When did you start counting to nine?

The count of nine starts from the solstice of winter, when jiaozi is to be eaten, and the children are helping their parents pack jiaozi.

The winter solstice is the 22nd solar term in the "24 solar terms", and the solar calendar reaches 270 degrees. Every year, the festival is held on 65438+February 2 1-23 in the Gregorian calendar. The solstice in winter is the extreme point of direct sunlight spreading to the south. From winter to the sun, the sun shines directly on the Tropic of Capricorn, and the sun is most inclined to the northern hemisphere, and the solar altitude angle is the smallest. In all parts of the northern hemisphere, the days are the shortest and the nights are the longest.

Folk songs:

"99" is the product of farming society, with a long history, which has been passed down from mouth to mouth among the people.

It is a summary of the experience of ancient people in production and life practice from generation to generation, using some ecological reflections and meteorological signs in nature. It is quite scientific and still plays a guiding role in the arrangement of people's production and life, so it has been popular and widely circulated in people's mouths and reflected in people's behavior.

China folk widely circulated "99-year-old songs to relieve cold", commonly known as "99-year-old songs". There are many versions of 99 ballads. Version examples: 1929 did not shoot, walked on the ice in 3949, watched willows along the river in 5969, opened the river in 79, swallowed it in 89, and added 19 in 99, plowing cattle everywhere.
