When it rains, bloom is colorless, and the moon is occasionally covered by dark clouds.

"It rains when there is no color in bloom, and the bright moon is occasionally covered by dark clouds" is a poem by China, which means that when the flowers are in full bloom when it rains, there are no bright colors in the sun, and the bright moon is occasionally covered by dark clouds. This poem expresses a state in which beautiful things encounter setbacks or limitations, and also implies the impermanence and unpredictability of life.
