What does 192939 mean?

There is a saying in the China lunar calendar called "Jiujiu", which is used to calculate the seasons. The calculation method starts from the date of winter solstice, and every 9 days, it is counted as "September 19", and it is extrapolated from time to time. The first nine days are called 19, the last nine days are called 29, and the last nine days are called 39 until 99,19,90 days.

There are nine songs in the countryside: "1929 don't shoot, walk on the ice in 3949, watch the willows by the river in 5969, open the river in 79, add 19 in 89 years, and plow cattle everywhere."

That is to say, with the continuous increase of nine days, the cold weather will continue to pass and usher in spring. However, from the number nine song, everyone knows that 3949 is the coldest weather, and rivers, lakes and seas are frozen away.

Extended data

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 largest number. People in ancient China believed that after the solstice of the 998th1winter, spring would definitely come.

The winter solstice is the first day of September 19. We have a saying here that "winter counting nine" means counting nine from the day of winter solstice, so the winter solstice is the first day of September 19.

Starting from the solstice of winter, counting backwards for nine days, the weather will change from the cold of winter solstice to the "warm day of late spring". Because the process of "counting nine" is the process that the cold pole turns warm and the cold air turns warm, people often call this 998 1 day "nine days" and "counting nine cold days"
