What mountain wears a hat and what is halfway up the mountain?

There is a rainy mountain with a hat, and there is no rain halfway up the mountain. The whole sentence is: "Don't go out in the morning, travel thousands of miles at night, there is a rainy mountain with a hat, and there is no rain halfway up the mountain." This is a weather 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.

"Weather proverbs" refer to the words circulating among the people about forecasting weather changes. For thousands of years, human beings have been trying to make accurate weather forecasts. Weather proverbs are proverbs summed up by working people's oral notes and history, which are used to indicate whether it will be sunny or stormy tomorrow.

Through constant observation and repeated argumentation, weather proverbs are hypothetical, but they can also provide some useful information. Because weather proverbs are obtained through repeated observation and practice, they cannot be said to be unscientific. However, it has regional limitations and may not be universal. Using weather proverbs to make long-term weather forecast is also subject to the subjective limitation of meteorological changes, which is not necessarily feasible.

Because most weather proverbs are not developed on scientific knowledge when they are produced, they lack the scientific spirit of seeking roots. They only describe phenomena without explanation, so there is no theoretical support. However, through continuous practice, weather proverbs are reliable enough to be used in daily life.
