What does it mean to give Han Mei nine days today?

Nine days is the coldest time in winter.

"Jiujiu", also known as "Winter Jiujiu", is a folk solar term in winter in China. The "number nine" is counted from the date of the "winter solstice" (February 2 1 or 22, Gregorian calendar 65438) every nine days. 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 is not the coldest from 1929 to 29, but "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.
