The origin of the Great Heat solar term

Every year on July 23 or 24, when the sun reaches 120° of ecliptic longitude, it is the "Great Heat" solar term. "Great Heat" and "Little Heat" are both seasons that reflect the heat of summer. "Great Heat" means extreme heat. "Collection of the Seventy-Two Hours of the Monthly Order": "In the middle of June,...heat means heat. The heat is divided into big and small. The first month is small, the middle of the month is big. Today, the heat is still strong." This is the time. Around the time of "mid-voltage", most areas across the country enter the hottest period of the year, which is also the period when temperature-loving crops grow the fastest. However, natural disasters such as droughts, floods, and typhoons occur frequently, and tasks such as drought relief, flood prevention, typhoon prevention, and field management are Very heavy.

In ancient my country, the Great Heat was divided into three periods: "The first period is when the rotten grass becomes the firefly; the second period is when the soil is moist and the heat is moist; the third period is when it rains heavily." There are about 2,000 kinds of fireflies in the world, divided into aquatic and terrestrial. There are two types of fireflies. The terrestrial fireflies lay their eggs on dead grass. During the heat, fireflies hatch out of their eggs, so the ancients believed that fireflies were transformed from rotten grass. The second period means that the weather starts to get hot and the land is very humid. The third period means that heavy thunderstorms often occur. This heavy rain weakens the summer humidity and the weather begins to transition to the beginning of autumn.

We know that under the control of a high-pressure system, high pressure produces downdrafts. The temperature increases during the sinking process, making the sky clear and less cloudy, and the solar radiation is strong. From the end of July to the beginning of August, it is the active period of the western Pacific subtropical warm high pressure. It often stays in eastern my country. When it is strong, it can move westward and control the eastern part of southwestern my country, such as eastern Sichuan, Chongqing and other places. Similarly, in summer, many areas in mainland my country are often controlled by continental high pressure, which also causes sinking and increasing temperatures. Clear skies with few clouds and hot ground bake the atmosphere, keeping temperatures high. It can be seen that the high pressure system is the basic condition for the generation of high temperature weather, and the maintenance of high pressure means the continuation of high temperature weather. Generally speaking, on hot days when the daily maximum temperature is higher than 35°C (called "hot days" in meteorology), the number of people suffering from heat stroke increases significantly. When the maximum temperature of the day reaches above 37°C (known as a "hot day" in meteorology), the number of people suffering from heat stroke will increase sharply, especially in the middle and lower reaches of the Yangtze River under the control of subtropical high pressure, where the sun is like fire, the wind is light and the humidity is high. It makes people feel even more stuffy. The "three big furnaces" along the Yangtze River - Nanjing, Wuhan and Chongqing, have an average of 17 to 34 "hot days" every year, and 3 to 14 "extremely hot days". In fact, there are many places that are hotter than the "Three Hot Stoves", such as Anqing, Jiujiang, Wanxian, etc. Among them, Guixi in Jiangxi, Hengyang in Hunan, Kaixian in Sichuan and other places, the average "hot day" throughout the year is 40 Above the sky, the entire middle and lower reaches of the Yangtze River is a big "furnace". Therefore, it is particularly important to do a good job in heatstroke prevention and cooling.

During the Great Heat, fireflies hatch out of their eggs

According to whether the Great Heat is hot or not, there are many farmer proverbs that predict the weather in the later period: For example, in the short term, "The Great Heat is hot, and the fields will be cold." The first rest; the summer is cool, and the pond is full of water." The mid-term predictions include "the summer is hot, and the autumn is cool." The long-term predictions are "the summer is very hot, and there is no frost in four months." "It is not hot in the summer, and it is not cold in the winter." , "If the summer is not hot, the winter will be rotten" etc.

In the hot and rainy season, drops of rain are like gold. There are sayings in the Jiangsu and Zhejiang areas that "the rain in the mild summer is like silver, and the rain in the severe summer is like gold", "when there is more rain in the summer, there is more rice in the store", "when the rain is abundant in the summer, there will be abundant grain and cotton" and "if there is no drought in the summer, one acre will increase by one load". If it rains before and after the Great Heat, it indicates that there will be more rain in the future. There is a farmer's proverb that goes, "If there is plenty of rain in the summer, there will be plenty of water in autumn; if there is no rain in the summer, there will be little rain, and there will be no water."

