It rains in winter in the north

"When it rains in the cold open air, there will be less rain in winter, and when it doesn't rain in the cold open air, there will be more rain in winter." This is an agricultural proverb, which predicts the winter rainfall through the weather conditions on the day of the cold dew solar term. The literal meaning is also relatively simple, saying that if it rains in the cold and dew solar terms, there will be less rain (snow) in winter. On the contrary, if the weather is sunny in the cold and dew solar terms, there will be more rain (snow) in winter.

Rainy (snowy) days in winter are conducive to the growth of crops such as winter wheat and rape, so farmers don't expect it to rain in the cold dew solar term. Because this indicates that there is little rain in winter, the harvest in the coming year will be affected to some extent. In Guangxi, there is a similar agricultural proverb, "There is little rain in winter, and it doesn't rain in winter."
