Who does this gift falling from the sky belong to? Get or give? It is an important question in life! Own or share? It is an important subject in life! A strange and imaginative picture book, allowing children to learn the principles of interpersonal relationships and understand the principles of happiness in life. One Thursday, "it" fell from the sky! None of the insects knew where this treasure came from or what it was. The spider said that this magical treasure was his, and he built a magic city to display the treasure, but other insects had to pay a leaf to get it.
