Do you know why it is called Count Nine Songs?

Because the number nine runs through the whole text.

The count of nine is 19 every nine days from the date of winter solstice to the 998th1day. There is a saying in China that "nine winters count". From the solstice of winter, "Nine" is to count the seasons. The specific calculation method is that every nine days from winter to Sunday is a "nine", the first nine days are called "one nine", the last nine days are called "two nine", and so on until "nine nine nine", and when the number reaches 998 1 day, it is called "nine out".

However, there is not only one version of Jiujiu Song. Different from the popular "seeing willows along the river in May, 1969", the short version of "Jiujiu Song" popular in Beijing in the Ming Dynasty says that "seeing willows along the river in July, 1989" obviously takes much longer for willows to germinate at night; Because our country spans the north temperate zone and subtropical zone, the climate change varies significantly from place to place. According to historical records and local folk records, although there are nine kinds of sayings from the north and south of the Yangtze River to the upper and lower reaches of the Yellow River, there are similarities and differences and different versions, and this difference continues to this day.

China folk widely circulated the winter solstice "99 Cold Interpretation Song": 19, 29 do not shoot; Walking on the ice on March 9 and April 9; 59 and 69, watching willows along the river; 79 River freezes, Swallow for 89 years; 99 plus 19, plowing cattle everywhere.

1929, I can't open my hand; In 3949, the ice slipped; 5969, looking up at the willows; 79 River freezes, Swallow for 89 years; Poplar landed in 1999, and apricot blossom in 19; Nine flowers can't bloom, and fruits crowd the street.
