December is called "twelfth lunar month" because "Liye" is the name of "offering sacrifices to ancestors and gods" in ancient times, and there is also a saying that "there are three sacrifices to the gods after the winter solstice", that is, whenever the branches and branches of the third calendar day after the winter solstice contain earthly branches, the Northern and Southern Dynasties are fixed on the eighth day of December, which is a traditional folk custom. This memorial ceremony is called "hunting sacrifice".

Because "La" and "Hunting" are both on holiday, and "Hunting Festival" is written as "La Worship", so the year-end December is called the twelfth lunar month. This custom originated in Qin and Han Dynasties. By 22 1 year BC, Qin Shihuang unified China and ordered the establishment of a calendar, calling December, when the old and the new alternate in late winter and early spring, "the twelfth month".

After the twelfth lunar month, all parts of China entered the coldest season. This coincides with the slight cold and severe cold solar terms in China. As the saying goes, "La Qi, Bala, your chin is frozen off", and there is another saying called "slight cold, severe cold, cold turns into ice hockey". Slight cold refers to the degree of cold. Literally, great cold is more than slight cold, but in meteorological records, slight cold is often colder than great cold, which can be said to be the coldest solar term among the 24 solar terms all year round.

As the saying goes, "Cold is in Sanjiu", and "Sanjiu" happens to be in the slight cold solar terms. Because of this, in the cold winter, we should pay more attention to cold protection and health care in food, clothing, housing and transportation, spend the coldest season of the year safely and welcome the arrival of the New Year happily.
