This time of year belongs to the summer solar term.

There is only one solar term, which is 1 1 solar term among the 24 solar terms. The time point is between July 6th and 8th in Gregorian calendar every year, which is the end of noon month and the beginning of non-month, when the sun reaches 105.

July 7th is the Summer Day every year. "Dou Zhixin is a mild summer heat, and the weather is already hot, so it has not yet reached the silt pole, hence the name". The longitude of the sun is 105 degrees. It's already very hot, but it's not the hottest time yet, so it's called Xiaoshu.

On July 7th or 8th every year, when the sun reaches longitude 105, it is considered as a slight summer heat. "Twenty-four solar terms": "June Festival" ... It is also hot in summer, and it is small at the beginning of the month, big in the month, and still small today. "

Summer is hot. The ancients thought that the summer heat period was not the hottest time of the year, so it was called summer heat. There is also a solar term ballad: "Little summer is not hot, big summer is three days." It is pointed out that the hottest period of the year has arrived, but it has not reached the extreme hot level.

As the saying goes, "the heat is at three volts." The dog days in China generally appear in the summer to the next 28 days, which is the so-called "summer solstice is the first of the night"

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. " In summer, there is no cool wind on the earth, and all the winds carry heat waves.

The Book of Songs? In July, the words to describe crickets are "July is in the wild, August is in the house, September is in the house, and October crickets enter my bed."

August mentioned in this paper is June in the summer calendar, which is a short time in summer. Because of the heat, crickets leave the field and go to the corner of the yard to escape the heat. In this solar term, the eagle is in the cool high air movement, because the ground temperature is too high.
