Three nine four nine coldest

As the saying goes, "Cold is on March 9th", and in some places, "On March 9th, April 9th, dogs and cats were frozen to death" exists in the "Jiujiu Song". March 9 and April 9 are often the beginning of the twelfth lunar month, so there are sayings of "freezing to death at the door of the twelfth lunar month" and "pulling Bala up and going out to freeze".

Because the earth absorbs the heat of the sun and stores it, stores it during the day and releases it at night, before the winter solstice, the heat released by the earth is less than the absorbed heat, and it accumulates slightly. Since the winter solstice, although the heat absorbed by the earth from the sun has increased due to the longer days, the heat released has been "unable to make ends meet" because the nights are still longer than the days.

On March 9 and April 9, there was a serious "heat deficit" phenomenon on the earth, so the winter solstice became colder and became the coldest time of the year.
