Counting nine days is a nine.

The ninth floor of the sky-the highest sky

It has been a cold day in China since the winter of November. Astronomical experts say that the Ninth Five-Year Plan is a more applicable solar term in northern China, especially in the middle and lower reaches of the Yellow River.

From the date of winter solstice, you enter the number nine, commonly known as "cross nine", and then every nine days will be a unit, which will be called "nine". After nine "nines", it happens to be 8 1 day, which means "nine out".

In the traditional culture of China, nine is the extreme number, which is the largest, largest and longest concept. Nine nines is eighty-one, which is the "maximum" number. People in ancient China believed that after the solstice on September 8 1 day, spring must have arrived.

The starting time of extended data 1 and "number nine": it is calculated from the day of "winter solstice" every year (2 1 or 22 in February of Gregorian calendar 65438).

2. The custom of "counting nine":

There are many traditional customs in China, among which "Jiujiu Song" is the most extensive and long-standing. These songs skillfully use the phenological phenomena in nature and vividly reflect the laws of weather changes during the Ninth Five-Year Plan period.

19 to 29, the weather is not the coldest, just "1929, I can't reach it." Most of March 9 and April 9 belong to the slight cold solar terms, which is the coldest time of the year, so we say "March 9 and April 9, freezing women 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 "thunder" solar term, so the thunder of 1999 made a lasting noise.
