This book is adapted from my own life experience with a little fantasy. I suffered a lot since I was a child and was born a mentally retarded child. When I was in junior high school, I wrote letters and made friends with Liao Fudi, a female classmate in the yellow class. In the end, we became close friends. I received the support of my head teacher during my three years in junior high school. Working as a cadre, managing discipline in dormitories and classes, from timidity to boldness, and then joining the army in 2008. I never thought about being a special soldier, nor did I think I would fall in love with three female college students, but I loved the girl named Li Xiaoli even more. I was left alone in Huibaochang, waiting for them to come back to pick me up. I waited for a long time, but they didn't come back. After waiting outside the factory for a long time, I still didn't come back. I left Huibaochang sadly and bitterly, and I never went back since then, never again.
