The last two of the 24 solar terms are Xiao Han and Da Han, first Xiao Han and then Da Han. After these two solar terms, we will usher in a new round of solar terms. The solar term of Xiaohan is coming soon. What's the difference between Xiaohan and dabhan? Which day is colder, Xiao Han or Da Han?
When the Yellow meridian of the sun reaches 285 degrees, the solar term begins. Cold means cold, and small cold means the degree of cold. At the beginning of the small cold solar term, the average temperature in Beijing is generally above - 5 ℃, and the extreme minimum temperature is below - 15 ℃; in the north of Northeast China, it's really an ice and jade world. It's all winter. Xiaohan, the 23rd solar term in the 24 solar terms of the lunar calendar, is also the fifth solar term in winter, marking the official start of the season of winter. When the sun reaches 285-deg, it marks the coldest day of the year for the land of Shenzhou.
Greater Cold
The cold is the last of the 24 solar terms of the year. Every year around January 20 of the Gregorian calendar, when the sun reaches 300 DEG; of the Yellow longitude, it is cold. During the cold solar term, the atmospheric circulation is relatively stable, and the circulation adjustment period is about 20 days. When the circulation is adjusted, large-scale rain and snow weather and strong wind often appear. When the long wave ridge is 80 degrees east longitude to the West and the coastal trough is East Asia, the sustained low temperature will appear in China under the influence of the northwest wind flow control and the continuous supplement of cold air.

Which is colder, Xiao Han or Da Han?
According to the national climate statistics, there are more years when the mild cold solar term is colder than the severe cold solar term
According to China's annual climate data statistics, the coldest time of the year in most of northern China is the middle of January (10th-20th). Every year, the minor cold solar term starts from January 5-7, one solar term lasts for 15 days, and the middle day is just within the minor cold solar term. Therefore, for most parts of the north, the cold is indeed colder than the cold.
For most of the south, it is the coldest in the cold solar term. The cold solar term generally starts from January 20, and the last ten days of January is the coldest time of the year in the south. However, there are always some areas that are 'different'. In most of the year, the coldest time is in the late December in Western Sichuan and Yunnan, probably in the winter solstice; in some areas of Tibet and Xinjiang, the coldest time is in the early January.
