Briefly talk about the main contents of the past in the south of the city.

"Old Things in the South of the City" describes a warm and harmonious family living in Ruth in a quadrangle in the south of Beijing in the 1920s. In the late 1920s, a six-year-old girl named Lin lived in a small alley in the south of Beijing. Xiuzhen, a "crazy" woman who often stands in the alley looking for her daughter, is the first friend Eiko makes. Later, Eiko helped her find her daughter, but they all died under the tracks. Eiko also met a young man who was taken away by the police before he knew if he was a good man. Ma Song, the nanny of Eiko's family, also left because of the death of Eiko's father. Later, Eiko's father died of lung disease. Eiko took his family on a long-distance carriage and said goodbye to his childhood with all kinds of doubts.
