Dear, the four movie prototypes are Sun Haiyang, Peng Gaofeng, Wu Liping and Du Xiaohua.

In this film, Tian Wenjun's 3-year-old son disappeared. Three years later, Tian Wenjun finally got a clue. He was told that he had seen his son in rural Anhui.

When he found his child, his child Pumbaa didn't remember his biological parents very much. He hit Tian Wenjun in the face with his little hand, and Tian Wenjun held Pumbaa's face. Finally, Tian Wenjun held Pumbaa tightly in her arms and burst into tears. Peng Gaofeng, the prototype of the film, is lucky. He traveled all over China, and after three years, he found his children.

In the film, Han Dezhong tells everyone at the welcome banquet of Tian Peng's family that his wife is pregnant and he is sorry for everyone. Because before this, he once said that if you can't find a child, you won't welcome new children. But it was finally defeated by the cruelty of reality.

This passage is also a true portrayal of Sun Haiyang. Five years after losing their children, they have a second child, Sun Hui, who is still looking forward to Sun Zhuo's return. After Sun Hui was born, the whole family was very kind to their children, but Sun Haiyang always felt guilty. He doesn't know what happened to Sun Zhuo.

Before the film was released, Sun Haiyang made the only request that the phone number be printed at the end of the film. Chen Kexin warned that this would be harassed by many malicious calls. Sun Haiyang replied: It doesn't matter, I'm afraid that one day, even liars won't lie to me. This sentence is also used in movies.
