How to recite nine songs?

If you don't do this in 1929,

Walking on the ice in 3949,

Look at the willows in 5969,

Seven or nine rivers opened, and eight or nine swallows came.

99 plus 19, plowing cattle everywhere.

Jiujiu Song is a folk song circulating in northern China, which reflects the change of solar terms.

From the winter solstice in late June, 65438 to February every year, a "nine" is counted every nine days, all the way to the eighth1day of the "nine-nine plus one-nine"-90 days, counting nine days.

The number nine songs is catchy, apt and true, and vividly shows the changes of natural scenery from severe winter to early spring.

When the custom of counting nine originated, there is no exact record yet, at least it was popular in the Southern and Northern Dynasties. The Chronicle of Jingchu written by Zong Yi of Liang Dynasty: "The number of days in the winter solstice is 9981, which is the end of cold."
