Who is the winter solstice to commemorate?

The winter solstice is to commemorate Zhang Zhongjing's festival.

Zhang Zhongjing resigned from his post and returned to his hometown. When he returned home, it was winter. In order to help the people get rid of the cold in winter, he used mutton, some cold-dispelling herbs and dough to wrap it in the shape of ears, made a medicine called "cold-dispelling and charming ear soup" and gave it to the people to eat, which cured the people's frozen ears. Later, on the winter solstice, people imitated eating and became a custom, which has been passed down to the present.

The winter solstice, also known as Solstice, Winter Festival, Sub-Year, etc., has both natural and humanistic connotations. It is not only an important solar term among the 24 solar terms, but also a traditional folk festival of ancestor worship in China. The winter solstice is one of the four seasons and eight festivals, which is regarded as a big holiday in winter. In ancient times, there was a saying that the winter solstice was as big as a year.

customs vary in content or details due to different regions. In southern China, there is the custom of offering sacrifices to ancestors and feasting on the winter solstice. In the northern part of China, it is a custom to eat jiaozi every winter solstice.

Meteorological changes in the winter solstice

After the winter solstice, although the solar altitude angle gradually increased, it was a slow recovery process, and the heat lost every day was still greater than the heat received, showing a situation of "making ends meet". On the "March 9, April 9", the accumulated heat is the least, the temperature is the lowest, and the weather is getting colder and colder. China has a vast territory, and the climate and landscape vary greatly from place to place.

Although the days on the winter solstice are short, the temperature on the winter solstice is not the lowest. It won't be very cold before the winter solstice, because there is still "accumulated heat" on the surface, and the real cold winter is after the winter solstice. Because of the great disparity of climate in different parts of China, this astronomical climate feature is obviously late for most parts of China.

After the winter solstice, the climate in all parts of China will enter a coldest stage, which is often referred to as "entering nine days" and "counting nine cold days". The so-called "number nine" means counting from the date of the winter solstice (it is also said that it is counted from the winter solstice), counting "nine" every nine days, and so on; Count to nine until it is eighty-one days, and when the peach blossoms bloom, the cold is gone.

nine days is a unit, which is called "nine". After nine "nine", it is exactly 81 days, which is "nine out" or "nine out". From "September 19th" to "September 9th", the cold winter becomes warm spring.
