When the sun reaches 285° of ecliptic longitude (Xiao Han), it marks the arrival of the coldest day of the year for China.
Introduction to the Great Cold Solar Term : The Great Cold is the last solar term among the 24 solar terms in the year. Around January 20th of the Gregorian calendar every year, when the sun reaches 300° of the ecliptic longitude, it is the Great Cold.

When this circulation adjusts, large-scale rain, snow, strong winds and cooling temperatures often occur.
