In the cold winter, the long-standing folk song 1999, like the spring breeze, blows people's hearts and brings them happiness. At the same time, 99 ballads are also a reflection of folk culture. Different regions have different 99 ballads and different cultural customs.

For example, the "Jiujiu Song" in the middle and lower reaches of the Yellow River is (like this): 1929 did not shoot; Walking on the 3949 River; 5969 see willows along the river; Seven or nine talks, eight or nine geese come; 1999 and 1999, cattle are being farmed everywhere.

In Jiangnan, the traditional "Jiujiu Song" goes like this: 1929, I met my husband; On March 27th, cymbals (an ancient musical instrument, meaning the fence crackled with cold wind) were played at the fence head. 4936, the night is like a heron (the night is cold like a crane); In 5945, the sun opened the door, and in 6954, poor children fought for spirit; In 7963, cloth sleeves were worn on the head; In 8972, the cat looked for the sun; Plow and rake go out together.

The coldest weather is usually "March 9 and April 9", so some folk proverbs just illustrate this problem. In March and April in Jilin, dogs were frozen to death, and in March and April in Jiangsu, the old man who picked up dung ran all over the street. It can be seen that the temperature difference between different places is large.
