What is the reason why it doesn't rain in Chongyang and it is dry in winter?

The reasoning of this proverb is as follows:

It is a folk agricultural proverb in China that there is no rain in Chongyang and there is no rain in winter. It predicts the rainfall throughout the winter by observing the weather conditions of the Double Ninth Festival and the thirteenth month of the lunar calendar. The reasoning process of this agricultural proverb is as follows: The Double Ninth Festival is the ninth day of the ninth lunar month, which is considered as an important festival in autumn. Many places have the custom of climbing mountains and enjoying chrysanthemums on the Double Ninth Festival. The thirteenth day of the lunar calendar is the fourth day after the Double Ninth Festival.

According to the farmer's proverb, if it doesn't rain on the Double Ninth Festival, it won't rain in the following 13th lunar month. If it doesn't rain on the thirteenth day of the lunar calendar, it usually means that there will be less rain in the whole winter, which may cause drought.

This reasoning is based on the climate characteristics of most parts of China: autumn is a rainy season, while winter is usually dry. Therefore, if it doesn't rain on the Double Ninth Festival and the thirteenth day of the lunar calendar, the probability of rain in winter will be reduced, which may lead to drought. This reasoning is not absolute. Climate change and other factors may also affect rainfall, so we can't rely entirely on this agricultural proverb to predict the weather. It is only a reference method based on experience summary, which has a certain guiding role for farmers to arrange agricultural production.
