Dreams Come True (1960)

Ostensibly a romantic comedy about mistaken identity, this film stars Kitty Ting Hao in two roles, the first as poor flower girl Fangfang and rich relation of a family in Hong Kong, who arrived in Hong Kong to see if she can feel better with the warmer climate. She meets Xihong, played by Kelly Lai Chen, who is the son in the family in Hong Kong. He is, of course, smitten with her, but when the secret is out, will he still feel the same?
