Three seasons in the beginning of winter
The beginning of winter is divided into three periods: first, the water begins to ice; second, the ground begins to freeze; third, the pheasant enters the big water and becomes a mirage.
When water begins to ice, it means that water will gradually freeze from then on, especially in the north;
On the second day, the ground began to freeze. On the fifth day, the temperature dropped to zero, and the surface of the land began to freeze;
The third period 'pheasant entering the water is a mirage', in which pheasant refers to a big bird like pheasant, mirage is a big clam. In the third period, the big birds like pheasant are rare, while the big clam with similar shell and color can be seen on the seashore. So the ancients thought that the pheasant would become a big clam after the beginning of winter.
Beginning of winter and solstice
There are two solar terms that are very important in winter. One is to start winter, and the other is winter solstice. Many friends will confuse the two solar terms of the winter solstice and the beginning of winter. Generally, the beginning of winter is in November and the winter solstice is in December.
Different meanings of time
Beginning of winter
As the first solar term in winter, it begins around November 8 every year when the sun reaches 225 deg. Because of the difference between North and south latitude in China, the real meaning of winter is not based on the "beginning of winter", but on the continuous days when the temperature is lower than 10 ℃. But in the traditional concept of "winter" is "end also", the meaning of end.
After the beginning of winter, the sunshine time will continue to shorten, and the height of the sun will continue to decrease at noon. In China, it is the beginning of winter.
Winter solstice
An important solar term in Chinese lunar calendar, the winter solstice is commonly known as "winter festival", "long to Festival", "sub year old", etc. It is the earliest of the 24 solar terms. On the day of the winter solstice, the sun reaches the southernmost point of the year, almost directly on the Tropic of cancer (23 & deg; 26 \ '). On the day of the winter solstice, the northern hemisphere receives the least sunlight, 50% less than the southern hemisphere. The days in the northern hemisphere are the shortest, and the more northward the days are, the shorter.
Different climate characteristics
China is a vast country with tens of latitudes across from north to south, so there is a temperature difference between North and south. But after the beginning of winter, the temperature difference between the north and the south is even greater. Many places in the north have been dry, withered and cold, while South China is still green, with birds singing and flowers fragrant, warm and pleasant.
The winter solstice is the shortest day of the year. In terms of climate, during the winter solstice, the average temperature in the Northwest Plateau is generally below 0 ℃, and only about 6-8 ℃ in the south. In addition, when the winter solstice begins to count nine, the winter solstice day becomes the first day of counting nine.
