Xiaohan is the 23rd solar term among the twenty-four solar terms, the fifth solar term in winter, the end of the Zi month and the beginning of the Chou month.
During the Lesser Cold season, the sun’s direct point is still in the southern hemisphere, and the heat in the northern hemisphere is still being lost. The heat absorbed during the day is still less than the heat released at night, so the temperature in the northern hemisphere continues to decrease.
The Minor Cold in northern China is colder than the Major Cold because there is relatively less “residual heat” on the surface, which has been released by the Minor Cold, causing the temperature to drop to the lowest level. In the south, the surface is relatively hot, and its “residual heat” has not been released until the Xiaohan solar term. By the time of the Great Cold, the “residual heat” on the surface of the earth is dissipated and the temperature drops to the lowest.
