What is the slight cold in solar terms?

1. In daily life, apart from keeping warm, the smell of entering the slight cold year is getting stronger and stronger. People are busy writing Spring Festival couplets, cutting window grilles, going to the market to buy New Year pictures, colored lights, firecrackers, incense and so on, and preparing for the Spring Festival one after another. In terms of diet, mutton hot pot, sugar-fried chestnuts and baked sweet potatoes have become the fashion of Xiaohan. As the saying goes, "three nine make up one winter, and there will be no disease in the coming year", which is the practice of eating mutton to regulate the body in winter. According to "Miscellanies of Jinmen", there was a custom of eating soybean sprouts in Tianjin in the old days. Soybean sprouts are a specialty of Tianjin, made of Chinese cabbage buds. In winter to the future, cut off the stems and leaves of cabbage, leaving only the heart of cabbage, about two inches from the ground, covered with manure, airtight. After half a month, it is crisp and tender, which makes up for the shortage of vegetables in winter.

2. In the cold season in the south, rape should be cleaned and wheat should be topdressing. When encountering strong cold air, sprinkle plant ash, crop straw or cover manure in the field to help the crops survive the coldest season. According to many years' breeding experience, people often speculate on the climate change in the coming year according to the slight cold climate and make a good breeding plan as soon as possible. For example, there is a saying in Shandong that "there is no rain in a slight cold, and there is drought in a big summer" and "if it is cloudy in a slight cold, there will be a spring drought in the coming year".
