Rain refers to water droplets or ice crystals falling from the clouds, which is a common form of precipitation in nature. Rain is usually formed by the sublimation of water vapor in the atmosphere into clouds, then condensed into water droplets or ice crystals in the clouds, and finally fell to the ground to provide water for nature and human beings. Rain also symbolizes freshness and cleanliness, and is often compared to "water in the sky and oil in the earth", which often appears in literature and art.
