In our childhood, everyone has more or less a "friend" to accompany their growth - a doll. This is a existence that brings us endless joy and comfort, makes us no longer afraid in the lonely night, and becomes our most intimate friend. However, as we grow older, it gradually fades from our lives and becomes a cloud of dust at the bottom of the box. But dolls are not just toys for children. It is the witness of our childhood and the sustenance of our homesickness. Every eye that does not fade, every slightly worn smile, carries the innocent self that we used to be. They remind us of those carefree days and remind us not to forget who we really were. The doll is not only that, it is also a carrier of culture. From Chinese clay sculptures, to Japanese wood carvings, to western muppets, each kind of doll carries its own cultural background and representative characteristics. They use silent language to tell a story full of vivid life color. Through these dolls, we learn about the world, we connect emotions, and we preserve memories. Don't leave those dolls in the corner, and don't let them just fade in your memory. Take them out, think about that childhood self again, think about those beautiful moments - using the doll to find the most authentic self. After all, dolls are not only children's companions, but also the sustenance of our homesickness.
