"비" is the Korean word for "rain." It refers to the precipitation that falls from clouds in the form of water droplets. Rain is an essential part of the Earth's water cycle, helping to nourish plants, replenish water sources, and maintain ecosystems. In South Korea, the rainy season, known as 장마 (jangma), typically occurs in summer, bringing heavy rainfall. This season is crucial for agriculture, as it provides the necessary water for crops. However, excessive rain can also lead to flooding and other natural disasters, highlighting the importance of balanced precipitation.
