Is Xiaohan a good day?

Minor Cold is the coldest time of the year, and it is during this period that people can fully welcome the arrival of the new year. However, it is also the coldest time of the year in terms of climate, and the temperature begins to reach freezing levels. Minor Cold marks the beginning of the coldest days of the year. As the saying goes, "The coldest days are in the 39th day of winter". The "39th day of winter" is mostly from January 9th to 17th, which is also within the Minor Cold solar term. In most parts of China, the coldest time is often during the Minor Cold. Weather proverbs popular in various places can serve as evidence. For example, in North China, there is a saying that "During the Lesser Cold and Greater Cold, water turns into ice", while in the Jiangnan area, there is a saying that "During the Lesser Cold and Greater Cold, it is so cold that ice balls are formed".
In ancient times, it was called the time when wild geese fly south. The Lesser Cold, which is when the wild geese fly south, is considered the coldest time of the year and people begin to enjoy the joy at the end of the year. On the day of Lesser Cold, "the geese fly north". The ancients believed that among migratory birds, wild geese migrate according to the yin and yang. At this time, the yang energy has moved, and the geese flying north have already sensed the yang energy. The beginning of Minor Cold usually marks the beginning of the twelfth lunar month, which is less than a month away from the New Year, so the festive atmosphere becomes stronger and people begin to get busy writing Spring Festival couplets, cutting window flowers, going to the market to buy New Year pictures, lanterns, firecrackers, incense, etc., in preparation for the Spring Festival.

What is the origin of the Minor Cold solar term?

Lesser Cold, like Greater Cold, Lesser Heat, Greater Heat and End of Heat, is a solar term that indicates changes in temperature. It is said in the Collection of Explanations of the 72 Seasonal Changes in the Lunar Calendar that "the cold is still mild at the beginning of the month...and severe in the middle of the month." This means that in the Yellow River Basin, the severe cold was colder than the minor cold at that time. And because Minor Cold is in the last few days of "Erjiu", it enters "Sanjiu" a few days after Minor Cold, and the Minor Cold in winter corresponds to the Minor Heat in summer, so it is called Minor Cold. The Great Cold, which comes after the Lesser Cold, is also very cold during the "four nine days of cold" when "sleeping is like sleeping outside", and the Great Cold in winter corresponds to the Great Heat in summer, so it is called the Great Cold.
The characteristic of Minor Cold is that the weather is gradually getting colder, but it is not yet extremely cold. The "Three Nines" of midwinter are basically within this solar term, so there is a saying that "Minor Cold is better than Major Cold". This is because during the previous winter solstice, the ground surface receives the least sunlight and heat, but there is still heat supplement from deep in the soil, so it is not the coldest time of the year. After the winter solstice, which is around the "Three Nines", the heat deep in the soil is also consumed. Although the amount of sunlight and heat increases slightly, it is still not enough, so the lowest temperature of the year appears.
"Minor Cold and Greater Cold are so cold that ice forms." Minor Cold indicates the degree of coldness. Literally, Greater Cold is colder than Minor Cold; but in meteorological records, Minor Cold is colder than Greater Cold. It can be said to be the coldest solar term among the 24 solar terms in the year. It is often said that "the coldest days are in the 39th day of winter", and these "39th day of winter" happen to be within the Minor Cold solar term.
