"Sanjiu" refers to the third "nine days" from winter to the future, that is, the 19 to the 27th day from winter to the future. "The third nine days after the winter solstice" refers to "March 99", which is also the day when "March 99" and "April 99" intersect, not "March 99", that is, "March 99" is nine days instead of one day. People say, "it's cold for nine days, and it's cold on March 9." "Sanjiu" generally appears during the winter solstice to the great cold. Entering March 9, the cold reached its peak, and the biting cold wind was blowing to the earth. People need to face the cold challenge bravely.

Calculation method of nine

There is a saying in China that "count nine winters". From the solstice of winter, "Nine" is used to calculate the seasons. The specific calculation method is to start counting from the winter solstice (about February 22nd of today's Gregorian calendar) (the winter solstice is called "September 9th", which means that the cold weather starts counting for nine days), and every nine days are called "September 9th", the first nine days are called "September 19th", the second nine days are called "February 29th", and so on until the numbers are full. At this time, winter has passed and spring has arrived.

Of course, the pace of spring varies from place to place. Although it has reached the ninth year, the vast northern region has not yet entered the meteorological spring. Spring usually occurs in the first half of March in the south of the Yangtze River, from the second half of March to the first half of April in the north of China, and from April to May in the north of the Great Wall (the average daily temperature for five consecutive days is above 10℃). See "Spring".

The custom of old Beijing is to draw a "cold picture in September and September" from the solstice of winter, which has been recorded in the works of Ming people. This map is a plum blossom map, which depicts a plum blossom. It has 8 1 petal (representing 998 1 day). Dye a petal with a pen every other day. After 8 1 day, 8 1 petal has all been dyed, and spring has arrived, so it is called "99-99 cold relief map". Moreover, in Beijing in the Ming Dynasty, there was an engraved Cold Map of 1999, which was sold in the market, which was more convenient, and there was a Song of 1999 next to it.
