In order to capture the emotional characteristics of the role, I listen to the singer Li's song "Ruthless" on the set every day. The lyrics well reflect the mother's mentality in the film, so the producer added "ruthlessness" to the film, which became an episode of the film. Many actors in the film were moved by the script of the film and volunteered to play. Young-chan Kim, the young actor who plays Cai Zhu in the film, was selected by the crew at a rate of 1%. On the first day of reading the script, Jin Huixiu cried all night. Jin Huixiu happened to see the script of this film. Although she didn't receive an invitation to perform, she liked the story very much, so she took the initiative to contact the producer to ask for a role. Huang Zhengmin's role in the film is less than 10% of the whole film, but in order to increase publicity, the producer specially added his name to the poster, making him feel that he stole the show.
