What are the solar terms behind the summer solstice?

The summer solstice is followed by a small summer solar term. Summer is 1 1 of the 24 solar terms. On July 7th or 8th every year, when the sun reaches 105, it is a slight summer heat. Summer heat, which means hot, is a little hot, not very hot. It's getting hotter, but it's not the hottest. In ancient China, the summer heat was divided into three periods: "First, it was warm and windy; Second, wait for crickets to live in space; The third waiting eagle began to crow. "

Extended data:

When the warm wind arrives, it means that after the light summer, there is no cool wind on the earth, and all the winds are carrying heat waves.

Second, waiting for crickets to live in space, which is called "cricket" by northern customs. A class of harmful insects with dark brown body and aggressive males, whose wings can make sounds when rubbed. The frequency of crickets' sounds depends on the number of times they hit their teeth per second, ranging from 65,438+0,500 cycles per second for the largest cricket species to nearly 65,438+00,000 cycles per second for the smallest cricket species. The rate of singing is directly related to the temperature, and increases with the increase of temperature. The most common song is the courtship that attracts females; There are courtship sounds that induce females to mate, and there are also fighting sounds that drive away other males.

Ju Yu, the second waiting cricket, pointed out that five days later, due to the heat, the cricket left the field and went to the corner of the yard for the summer.

The three-waiting eagle is a kind of raptor. Eagle is a typical representative of eagle-shaped birds of prey. There are three most common species in China: goshawk, sparrow hawk and sparrow hawk. The word eagle in a broad sense is also often used to refer to other birds of the family Falconidae (such as kites, _ and harriers), and even to some birds of the family Falconidae (such as falcons and caracaracara eagles). It is also the suffix of some non-eagle birds' names (because there are many analogies in Chinese names).

Three waiting eagles begin to gather, which means that in five days, eagles will move in the cool high air because the ground temperature is too high.
