In the mid-1990s, Li Niuniu's family had a big accident around the time of the college entrance examination, and her fate took a turn. Due to family conflicts, Li Niuniu's third sister ran away from home, causing her younger brother to be paralyzed in bed. Her father, who was under too much pressure, died in a car accident while out, and her grandmother was critically ill and hospitalized. A series of disasters brought the life of this family of seven with three surnames to a low point. At this time, Li Niuniu resolutely decided to give up her studies and help her mother support the Zhang family. She took care of her paralyzed younger brother and her long-term ill grandmother, and took on the responsibility of the entire family. For eight years, Li Niuniu's efforts helped her younger brother recover and get into college. In order to repay his teacher's kindness, Song Chao selflessly dedicated himself to the Zhang family and finally married Niuniu. The third sister was unruly and very willful, bringing many disasters to the family, but Niuniu still stayed with her. When the third sister was suffering from leukemia, she donated bone marrow to her, and finally moved the third sister, making her realize the importance of family affection. Li Niuniu went from running a small restaurant to being in charge of a large business group. She was self-reliant and strong, and with the help of her family, she eventually achieved success in her career.
