It tells the story of Sinan who suffered greatly for six years due to his mother's disappearance, until Qixia's words reignited his hope. Qixia suggested that Sinan directly tell his father that he had seen his mother, which also puzzled Sinan's parents. At a gathering, Qixia revealed the secret that Sinan's father owned two mobile phones and speculated that the other phone was in contact with his mother. She further deduced that her mother was still alive and in contact with her father. Qixia's reasoning was affirmed by Teacher Zuo, who then recounted her experience of being attacked by Yan Ping and forced to hide, as well as her decision to collect evidence to expose Yan Ping's crimes. The entire chapter revolves around the reunion of the Sinan family and the determination of Teacher Zuo to expose Yan Ping's crimes.
