Have you ever thought is there a wonderland in some unknown places? And what does it look like? It may differ from person to person. A magnificent castle stands in the valley, surrounded by mountains and murmuring streams. The climate here is very mild, suitable for the survival of most organisms, and birds can often be seen flying by in the sky. During the day, the sun shines brightly, and at night, the sky is filled with stars. This does not belong to any planet. What does the fairyland look like in your heart?
