When did the "99-99 Cold Protection Plan" begin?

The so-called "number nine" starts from the winter solstice, and every nine days is a "nine" until the "nine nine" is the eighty-first day. In the traditional culture of China, nine is the highest number of yang, which is also the largest number. The accumulation of nine nines is a "maximum" number, and "nine nines" means that the yang has reached the maximum.

Count from "19" to "99", and "99 is tired and the peach blossoms are in bloom" is called "99 is cool and cool". There are various customs circulating among the people to record 8 1 day of "99" and express people's good wishes that the long winter will pass as soon as possible and spring will come early.

The origin of custom:

"Jiujiu", also known as "Winter Jiujiu", is a folk solar term in winter in China. The "number nine" began the day after the "winter solstice" in late February and early February of 65438.

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 "1999 thundered for a long time."
