In a Beijing Hutong in 1983, 16-year-old Su Zhenyue stood under the 17th locust tree at the base of the red wall, clutching the tin biscuit box left by her mother. Hidden in the box was half a yellowed photo - a man wearing a good-quality shirt holding a baby, with the foundation of the China World Trade Center under construction behind him. The neighbor said that this was the father she had never met, but Aunt Wang from the neighborhood committee always said when hanging the quilt: "That man has already followed Nanmanzi, don't wait any longer."
In order to raise medical expenses for her seriously ill grandma, Su Zhenyue set up a shoe repair stall in the night market without telling everyone. Before the pony stall in front of the stall was warm, he was kicked over by a young man in overalls - it was Gu Yanzhi who lived at the end of the alley. His father was a contractor on the construction site, and he always felt that she, a "fatherless girl", was blocking his way.
