What is the saying that it rains on the cold dew festival?

If it rains in the cold and dew season, 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. There are more rainy (snowy) days in winter, which is beneficial to the growth of crops such as winter wheat and rape.

Therefore, farmers don't expect it to rain in the cold dew solar terms, because it indicates that there is less rain in winter and the harvest in the coming year will be affected to some extent. There is also a similar agricultural proverb in Guangxi, that is, cold dew has rain and less winter rain, and cold dew has no rain and more winter rain.

The weather is sunny and cold, with less snow and more spring rain in winter;

This is an agricultural proverb circulating in Hebei Province, which literally means that if it is sunny in a cold and dew solar term, there will be less snow in winter and more rain in spring.

This is the experience summarized by the ancients based on long-term observation, and the accuracy is still relatively high. If the weather is fine on a cold day, some old farmers will start to worry. Because of the abundant snow and little rain and snow in winter, it is not conducive to the growth of winter wheat. Similar agricultural proverbs include cold dew and sunny days, and more spring rain in the coming year.
