Characteristics and customs of solar terms in winter solstice

1, the arrival of the winter solstice solar term marks the coming of winter. On this day, although the northern hemisphere received the least solar radiation, it was about 50% less than the southern hemisphere. However, this is not the coldest time, so-called "March 9, April 9 cold." This is because there is atmosphere and water on the surface of the earth, which can store heat, not "save or lose" but "accumulate heat"

Therefore, the weather is usually not very cold before the winter solstice. From winter to the future, although the solar altitude angle gradually increases, it is a slow recovery process, and the heat lost every day is still greater than the heat received, showing a situation of "making ends meet".

3. "March 9, April 9", the accumulated heat is the least, the temperature is the lowest, and the weather is getting colder and colder. If there is the influence of cold air at this time, the weather will be even colder. After this "cold front", the weather will gradually get warmer.

4. Eat jiaozi: It is a tradition to eat jiaozi on holidays in China. This is because jiaozi's homonym is "Jiaozi", which means the younger "jiaozi", and because the winter solstice is the longest day and the shortest night in a year, jiaozi eaten in winter solstice contains the meaning of driving away the cold and cooling down, which means that the whole family is expected to be round and round, and it is auspicious.

5. Give shoes: On the solstice of winter, people will also give shoes to children and children. Generally, the shoes presented are all hand-embroidered. Hand embroidery is different, different for boys and girls. Shoes for boys are generally embroidered with animals, while shoes for girls are generally flowers and birds. Nowadays, embroidery technology is becoming less and less popular, so people will buy it from the market on the solstice in winter, and the patterns are different from before.

6. Brewing: Because winter solstice is the shortest day and the longest night in a year, wine is often favored by people in cold nights, so people often drink and make wine in winter solstice. Today, according to different places, in some places, winter solstice wine-making has become a custom, and it also places people's good wishes for life.
