Why is summer heat called summer heat?

Summer is summer, which means to leave in the heat, representing autumn in the meteorological sense.

The word "summer" first appeared in Guoyu, and Huainanzi Astronomical Training in the Western Han Dynasty clearly listed "summer" as one of the 24 solar terms. The place in the hot summer refers to the end, and the hot summer means the official end of the hot summer. It means that it has entered the autumn in the meteorological sense. After the summer, the temperature in the area north of the Yellow River in China gradually drops. Affected by short-term reheating weather (commonly known as autumn tiger), there is still continuous high temperature after the heat, just like midsummer.

However, the summer heat gradually subsided and the temperature began to show an overall downward trend. On this day in summer, the direct point of the sun has moved from 23 26' north latitude of "summer solstice" to1128' north latitude. The sun is at longitude 150 degrees. As the height of the sun decreases, the heat it brings will also decrease.

The custom of solar terms in summer

1, eat duck

In many places in China, ducks are eaten on the day of the summer solar term, because the homonym of "duck" is "pressure", and eating ducks can suppress the anger of "summer". Ducks can be eaten in a variety of ways, including boiled duck, lemon duck, ginger duck, roast duck, lotus leaf duck and walnut duck.

2. Sheep Festival

In Wenshang County, northwest of China, the festival of sending sheep is the summer solar term. In rural areas, whenever the summer solar term comes, mothers will steam noodles for their children and then give them food. These sheep are actually noodles, indicating that the children have grown up.

3. Eat longan with porridge

Eat longan with porridge in summer, because the weather in summer is hot and the human body consumes more calories. Eating longan can supplement calories.
