The first sentence of the poem "Woods in the rain" says that the Woods in the rain are a fairy tale world. Why?

Woods in the rain \ r \ nAuthor: Jin Bo \ r \ nWoods in the rain are a fairy tale world \ r \ nWalk in and you will become an elf. \ r \ nEvery tree will give you a lot of joy. \ r \ nYou will also find many new things. \ r \ nThe crystal beads of rain rolled down on the leaves, \ r \ nThe spider spun silk to string a necklace for you, \ r \ nThe carpet paved with fallen flowers was soft and fragrant, and \ r \ nFrogs played drums and danced for you. \ r \ nBirds are willing to sing in the rain.
