This is the annual summer solar term.

This is the annual summer solar term: this is the annual midsummer season.

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.

"Twenty-four solar terms" said: "Summer is in the middle of June. Summer, summer, size, small at the beginning of the month, big in the month, and still hot today. " Its climatic characteristics are: "Dou refers to C as a great summer heat, and the weather in Sri Lanka is stronger than a small summer heat, so it is called a great summer heat." The summer solar term is just around the Mid-Autumn Festival in the dog days, which is the hottest period of the year, with the highest temperature and the fastest growth of crops. At the same time, various meteorological disasters such as drought, waterlogging and wind disasters are also the most frequent in many areas.

The high temperature during the hot summer is a normal climate phenomenon. At this time, if the light is insufficient, the growth of warm crops such as rice and cotton will be affected. However, the continuous high temperature weather for a long time is very unfavorable to the growth of crops such as rice. There is an agricultural proverb in the middle and lower reaches of the Yangtze River: "It is a bit dry if it doesn't rain for five days, a bit dry if it doesn't rain for ten days, and it doesn't rain in January."
