A piece of historical information about September 19.

From the solstice of winter, nine days is one nine days!

"Jiujiu", also known as "Winter Jiujiu", is a folk solar term in winter in China. This "number nine" comes from the second "winter solstice" at the end of 65438 and the beginning of February in the solar calendar every year.

The day began.

There are many customs of "counting nine", among which "Jiujiu Song" is the most extensive and has a long history. These songs skillfully use the phenological phenomena in nature and vividly reflect the laws of weather changes during the Ninth Five-Year Plan period. As far as most parts of China are concerned, the weather was not the coldest in the past 29 days, but "1929, I can't reach it." At the end of April 9, it was almost the "great cold" solar term, so "on March 9, 49, the bitch froze to death." After May 9, the earth gradually rejuvenated and the weather gradually warmed from cold, so "May 969, look at the willows by the river; 7989, walking alone. " By 1999, it was already a "shock pad" solar term, so "the thunder of 1999 made a lasting noise."

China generally has temperate zone, warm temperate zone, subtropical zone and marginal tropical climate zone from north to south, and the climate change, phenology and people's living habits are different from place to place. Although the "99 songs" in different places have the same trend from cold to warm, their descriptions have their own characteristics. Here are some songs: ◆ Middle and lower reaches of the Yellow River: "1929, no shooting, walking on the ice (on the river) in 3949, watching willows along the river in 5969, opening the river in 799, taking geese in 899, and plowing cattle everywhere in 999 199." ◆ Jiangsu area: "I didn't meet each other in the first nine nine twenty-nine, I shivered in the cold in the third nine forty-nine, I danced in the streets of poor Han people in the fifth nine forty-five, mosquitoes and flies sang in the sixth nine hundred and fifty-four, I put on clothes and sheets in the seventh nine hundred and sixty-three, I stepped barefoot in the mud in the eighth nine hundred and eighty-one, and I added green leaves in the ninth nine hundred and eighty-one." ◆ Xiangqu: "The solstice in winter is the first nine handcuffs, and it seems that the mouth is spicy in 29 18 years. Fire was like honey in 3927, the stove was turned off in 4936, the door was opened for heating in 594 15, and the willow was green in 6954; In 7963, pedestrians took off their clothes, in 8972, catkins flew all over the ground, and in 998 1 year, they put on coir and hats.
