Want to know why it's called nine?

It is called the number nine, because in traditional culture, nine is the extreme number, the "supreme" number and the largest number. The accumulation of "the supreme yang" means that it is gradually decreasing, and it also means that the cold has gone warm, so it is called the number nine.

Jiujiu, also called Jiujiu in winter, is a folk method to calculate the date of warm flowers in spring and cold days in China. Generally, March and April are the coldest time, which is the coldest time of the year.

"Jiujiu Song" summarizes the characteristics of each stage after the winter solstice.

The folk song "99 Songs" says: "If you don't count nine first, you won't do it in 1929. 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. " It's funny, but it correctly summarizes the characteristics of each stage after winter solstice.

The weather is cold from winter to the future. March and September are the coldest times of the year, and spring begins after May and September. These summaries can be found in reality.

Because the ancient heating equipment was not perfect, in the long cold winter, everyone invented this way of counting nine. As soon as the "September 9th" is over, winter will pass, and it seems that this originally difficult winter will become less long.
