When is the great cold?

"Slight cold and severe cold, cold without wind", severe cold is the last of the 24 solar terms. When the solar calendar is 65438+1October 20th or 2 1 day and the sun reaches 300, it is a severe cold. "Let Time Test the Weather" is quoted from "Three Rites and Righteousness": "Great cold is the middle, rising above slight cold, so it is called great cold, and extreme cold is called great cold." Great cold means that the weather is extremely cold. Twenty-four solar terms originated in the Yellow River Basin. In BC 104, Deng Ping's taichu calendar officially included the 24 solar terms in the calendar.

The story of the great cold solar terms: It is said that there was a rich boy in ancient times who was ignorant. His family is rich, but he has nothing to do. All I do is eat, drink and be merry every day. After a long time, I ate up all my family's industries. I have no choice but to borrow money from my relatives.

After a long time, all his relatives were borrowed by him. On the first day of the first month of this year, the black sheep wanted to ask his uncle for clothes pawn, but he thought that his uncle had nothing to give except a cotton-padded jacket. He has no courage to ask for more.

In February, the black sheep of his family was still thinking about his uncle's cotton-padded jacket, but his uncle said, "On February 28th, chickens and ducks froze to death." . I still haven't borrowed it.

In March, my uncle sent him away with a sentence of "March 3, freezing to death".

It's April now, and the weather is getting warmer and warmer, so I can't believe what my uncle said, "April 20th, frozen branches".

In May, the black sheep of his family went again, and my uncle replied, "You can't send cold clothes after eating May Zongzi."

It was hot in June, and my uncle threw him another sentence, "People are not caterpillars, but are afraid of the cold north wind in June."

It was very hot in July, and the black sheep found their uncle to borrow a cotton-padded jacket. My uncle said, "I ate dinner in July and half, and let my son go to Dipo Station", which means it's getting cold.

In August, the black sheep of his family visited his uncle again. My uncle said, "On August 15th, the geese opened the door with frost on their heads." It's starting to frost. You can't borrow your coat either.

Every sentence in the short story reveals a solar term with profound implications. Great cold is the last of the 24 solar terms in the whole year. Although the weather is still cold at this time, it is the end of winter. There is a vague feeling of spring.
