How do you count to nine? Will it get cold after the solstice in winter?

"1929 didn't shoot, walked on the ice in 3949, watched the willows in 5969, opened the river in 79, brought geese in 89, and added 19 in 99, plowing cattle everywhere." It gets cold after the winter solstice.

The "ninth" winter solstice also means entering the coldest "ninth" cold weather in a year. Ancient ancestors believed that from the winter solstice, every few nine days counted as a "nine" and nine "nine", and after 8 1 day, spring came naturally.

The Yijing takes yang as nine, which is actually a process of strengthening yang. By May 9th, the flying dragon was in the sky, the day was flourishing and the weather was warm. Before the arrival of the winter solstice, the ancients drew a "map of the cold in 1999": from the winter solstice, a plum blossom was painted on the window. When a beautiful woman gets up early and dresses, she draws a circle with rouge every day. When 99-8 1 is complete, the plum blossom turns into apricot blossom, and the window is full of spring scenery.

Working people have experienced thousands of years of struggle against the severe cold of snow and wind, and based on their long-term practical experience, they have created many "Jiujiu Songs" describing the changes of temperature and humidity during the "Jiujiu" period. For example, the 99 folk song popular in the north: Count to nine and then count to nine, 1929 Don't shoot. Three, nine, four, nine, walking on the ice. Look at the willows by the river. Seven or nine rivers open and eight or nine swallows come. Ninety-nine and nineteen, plowing cattle everywhere.
