Dongdong is an autistic child who is very good at imitating what he hears. However, there is one mystery the music teacher cannot figure out: since Dongdong is so good at imitation, why can't he imitate her telling musical stories instead of scolding the children?冬冬是個自閉兒，很會模仿聽到的話，但是音樂老師還是無法接受，既然冬冬這麼會模仿，為何只模仿她罵人，就是不會模仿她說的音樂故事呢？
