Proverbs of solstice winter

As the saying goes, "winter solstice, 192.5 miles, 295 miles."

It is necessary to start "counting nine" during the winter solstice solar term. The so-called "counting nine" means that the winter solstice solar term is regarded as the first day of counting nine, and then it is called "nine" every nine days. After 99 days, the cold winter passed. Now many children can sing a nursery rhyme: 1929, don't shoot, walk on the ice in 1949, watch the willows along the river in 59 and 69, open the river in 79, swallow it in 89, and plow cattle everywhere in 99 and 19. This reflects the cold weather in the process of climate change, which also means "winter solstice meets nine"

On the day of the winter solstice solar term, the sun will run to 270 degrees of the yellow meridian, and at this time, the sun will almost directly hit the tropic of Capricorn. Therefore, on the day of winter solstice, the day is the shortest and the night is the longest in a year in all parts of the northern hemisphere. After the solar term of the winter solstice, we begin to walk back, and the direct sunlight point moves northward from the tropic of Capricorn, so the days in the northern hemisphere will become longer and shorter day by day. This is the truth of the agricultural proverb "Eating noodles on the solstice in winter can grow a line in a day".

The winter solstice is the first day of counting nine, and September 19 is the ninth day from the winter solstice to the winter solstice. Therefore, 192 mile and a half means that after 1999, the daytime is about 18 minutes long. At this time, people can walk two and a half miles normally. By the end of February 9, the day will last about 36 minutes and people will be able to walk more than 5 miles. The ancients couldn't tell exactly how long winter would last until the next day, but they found subtle changes. They can walk two and a half miles more at the end of September and five miles more at the end of February, which shows the great wisdom of the ancients.
