I believe that many people have played the game of printing fingerprints on the ice flowers on the windows when they were young. This article uses this point to cleverly let five children travel through the world of ice flowers to experience the childhood of adults, and to contrast the childhood of children now with the childhood of children in the past. It also uses the reflection of ice flowers to introduce the eighty-eight constellations in the sky, imagine the Big Dipper as seven older wise men, imagine the ice flowers as a city of dreams, and the word "Fu" as a maze and a tomb of dreams. Let five children experience all this together, giving today's children a different childhood experience.
