong and Kong-sang eventually fall in love. As everything is seemingly going well, Shing reappears and kidnaps Kong-sang.
