Anson's ninth ancient poem

Counting Nine Songs is not an ancient poem, but a folk song of China. It refers to the law that the weather in various regions changes according to time after the winter solstice. From winter to Sunday, the first nine days are 19, and the last nine days are 29, counting backwards until 998 1 days later, and the winter is over.

The content of Jiujiu songs in each region is different. The content of the northern Jiujiu song is: 1929, don't shoot, walk on the ice in 3949, watch the willows along the river in 5969, open the glaciers in 79, return to the geese in 89, and add 19 in 99 to plow cattle everywhere.

The content of Hunan No.9 song is 1929, hands in your arms, 3927, no rain dripping in front of the eaves, 4936, plastic candles in front of the eaves, 594 15, annual drums played by every household, 6954, spring breeze, 796 13, and pedestrians put their clothes on.

Generally speaking, this means that when you start counting to nine, the weather is already very cold, because counting to nine starts on the winter solstice. There is a folk proverb in China, "The ninth day is warm, and the second day is cold". It was warm at first, and then it was particularly cold all winter. There is a saying that "the first day is not greedy and the ninth day is warm, and the continuous rain and snow lead to winter disability."
