In the process, Ham is reunited with her long-lost twin sister Katherine, Chow's daughter. Since losing her mother whose health took a turn for the worse after Chow's marriage to Julie, Ham has undertaken a chivalrous course in the footsteps of her aunt. She thwarts the scam marriage set up by Fung for Katherine and his idle son, using the servant Chu Yat-keung as bait, and exposes Fung's illicit affair with Julie. Crossing boundaries of class and wealth, the servant Chu and Katherine become man and wife. A happy Ham leaves, continuing to devote her life to the causes of social justice.
Music
Director Wong Yiu, recognising the spending power of a new demographic, was looking to create a teenage sensation for the factory girls. It soon became a social phenomenon in the 1960s. Former child star Connie Chan Po-chu fitted the bill perfectly with her doe-eyed innocence framed by silky long hair. In Girls are Flowers, she plays a young tutor falling in love with a handsome boy. However, their road to romance is paved with potholes and speed bumps. Chan's fellow former child star Nancy Sit plays the boy's younger sister who saves the day with her shrewd, nimble-minded plans. Sit's role may be small but with radiance from her glorious smile and beaming personality, she brightens up this musical romantic comedy like a fairy-tale nymph.
