What is the origin of the great summer heat?

The ancient summer heat in China is divided into three periods: "Rotten grass is firefly; Second, wait for the soil to moisten and cool off the heat; It will be fine when it rains. " There are more than 2000 species of fireflies in the world, which are divided into aquatic and terrestrial species. Terrestrial fireflies lay eggs on hay, and when it is hot, fireflies ovulate, so the ancients thought fireflies were made of rotten grass.

The second weather is that the weather becomes sultry and the land is wet. The third kind of weather is frequent thunderstorm, which weakens the heat and humidity, and the weather begins to transition to beginning of autumn.
