Many things in the play focus on a little girl, who is an ordinary and mediocre little girl Teng Xiaoxiao. Eager to come to this city. I hope we can be together, enjoy a happy life, have a beautiful love and realize our dreams. The reality is cruel, it will be sad after reading it, but it is hope to see more.
