What does Lesser Heat mean?

The "shu" in "Xiaoshu" means hot. Therefore, Xiaoshu means a slight heat, which means the weather starts to get hot, but it has not yet reached its hottest point.
During the Lesser Heat period, the average temperature in southern China is around 26℃. In the low-altitude river valley areas in the southeast of South China, the daily average temperature may begin to exceed 30℃ and the daily maximum temperature may exceed 35℃; but in the northern part of the northwestern plateau, frost and snow can still be seen at this time, which is equivalent to the early spring season in South China.
However, due to the vast area and large span of our country, the climate in different places is also very different. Although it is hotter during the Greater Heat period in most areas, in some southern regions the Lesser Heat period is hotter than the Greater Heat period, or the temperatures are almost the same.

What are the phenological characteristics of the Lesser Heat solar term?

The ancient Chinese divided the Lesser Heat into three stages: " The first stage is the arrival of warm winds; the second stage is the crickets living in the house; the third stage is the beginning of eagles' prey ." During the Lesser Heat season, there is no longer a trace of cool breeze on the earth, but all winds carry heat waves; the words describing crickets in "The Book of Songs: July" include "In July, they are in the wild; in August, they are in the house; in September, they are at the door; in October, the crickets come under my bed." The August mentioned in the text is the sixth month of the lunar calendar, which is the time of the Lesser Heat solar term. Due to the heat, crickets leave the fields and go to the corners of the courtyard walls to avoid the heat; during this solar term, eagles move around in the cool high sky because the ground temperature is too high.
