Cultural significance of hyperthermia in summer

The significance of summer heat in daily life is to remind people that the summer heat is gradually disappearing and the weather is turning from hot to cold, so we should pay attention to preventing "autumn dryness".

Long summer is the 14th solar term among the 24 solar terms, and autumn is the second solar term. Sinus refers to the southwest of Wu; The meridian of the sun reaches 150 degrees; Celebrated every year from August 22nd to 24th in the Gregorian calendar. Summer has arrived, which is the "last summer" in the "three summers" of hot and hot weather, which means that the hot and difficult weather is coming to an end.

After the summer heat, the direct point of the sun continued to move southward, the solar radiation weakened, the subtropical high retreated southward, and the summer heat gradually disappeared. Thunderstorm activity is not as active as summer, and the general trend of rainstorm in all parts of the country is weakened. In summer, there are many folk activities, such as eating ducks, setting off river lanterns, opening fishing festivals, making herbal tea and offering sacrifices to the land.
