Sean said that the relationship between father and son is not as direct and gentle as the father's love for his daughter. They always love each other clearly, but they have nothing to say together. Sean said that the idea of telling his father's love came from his partner Wang Terry. "When we were doing the late old boys, Lao Wang's father died. His father thought what he did was unreliable, and now he has made achievements, but his father can't see them. Wang Terry said, "I'm sorry I didn't express (my love for him) to my father. Now that my father has passed away, I just hope to see the audience of the movie, and don't leave me with such regrets. "
