It's September weather now.

The meaning of Jiujiu: Jiujiu, also known as Winter Jiujiu, is a folk solar term in China. The number 9 starts at the end of the solstice in the early winter of the Gregorian calendar 65438+ every year. Count nine cold days, that is, from the solstice of winter, count a "nine" every nine days until the "99" of 81 days, and the weather will warm up. In fact, it is "99-99, plowing cattle everywhere"-90 days, which is 9 days.

Why count to nine? Why count "nine"? Why not count two, three, four, five, six, seven and eight? This is different from the ups and downs of Yin and Yang in China's traditional philosophy, that is, warm coming and cold going.

Nine is the number of "Zhiyang", also called Lao Yang, and nine is the largest number. The accumulation of "Zhiyang" means that Yin Qi is decreasing day by day, and it is tired to the end for nine times, which means that the cold is getting warmer and "the spring is deep".

Count nine songs:

The' 99 Disaster Relief Song, commonly known as' 99 Song', which is widely circulated in China, vividly records the climate and phenological changes between the winter solstice and the vernal equinox, and also expresses some laws of farming activities. The widely circulated "1999 Song of Eliminating Cold" said:

"1929 don't push, you can walk on the ice in 3949, see the willows by the river in May and June, the river freezes in July and September, and swallows come in August and September.

99 plus 19, plowing cattle everywhere. "
