Which of the 24 solar terms is beginning of winter? It is determined on the basis that the sun reaches 225 degrees of the yellow meridian.

1, beginning of winter is the nineteenth of the twenty-four solar terms in the lunar calendar, which was determined on the basis that the sun reached 225 degrees of the yellow meridian. Beginning of winter is not only a time to hold a grand harvest festival and a harvest feast, but also a season of cold wind. At this time, in the north, it is the winter months when the water freezes and the ground begins to freeze, but in the south, it is the weather of Xiaoyangchun.

2. After beginning of winter, it means that winter has officially arrived. Vegetation withers, stingers sleep, and all activities tend to stop. Although there is no such thing as hibernation, there is a custom in China that beginning of winter makes up for winter. Protein, fat and carbohydrates are called thermogenic nutrients. Therefore, the intake of staple food and oil should be appropriately increased in winter to ensure the supply of high-quality protein.
