Yongyuan is not simply a nostalgia shop but above all a toy store made for children, so that they can establish a strong bond with their past and their memories. It is therefore a place where the children keep their dearest objects, often forgotten over time, which however need to be collected in their memory to bring them back to life once they grow up. The author of this children’s novel poses a fundamental question to us: Once adults, what is it that will make us remember our childhood? And the answer is simple. They are the toys dear to us that take us back to a time and space that made us experience unforgettable emotions.
