What is the Millennium?

Lead: "Twenty-four solar terms" says: "August Festival ... Yin Qi is getting heavier and heavier, white and revealing." As the weather gets colder and colder, you will find many dewdrops on the ground and leaves in the morning, which is named after the water vapor condenses on them at night. The ancients used four seasons with five elements, and autumn was golden and golden white, so white was used to describe autumn dew. Entering the "Millennium", I will feel a little cold at night. This is the so-called "white dew". Let's take a look at the origin of the Millennium, I hope you like it!

The origin of the Millennium:

Millennium is one of the 24 solar terms of the lunar calendar. When the sun reaches 165 degrees, it is called the Millennium solar term. Millennium is the third solar term in autumn, marking the end of Qiu Meng and the beginning of Mid-Autumn Festival. Dew is water droplets formed by condensation of water vapor on the ground or near-earth objects due to temperature drop. So the Millennium actually indicates that the weather is getting cold. At this time, people will obviously feel that the hot summer has passed and the cool autumn has arrived. The temperature difference between day and night can reach more than ten degrees. Yang Qi reached its peak in the summer solstice, and these two extremes must be reversed, and Yin Qi also rose at this time. When it comes to the White Dew, the yin gradually increases, and the morning dew gradually thickens and condenses into a layer of white water drops, so it is called the White Dew. As the saying goes, "eighteen pots of summer heat, not exposed to the Millennium." These two sentences mean that it is still hot in summer, so you must take a bath with a basin of water every day. After eighteen days, in the new millennium, don't be shirtless and naked, lest you catch cold. There is also a saying: "White dew and white fans, the autumn equinox is beautiful." This means that if there is dew before and after the white dew, the late rice will have a good harvest.

"White Dew" is a festival that reflects the temperature changes in nature. Dew is a unique natural phenomenon after the solar term of "White Dew". The weather at this time, as the Book of Rites said: "The cool wind comes, the dew falls, and cicadas sing." According to the explanation of "white dew" in the twenty-four solar terms-"water and soil condense dew, autumn belongs to gold, golden white and white dew, and qi begins to be cold". The ancients also said in Xiao Weijing: "The fifteenth day after the summer heat is white dew", and the yin is getting heavier and heavier, and the dew condenses into white. In fact, meteorology shows that at this time of the solar term, the weather becomes cool and the sun is still very hot during the day. But as soon as the sun returns to the mountains, the temperature will drop rapidly. At night, the water vapor in the air will condense and form tiny water droplets, which are very densely attached to the green stems, leaves or petals of flowers and trees and are white. Especially after the morning sun exposure, it looks more crystal-clear and attractive, thus obtaining the beauty of "White Dew".

Climatic characteristics of the Millennium;

Hongyan lai: Hongyan is small, from north to south, not a southern township, nor its home. See the rain section for details.

The mysterious bird returns: the mysterious bird sees the vernal equinox, which is also from south to north. Yan is a bird in the north, so it is said to return.

A flock of birds breeds shame: more than three animals are a group, and there are many people who live in groups. "Book of Rites" notes: "Shame, food is also." Those who mention shame hide it and wait for the winter moon.

The poem "The White Dew" says: "Declining lotus rolls a jade photo, and the west wind cools all night. The sound of mosquitoes is very quiet, and Bordeaux red wine is a bit fragrant. " (Heshui Zuo)

weather

After plants began to have dew entering the Bailu solar term, summer monsoon was gradually replaced by winter wind, cold air turned to attack, and warm air gradually retreated. Cold air going south in batches will often bring a certain range of cooling. People like to use the proverb "it's cold in the autumn night in the white dew" to describe the situation that the temperature drops rapidly.

