In the past (approximately the 50s-60s) Fung Hun Man (Chung King-fai) was a famous writer, producer, and actor in the early days of Hong Kong cinema. During his youth, he adopted two girls and had them become sisters-in-training: Sheung Ying Hung (Liza Wang) and Miu Sing Ho (Gigi Wong). Both girls were groomed into the path of becoming actresses and the two maintained a lifetime rivalry over each other's successes both on and off the stage. At the height of their career, Miu Sing Ho suffered a severe auto accident that affected her ability to walk. Due to her disability, she was unable to continue acting and was forced to retire; she was looked over and Sheung Ying Hung took her place and risen to the top of stardom and became very successful. Distraught, angry, and unable to accept her fate, Miu Sing Ho transferred much of her frustrations over her "sister", Sheung Ying Hung, and blamed her for taking away her success and fame.
