Xiaohan is the twenty-third of the twenty-four solar terms and the fifth solar term in winter. Every year on January 5 or 6, when the sun reaches 285 degrees of yellow longitude, it is a small cold. During the cold season, most parts of the continent have a cold climate, and the weather changes during this time have an important impact on people's lives and agriculture. The ancients said: "The most afraid of the cold is a sunny day", this sentence expresses the omen of sunny weather in the cold season and its possible impact.
In the agricultural proverb, "the little cold is warm and the snow is coming" is a common expression, which means that if the day of the small cold is sunny and warm, then there may be cold weather after the beginning of spring, and even snow. This expression is based on observations and summaries of experience on the climate. Xiaohan and Dahan are the coldest solar terms in winter, and if Xiaohan is sunny and warm on this day, then it may indicate that the next winter climate will be relatively stable and not too cold. However, if it is rainy or cold on this day, it may indicate that the winter will continue to be cold, and there may even be extreme weather such as snowstorms.
However, if it is rainy or cold on this day, then this may be a sign that the winter will continue to be cold, and there may even be extreme weather such as a blizzard. This weather condition is detrimental to the growth and development of crops, as low temperatures can slow or stop crop growth, while blizzards can cause mechanical damage or frost damage.
In addition, there is a saying in the agricultural proverb that "if there is no rain in the small cold, there will be drought in the small summer", which means that if there is no rain on the day of the small cold, then drought is likely to occur when the summer summer season comes. This is because Xiaohan and Xiaoxia are separated by a long time, but their climatic characteristics are related to a certain extent. In a slightly cold and sunny year, summers tend to be prone to drought, which can adversely affect crop growth.
People usually pay attention to the weather conditions on this day and predict future climate change based on agricultural proverbs. While these predictions are not 100% accurate, they reflect concerns and concerns about climate change to some extent. At the same time, these agricultural proverbs are also an important embodiment of meteorological and agricultural knowledge in traditional Chinese culture.
