When teacher Yu Caili was teaching at the Brigade School, she still persisted in her dream of education and used love and wisdom to illuminate the growth path of children despite family poverty, student bullying and other difficulties. She and her younger brother Yu Bin experienced school violence together, but they always remained optimistic and tenacious. Teacher Yu left the school due to family changes, but he always cared about the children in his heart. Returning to school many years later, she continued to use education to change her destiny, demonstrating the spirit of selfless dedication as a teacher and her persistent pursuit of education.
