What does summer mean in 24 solar terms?

Summer is one of the twenty-four solar terms of the lunar calendar, and the sun is located in the yellow meridian 120. The summer solar term is the hottest period in a year, with the highest temperature and the fastest growth of crops, just before and after the Mid-Autumn Festival in the dog days. In the hot summer, China people have the custom of drinking tea, drying ginger, burning incense and drinking mutton soup.

At this time, before and after the mid-autumn period, most parts of China are the hottest period in a year, and the growth rate of heat-loving crops is also the fastest. The working people in China divide the summer heat into three periods: "rotten grass is firefly;" Second, wait for the soil to moisten and cool off the heat; It clears up 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.
