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 Eiko's first friend. Xiuzhen once had a crush on a college student. Later, college students were taken away by the police, and Xiuzhen's daughter, Xiao Guizi, was left at the foot of the city by her family. Life and death are unknown. Eiko is very sympathetic to her. Eiko learned that the little girl's life is very similar to that of the little devil, found the mark on the back of her neck, and quickly took her to Xiuzhen. Xiuzhen knew her daughter who had been separated for six years, and immediately took her to find her father. As a result, the mother and daughter died tragically under the train wheels. Houjia moved to Xinlian Hutong. Eiko met a young man in an abandoned garden nearby. In order to pay for his brother's education, he had to steal. Eiko thinks she is kind, but she can't tell whether she is a good person or a bad person. Soon, the police took the young man away, and Eiko was very sad. When Eiko was nine years old, Feng Daming, the husband of her wet nurse Ma Song, came to the Lins. Eiko was very sad to learn that Ma Song's son fell into the river and drowned two years ago, and her daughter was sold to someone else by her husband. She couldn't understand why Ma Song left her children to wait on others. Later, Eiko's father died of lung disease. Ma Song was also picked up by her husband with a little donkey. Eiko took his family on a long-distance carriage and said goodbye to his childhood with all kinds of doubts.
