This volume is short, the language is simple and fluent, and it tells the naughty story of "I" (Zhu Duoxing) and cousin Xiaosha in a first-person perspective. Zhu Duoxing and his cousin Xiaosha are in the same class, and they are messing around all the time. But Xiaosha has really bad luck, because his name sounds like "Xiaosha", which means "little dumb". Unlike the usual stories of little troublemakers, these stories are told from the standpoint of troublemakers. For example, watering the flowers and grass downstairs with a shower nozzel, and spray graffiti on the walls, etc. When female writer writes a boy story, you can feel how the boys are both naughty and dashing at the same time, which fully demonstrated the writer's solid writing skill. You will read the reason for every trick or trouble they make. Looking at the world of adults from the child's perspective, it is hard to tell if the child is ridiculous or the other way around. According to Qin Wenjun, many of the stories of these two little troublemakers evolved from the actions of her two younger brothers. Those are some remarkable naughty days, full of fun and innocence.
