A Patch of Love (1968)

Kit-Fong was cultivated by composer Chun-Fai, who even invited her to perform in nightclubs. Kit-Fong's mother died of illness, and Chun-Fai sold her piano to help her tide over the difficulties. Kit-Fong couldn't bear it, so she borrowed money from the nightclub manager to buy a piano back, but she was almost cheated. Chun-Fai was so moved that he decided to marry Kit-Fong. Chun-Fai asks his brother for the money left to him by his father, but he wants to embezzle the inheritance, so he forces Kit-Fong to leave Chun-Fai, who has no choice but to go abroad. Chun-Fai always drank to drown his sorrows. Fortunately, he was encouraged by his friend and his sister Pik-Shan, who became famous in one song. Shan is very loyal to Fai, but unfortunately she is terminally ill. Fai marries Shan to repay her kindness. Fong returns and learns that Fai is married. While sad, Shan is missing and brings Fai and Fang together to renew their relationship.
