What does the Great Cold stand for?

The cold represents the end of four o'clock and also indicates the beginning of a new year. After the severe cold, beginning of spring will usher in a new year's solar cycle. The Great Cold is the last of the 24 solar terms, which falls from 65438+1October 20th to 22nd every year. Although the great cold is cold, it is near spring, and it will not be as cold as the heavy snow from winter to day. At this time, people are busy removing old decorations, pickling new year's dishes, preparing new year's goods and various sacrificial supplies, cleaning dust and cleaning things, because the Spring Festival is coming.

Three stages of severe cold: the first stage of chicken milk: chickens are wooden animals, sensing spring in advance and starting to hatch chickens. Secondary syndrome bird disease: birds such as eagles are in a state of strong predation ability, hovering in the air to find food to supplement energy to resist the cold. The third time, the water is moist and the abdomen is solid: it is completely frozen from top to bottom and extremely cold. According to the principle that extremes meet, spring water is born in the depths of hard ice and will begin to melt when it is extremely frozen. "The History of the Song Dynasty, Taishou Benji II" records: "Call the capital to be a high-aged silk, and the centenarians will be given a gold belt. This is a rainy and snowy day, and then I will give thousands of dollars and rice charcoal to the elderly and the poor. " In the rainy and snowy solar term of "send warm", Song Taizong's actions touched the lonely old people and poor people in Beijing, and the idiom "timely help in the snow" came from this cold allusion.
