《汉书·志·五行志下之下》
夜间明亮，所以常见的星皆不见，象征中国衰微。 星陨如雨 ，如，而也，星坠而且有雨，故说 与雨偕也 ，表明雨与星坠，两种灾害互相而成。
夜明，故常见之星皆不见，象中国微也。 星陨如雨 ，如，而也，星陨而且雨，故曰 与雨偕也 ，明雨与星陨，两变相成也。
The night is bright, so common stars are not seen, which symbolizes that China is falling. Falling stars are like rain, in the sense of "as" rather than "and thus". Stars fall with the accompaniment of rain, so it is said "comes after rain", indicating that the two disasters of rain and falling stars are mutually determined.