Generally speaking, the Great Summer Festival is the period of the year with the most sunshine and the highest temperature in South China. It is the period with the most abundant rainfall, the most common thunderstorms and the most concentrated days with high temperatures above 30°C in western South China. It is also the period in eastern South China. The period when high temperatures above 35°C occur most frequently. The Great Heat is also the season with the most thunderstorms. There is a proverb: "A flash in the east will not catch a drop, and a flash in the west will not be able to escape." This means that in the afternoon of summer, if lightning appears in the east, the rain will not fall here. If the lightning strikes in the west, the rain will not fall here. It will come soon and it will be too late to escape. People also often call summer afternoon thunderstorms "northwestern rain" and describe "the northwest rain falling across the road without traffic." "The summer rain is separated by the field ridge" and "the summer rain is separated by the cow's back", etc., vividly illustrate the thunderstorm , it often rains here and is sunny there, just like the poem of Liu Yuxi, a poet of the Tang Dynasty: "It is sunny in the east and rainy in the west. It means there is still sunshine even if it is not sunny."

Customs of the Great Summer Festival

The "Great Summer Boat" activity has been held along the coast of Taizhou, Zhejiang for hundreds of years. The "Great Summer Boat" was built entirely on a scaled-down version of an old three-masted sailboat, and it carried various sacrifices. After the event started, more than 50 fishermen took turns carrying the "Great Summer Boat" and marched through the streets with loud trumpets and firecrackers, and the streets were lined with crowds of people praying for blessings. The "Great Summer Boat" was finally transported to the dock for a series of blessing ceremonies. Subsequently, the "Great Summer Boat" was pulled out of the fishing port by a fishing boat, then set alight on the sea and left to float, in order to wish people a good harvest and a healthy life.

People in Jiaojiang, Taizhou also have the custom of eating ginger juice mixed with eggs during the summer season. Ginger juice can remove moisture from the body, and ginger juice mixed with eggs is "replenishing". Some elderly people also like to eat chicken porridge, which is said to be able to replenish yang.

Taiwan

During the Great Summer Festival, the waters around Taiwan are mostly full of warm-water fish. There are squid in the northeastern sea, Kojuan off Keelung, Chizong, and yellowfin seabream in the Changhua sea. wait. Taiwanese proverb: Eat pineapples during the hot summer, which means pineapples are the most delicious during this season. In addition, June 15th is the "Half Year Festival". Since June 15th in the lunar calendar is half of the whole year, after worshiping the gods on this day, the whole family will eat "half year round" together. Half year round is made from glutinous rice ground into powder. It is kneaded with red flour and is mostly cooked into sweets to taste, which symbolizes reunion and sweetness.

Drinking mutton soup

Shandong

In the southern part of Shandong, there is a custom of "drinking hot sheep" (that is, drinking mutton soup) on the day when the Great Heat comes. In Zaozhuang City, many citizens go to the local mutton soup restaurant to "drink hot mutton" on this hot day.

The habit of eating sheep in Zaozhuang is related to the local farming and climate. Zaozhuang is a famous wheat-producing area. At the time of entering the ambush, the wheat harvest is over and new noodles are on the market. It is a short agricultural slack period. The summer harvest has just passed and people are tired. It’s time to rest and enjoy themselves. What’s delicious in the countryside? That’s eating a new wheat steamed bun. He was so cruel that he killed a sheep and was unwilling to eat it himself. He took his married daughter back and took his nephew Gouzi back to his parents' home to eat new wheat steamed buns and drink mutton soup. Your daughter has been brought back, and my family can't hold you back. We also steamed buns with new noodles and killed a sheep. We also brought your daughter back and ate the sheep. So it became a folk custom.

Nutritionists have conducted in-depth research on this and believe that mutton is the most nutritious when eaten during the dog days. During the dog days of summer, heat accumulates in the human body. At this time, if you drink mutton soup, chili oil, vinegar, and garlic into your stomach at the same time, you will inevitably sweat profusely all over your body. This sweat can take away the accumulated heat in the five internal organs and expel toxins from the body, which is very beneficial to your health. .

Guangdong

Many places in Guangdong have the custom of "eating fairy grass" during the summer season. Grass jelly, also known as jelly grass and jelly grass, is a herbaceous plant belonging to the Lamiaceae family and is an important medicinal and edible plant resource.

The Great Heat is the season when there are the most crickets in rural fields. People in some areas of China have the custom of fighting crickets after dinner.
