Why do you want to take a bath around winter?

There is no hint. The winter solstice is just an astronomical solar term, the shortest sunshine day, and the beginning of counting nine. It has nothing to do with taking a bath or not, and even the people have no words.

The winter solstice is the 22nd solar term in the "24 solar terms", and the solar calendar reaches 270 degrees. Every year, the festival is held on 65438+February 2 1-23 in the Gregorian calendar. The solstice in winter is the extreme point of direct sunlight spreading to the south. From winter to the sun, the sun shines directly on the tropic of Capricorn, and the sun is most inclined to the northern hemisphere, and the elevation angle of the sun is the smallest. In all parts of the northern hemisphere, the days are the shortest and the nights are the longest.

The solstice in winter is also the turning point of direct sunlight returning to the north. After this day, it went back, and the direct sunlight began to move northward from the Tropic of Capricorn (23 26' s), and the sunlight in the northern hemisphere (China is located in the northern hemisphere) increased day by day.

Count to nine from the winter solstice.

After the winter solstice, the climate in all parts of China will enter a coldest stage, which is often called "ninth year cold" and "ninth year cold". The so-called "number nine" refers to nine days from the date of winter solstice, which is called "nine". After nine nines, it happens to be 8 1 day, whether it is "nine out" or "nine out". From "September 19th" to "September 9th", the cold winter turned into a warm spring.

The winter solstice begins to count to nine, and the winter solstice becomes the first day to count to nine. As for "Counting Nine", there is a folk song that goes like this: "Don't do it in September, walk on the ice in March and April, watch the willows along the river in May and June, open the river in July and September, geese come in August and September, and cows go everywhere in September and September."
