What is the solar term of 1999?

Jiujiu is a general term used by ancient people in China to indicate the date from winter to the future or 8 1 day from summer to the future.

The solstice after 8 1 day in winter is called "Winter 99", and the solstice after 8 1 day in summer is called "Summer 99". This term is still very popular today, and people generally call it "Winter 99". Every nine days is a nine, which is called the ninth day, the second day, the third day, until the ninth day, which is called "counting nine cold days". This is for the winter in climate.

Usually winter 99 is an agricultural proverb compiled according to climate change: for example, "1999, if you don't make a move in 1999, 1999, if you walk on the ice in 499;" If 1999 and/699 look at green willows along the river, 1999 opens the river, 1999 brings geese, 1999 brings catkins to the ground, 1999 brings cattle everywhere, "or"1999 " Count to five or nine and cut the wellhead; Play six or nine heads in spring and watch weeping willows along the river; Seven or nine frozen rivers open, and eight or nine geese come; 1999 and 1999, cattle are everywhere.

Seasonal alternation of 24 solar terms

The twenty-four solar terms basically summarize the exact time of the alternation of four seasons in a year and the laws of some natural phenomena such as phenology in nature. Throughout the year, beginning of spring, Changxia, beginning of autumn and beginning of winter started from "Sili". Four seasons alternate throughout the year, and "four stands" means the rotation of four seasons, reflecting the changes in phenology and climate, such as spring, summer, autumn harvest and winter storage, as well as the changing laws of sunshine, rainfall and temperature.

China's low latitudes (southern regions) are characterized by abundant precipitation, abundant sunshine, small temperature difference between winter and summer, and obvious seasonal changes in sunshine, precipitation and other climatic factors. Mid-latitude areas (northern areas) have less precipitation, dryness and large temperature difference between winter and summer. When the season changes, the temperature of climate elements changes obviously, while the temperature difference between the four seasons in the mid-latitude area is large and the temperature changes obviously.
