After school, Guan Xiaozheng's mother brought him a blind box as a gift. The blind box contained two pairs of shoes, a pair of sports pants, a pair of socks, a sports jacket, and a T-shirt, which his mother thought was a great deal. Guan Xiaozheng was dissatisfied with the colors and styles of the items in the blind box, but his mother felt it was worth it. Later, Little Golden Retriever visited and became obsessed with the dolls in the blind box, even running away from home because she couldn’t get the desired款式. Little Golden Retriever exchanged dolls on forums, and her love for them reached an extreme level, even affecting her daily life. Guan Xiaozheng's mother reminded Little Golden Retriever that the marketing strategy of blind boxes encourages continuous purchasing, making it hard to stop.
