today is December 22, 2017. The annual winter solstice solar term is coming. People think that the arrival of the winter solstice represents the coming of cold winter, while meteorological experts point out that people will enter the coldest period of the year after the winter solstice. Let the old yellow calendar introduce it to you.


"the time of day and the personnel day urge each other, and the winter solstice is sunny and spring comes again." according to the Chinese astronomical calendar, at 0:28 on December 22, Beijing time, people entered the "winter solstice" solar term in 2017, which also means that after today, people will officially usher in "several nine cold days".

as the saying goes, "the winter solstice enters nine". The winter solstice is the beginning of "counting nine cold days". Counting nine is a kind of miscellaneous solar terms among Chinese people. In Jingchu Suishi Ji, it is written: "the number of winter solstice days and ninety-one days are commonly used as the cold end." in Chinese traditional culture, nine is the extreme number, and the nine nines, that is, eighty-one, is the "largest" number. The ancient Chinese people believed that spring must have come after the winter solstice.


meteorological science experts further explained that although "several nine cold days" is the coldest period of the year, the "coldest" is from the multi-year average data, and the "coldest" also has a process of "deepening layer by layer" and "step by step".


generally speaking, the weather will go full steam into the middle of winter from "19" and "29" on the winter solstice; "March 9th" and "April 9th" are the "coldest" in the coldest period, which is often referred to as "cold in March 9th"; From May 9th, the weather gradually warmed up.


nutrition experts suggest that people might as well take appropriate supplements after entering the winter solstice, and eat more cold resistant foods, such as animal liver, carrots, sea fish, bean products and other foods rich in vitamins; Protein rich foods such as poultry and lean meat; Kelp, laver, jellyfish, shellfish and other iodine rich foods; Potato, lotus root, potato and other mineral rich foods.
