The movie was adapted from the best-selling book "Teacher, Will You Come Back?" written by Wang Zhengzhong, the principal of Shuangwen Junior High School in Zhongliao Township. After the 921 earthquake, Wang Zhengzhong returned to Shuangwen Junior High School where he was doing internship. Seeing the devastated scene, he cried and asked his students, "Teacher, will you come back?" This made him decide to return to the school to teach. He later wrote a book and became one of the leaders of flipped education in Taiwan.
