What is the information about high temperature in summer?

Summer is one of the twenty-four solar terms of the lunar calendar, and the sun is located in the yellow meridian 120. In the hot summer, China people have the custom of drinking tea, drying ginger, burning incense and drinking mutton soup.

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 kinds of fireflies in the world, which are divided into aquatic and terrestrial. 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.

"Rice is laughing in the field and people are jumping in the house." High temperature in midsummer is very beneficial to crop growth, but it has obvious adverse effects on people's work, production, study and life.

Generally speaking, there are obviously more people suffering from heatstroke in hot days when the maximum temperature is higher than 35℃. In hot days with the highest temperature above 37℃, the number of people suffering from heatstroke will increase sharply.
