What does summer heat mean? What's the point of being hot in summer?

The great summer heat is one of the 24 solar terms in the lunar calendar, which means that there is the most sunshine and the highest temperature. 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 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.

On the Great Summer Festival, Putian people have the custom of eating litchi, mutton and rice grains, which is called "over the Great Summer". In summer, relatives and friends often give litchi and mutton as gifts.
