Looking back at Mei Yanfang's childhood, her sister has taken her to sell songs to maintain her livelihood since she was four years old, and the two have slept in the same bed when they are performing outside, inseparable. In 1982, her sister submitted the registration form for the rookie competition for Mei Yanfang, but the sister lost the election and her sister won the championship, and the two lives have been different ever since. Mei Yanfang has unlimited scenery in her career, and Mei Aifang has entered the palace of marriage.

Liao Ziyu, who plays her sister Mei Aifang, has two younger sisters in her life, so she can quickly find resonance in the part of the story with her sister. Wang Dani said: "I put the desire to have a sister on Ziyu, she felt it, and directly substituted me for my sister's feelings. On the set, Wang Dani would blurt out Liao Ziyu's sister, and they also practiced songs together during the shooting, and both of them were deeply infected by this sisterhood.
Liao Ziyu, who plays Mei Aifang, is deeply touched by the creative atmosphere of the crew, and she is very grateful to the crew for shooting in the direction of the development of the plot and taking everyone to experience Mei Yanfang's life together. Because of this, she can slowly establish a sisterhood with Wang Dani, who plays Mei Yanfang, from scratch. Mei Aifang said goodbye to her sister before her death, and her emotions fluctuated greatly, and Wang Danni described them as crying until they died and lived: "My feelings with my sister are already very deep and real, and the feeling of being about to lose is really very reluctant. Liao Ziyu, who fully entered the role, and the accumulated emotions with her sister also exploded at this moment. The film presents the legendary life of Mei Yanfang, a generation of divas, and her lifelong feelings with her sister Mei Aifang are a part that cannot be ignored and moved.
