Poetry about the weather: {} No rain, no waist?

A rainy mountain is wearing a hat. Rainy mountains have no waist.

This is a meteorological proverb, which means that the cloud is on the top of the mountain, covering the top of the mountain, like wearing a hat, it's going to rain; Clouds are halfway up the mountain, and the mountainside can't see the sun. Refers to the positional relationship between mountains and clouds. It's going to rain, and there are clouds on the top of the mountain, such as "wearing a hat"; When the clouds cross the hillside, it won't rain.
