It will not be cold in a few years.

As the saying goes, "it's hot in three days, cold in four or nine days", and the coldest period in a year is "three or nine days". Count to nine until the eighty-first day, when the peach blossoms open at nine o'clock. At this point, the cold has gone and the weather is getting warmer.

Counting to nine is one of the popular customs in China. Counting nine means counting from the date of winter to Sunday (also called counting from winter to Sunday), counting nine every nine days, and so on. As the saying goes, "it's hot in dog days, but cold in dog days", and the coldest period of the year is "March 9, April 9". Count to nine until the eighty-first day, when the peach blossoms open at nine o'clock. At this point, the cold has gone and the weather is getting warmer. Due to the vast territory of China, the climate varies greatly from place to place. Only parts of China, not all parts of the country, correspond to the winter solstice "9981, nine peach blossoms, deep spring and warm days", and some cold areas have no breath of spring.
