The story takes place somewhere in Guangdong. Sichuan sister Lin Fang (Jiang Qinqin) has been working for ten years. She has formed a strange family with her brother Danian (Zhou Lang) and adopted daughter Xiao Yanzi (Heduo). After hard work, Lin Fang was promoted to deputy director of the workshop of a Hong Kong-funded factory, but was dismissed by the management due to the "work card incident." After losing her job, Lin Fang worked in fast food restaurants and racetracks, fully demonstrating the unyielding character of Sichuan's sister. Her persistence moved the management, and the factory rehired her back as a training coach. Junior high school student Zhang Xiaomei (played by Wen Zhimei) came to Guangdong to join her cousin, but she missed it. She ran into Lin Fang's apprentice Xiao Jian (played by Xiao Longren). Xiao Jian helped her fake identity and apply for a job at the factory. Lin Fang discovered that she was minors and advised her to go home. Unexpectedly, at this time, her little sister suddenly developed leukemia. Lin Fang reported the emergency to the boss, and Boss Huang (played by Li Nuoyi) immediately organized blood tests to save people. Just at this moment, Xiaolan's cousin (Zhang Zheng) appeared.
