Beginning of winter custom: eat jiaozi, brew yellow wine and eat raw onions.

1, eat jiaozi

In northern China, there is a custom of eating jiaozi in beginning of winter. In order to improve your life in early winter, jiaozi is delicious, but it is not in jiaozi. In the north, it is the custom to eat jiaozi in winter, because jiaozi looks like ears. People think that if you eat them, your ears won't catch a cold in winter.

Step 2 brew yellow rice wine

It is a traditional Shaoxing wine-making custom to start brewing yellow wine in beginning of winter that day. The low water cooling temperature in winter can effectively inhibit the growth of miscellaneous bacteria and make the wine form a good flavor in the process of low temperature and long-term fermentation. This is the most suitable season for wine fermentation.

Step 3 eat raw onions

There is a proverb in Nanjing: "An onion and a half a day brings wind to your legs in winter." When they arrived in beginning of winter, the old Nanjing people paid special attention to eating raw onions to resist the cold and wet winter in Nanjing and reduce the incidence of diseases.

Meteorological changes in early winter

In early winter, the sun has reached the longitude of 225 degrees, the sunshine time will continue to be shortened, the height of the sun will continue to decrease at noon, and the amount of solar radiation obtained by the northern hemisphere will be less and less, but there is still some energy due to the heat stored on the surface in the second half of this year. Because there is still "accumulated heat" on the surface, it is usually not very cold in early winter, and the real cold is after the winter solstice.

Due to the large span between north and south in China and the great climate difference between north and south, the winter with this climatic significance is obviously late for some parts of China. After winter, the climate changes from dry autumn to rainy and cold winter. In the southern region, from beginning of winter to Xiaoxue, sunny, warm and comfortable "Xiaoyangchun" weather often appears, and there is a folk saying that it is "Xiaoyangchun in October".
