What is Jiujiu Song?

1, 1929 not shooting, walking on the ice in 3949,

Five, nine, six, nine, look at the willows, seven or nine rivers are open,

Eighty-nine geese come, ninety-nine and nineteen, and cows go everywhere.

2, not 1929; 3,949 yuan to take away;

Five or nine and a half points, slag scattered; Hit six or nine heads in spring, take off your coat and change to a cow;

In 7963, pedestrians relaxed their clothes; Nine times out of ten, don't plow, just stay for three or five days;

Yang Hua blooms in September and doesn't come in September.

Song of 1999 takes advantage of people's feeling of cold and phenological phenomena (that is, changes in animals and plants caused by weather and temperature, such as willow sprouting, peach blossom blooming and geese flying). ), these are all related to the temperature at that time.

Extended data:

March 9 is the coldest time of the year. The calculation method is to count from the winter solstice of the winter non-healing day (winter to the future, the first non-healing day is called "cross nine", which means the beginning of cold), and every nine days are called "Jiujiu", the first nine days are called "Jiujiu", the last nine days are called "Erjiu", and so on until "Jiujiu", that is, the number of the ninth nine days reaches 9980. At this time, "nine peach blossoms bloom" and "spring is deep and the sun is warm".

The correct algorithm of "counting nine" begins from winter to the first nonunion day in the future. Therefore, the specific date of "September" every year is not fixed, depending on the first nonyl day after the winter solstice.

Another mistake is that the number nine is counted from the date of winter solstice, so the specific time of nine is fixed every year from the date of winter solstice, and each nine is fixed on the ninth day, 18 and the 27th day after winter solstice. The algorithm of counting nine from winter to day is wrong. As the folk proverb says, "The solstice in summer is three years old, and the solstice in winter is nine years old."
