This article is the first chapter of "Childhood" in the author's novel "Ding Ding Bang Bang Trilogy" (Childhood, Adolescence, and College). The author is purely born in the 1980s. Like most people born in the 1980s, I passed the college entrance examination and entered the city from the countryside. This novel will be written in a semi-autobiographical mode from childhood to graduation from college, trying to show every detail of the growth of those born in the 1980s. I hope it resonates with friends who have had the same experience.
