There is a saying "1929 don't shoot, walk on the ice in 1939, and watch the willows along the river in 4959". Does anyone know?

Followed by: 79 rivers open and 89 geese come. 99 plus 19, plowing cattle everywhere.

From "Song No.9" Beijing Edition: 1929 No shot. Three, nine, four, nine, walking on the ice. Look at the willows by the river. Seven or nine rivers open and eight or nine geese come. 99 plus 19, plowing cattle everywhere.

Explanation:

There is a folk proverb in China that "the first nine days are warm, and the last nine days are cold". It turns out that if the first nine days are warm, the next winter will be particularly cold. Therefore, it is said that "the first day is not greedy, and the rain and snow continue to winter." "Yanjing Age" said: "The winter solstice on March 9 is difficult." It means that it has entered the coldest stage in cold weather since March 9.

Later, people generally thought that March 9 was the coldest day, but in fact, April 9 was the coldest time in winter. It was only a few days before March 9 that the temperature changed greatly, and suddenly it became cold, so the body did not adapt, so it was particularly cold. On April 9, although the temperature was lower than that on March 9, the temperature difference changed little, and it didn't feel as cold as when it entered March 9 from February 9.

Since the winter solstice, 349 is just near the great cold in the twenty-four solar terms.

The custom of counting to nine:

The custom of "painting nine" appeared in the Ming Dynasty. The so-called painting is actually a picture that calculates the warm date of spring after the winter solstice. In the Qing Dynasty, there was "1999 Poems for Eliminating Cold", in which there were four and thirty-six sentences every nine days, ranging from "Huang San ruled the world" in ancient times to "the golden years of Qing Dynasty" in this dynasty. It can be called an elegant historical "memorabilia".

After "painting nine", the custom of "writing nine" appeared in Qing Dynasty. "Writing Nine" has a strong cultural flavor, and often uses words such as "weeping willows in front of the pavilion and cherishing the spring breeze" or "sending fragrant flowers into the house in the spring vestibule" (traditional). Tick them into a picture first and fill them in from the ninth day (similar to "painting red" in calligraphy practice).

Black with a thick brush, nine strokes per word, one stroke per day, and it takes just 8 1 day to fill in these nine words. Interestingly, after filling in a stroke every day, you have to use a fine brush to record the weather of that day on the strokes. Therefore, a line of "writing nine" is also more detailed meteorological data in the past nine days.
