Han Xiao's statement guides agriculture.

As one of the 24 solar terms in China, slight cold contains many traditional customs and cultures. In folk parlance, slight cold weather is not very cold, but in fact, slight cold weather is very cold and severe. Over time, it is also the main function and role of slight cold to start counting to nine and prepare for the winter.

Xiaohan agriculture

In the slight cold season, everything starts to get cold. When the weather is cold, crop seeds need protection. We should continue to do a good job in cultivating spring flowers, do a good job in preventing freezing and moisture, and strive for a bumper harvest of spring flowers. In order to prevent snow and freezing rain from breaking fruit trees in bamboo forests, it is foggy and windy in winter, so special attention should be paid to safety in fishing and breeding operations at sea or in rivers and lakes. From the snowfall in winter, we can infer the scene of 2008. The northwest monsoon from Eurasia prevails in winter in China, with less water vapor content and less precipitation. This kind of rainfall needs more attention, so as to ensure next year's harvest.

Buy new year goods in the twelfth lunar month

Slight cold is the coldest solar term. When there is light snow, the river is basically closed. People can go skating and play with snow. People can go out to have snowball fights and make snowmen. There is Laba Festival in the twelfth lunar month, so it is popular to eat Laba porridge. At this time, seasonal foods include baked sweet potatoes and sugar-fried chestnuts, and there are more sugar-coated haws on the street; After the twelfth lunar month, people began to buy new year's goods. In the countryside, people go to the market to buy red paper, New Year pictures, firecrackers, candy, colored lights and so on. In order to welcome the Spring Festival, women prepare paper-cuts at home. Under such circumstances, we can clearly see the slight cold atmosphere of the New Year.

Twenty-four solar terms agricultural songs

In the agricultural songs of the 24 solar terms, he said to Han Xiao: "Han Xiao entered the 39 th, became rich for the New Year, and constantly summed up new experiences in winter." Because there is heavy snow at any time in the slight cold, "the snow becomes a river and the wheat is thin", which will frostbite or freeze the wheat to death. In this season, people can increase cold-proof and warm-keeping facilities to ensure the safety of crops and livestock in winter. Seasonal changes can not only guide crops, but also predict future temperatures.