At this time, the precipitation in northern China is obviously reduced, and the autumn is crisp and dry. During this period, the first autumn rain in the middle and lower reaches of the Yangtze River can often alleviate the previous water shortage. However, if the cold air meets a typhoon, or the cold and warm air are evenly matched, the two sides are in a dilemma, and heavy rain or low temperature and continuous rain are not good for the growth of autumn crops. Continuous rainy weather often occurs in the eastern part of Southwest China, South China and West China. There may be heavy rain caused by tropical weather system (typhoon) in the southeast coast, especially in the south China coast. In addition, autumn drought, forest fire and first frost may also occur in some areas at this time. If the summer droughts in the middle and lower reaches of the Yangtze River, West China and South China are not nourished by autumn rain, summer and autumn droughts may all form. There is a proverb that says, "There is no drought in spring, and the drought in autumn is halved. Building houses in spring drought and breaking grain in autumn drought. " In some northern areas, such as Shaanxi, Shanxi, Gansu, North China and other places in the northwest, autumn precipitation is inherently less. If severe autumn drought occurs, it will not only affect the harvest of autumn crops, but also delay the sowing and emergence growth of autumn sowing crops and affect the harvest of the following year. In addition, with the autumn drought, especially the dry air and the increasing wind in mountainous forest areas, the forest fire risk in autumn began to enter a period of high incidence.

On August 15th, the wild goose gate opened, and the geese came, with frost on their heads. Frost is caused by the invasion of cold air. The daily average temperature is above 0℃, and the surface temperature drops below 0℃. The water between crop cells freezes, constantly absorbing the water in the cells, leading to cell dehydration and crop withering or death. Sometimes, although there is no frost on the surface of plants, crops will still be frozen because the surface temperature is below 0℃. This phenomenon is called black frost and it is also a kind of frost.

Millennium folklore:

Tips for life in solar terms in the Millennium

As the saying goes, "eighteen pots of summer heat, not exposed to the Millennium." It will still be hot in summer, so you need to take a bath with a basin of water every day. 18 days later, in the Millennium solar term, if you don't go shirtless, you will catch cold.

Millennium is a typical autumn climate, which is prone to dry mouth, dry lips, dry nose, dry throat, dry stool and chapped skin. There are many ways to prevent autumn dryness. You can eat more foods rich in vitamins, and you can also choose some traditional Chinese medicines that can disperse the lung and eliminate phlegm, nourish yin and replenish qi, such as ginseng, radix adenophorae, American ginseng, lily, almond and Fritillaria cirrhosa, which have many good effects on relieving autumn dryness. For the general public, simple and practical medicated diet and dietotherapy seem to be more acceptable.

Covering spring and freezing autumn is a classic key to health preservation. Of course, autumn freezing is not suitable for everyone. For example, diabetic patients have poor local blood supply. If blood vessels are stimulated by cold air at once, vasospasm will easily occur, which will further reduce blood flow and easily lead to tissue necrosis and diabetic foot. In addition, it is often accompanied by diabetes and cardiovascular and cerebrovascular diseases, and cold air stimulation is more likely to induce cardiovascular and cerebrovascular diseases and even lead to myocardial infarction. Therefore, it is best for diabetics not to get cold in autumn. In addition, the elderly and children with weak constitution, patients with cardiovascular and cerebrovascular diseases, patients with chronic bronchitis, asthma and arthritis are not suitable for "autumn freezing".

If the temperature difference between morning and evening is large, clothes and quilts should be added in time, otherwise it is very easy to catch a cold, and patients with chronic diseases such as bronchitis, asthma and peptic ulcer are also easy to induce or aggravate the condition. The epidermis at the navel is the thinnest, and there is no adipose tissue under the skin, but it is rich in nerve endings and nerve plexus, which is sensitive to external stimuli. If you don't protect yourself properly, sleep at night and expose your abdomen or love to wear navel clothes, the cold can easily invade your body through your navel. If the cold goes straight to the stomach, there will be acute abdominal pain, diarrhea and vomiting; Over time, cold gradually accumulates in the lower abdomen, which will also lead to diseases of the urogenital system. The six important meridians of the human body are distributed in the foot, and the blood circulation is the most unobstructed when the foot is far from the heart. Therefore, there is a saying that "cold starts from the feet and heat dissipates from the head". Studies have confirmed that cold feet are the chief culprit of colds, bronchitis, indigestion, insomnia and other diseases. Therefore, in the Millennium, we should pay attention to keeping feet warm, and shoes and socks should be loose and comfortable to absorb sweat.

green tea

Speaking of the Millennium solar terms, autumn is getting stronger. In the old days, Nanjing people attached great importance to the "coming" and "going" of solar terms, and gradually formed solar terms customs with local characteristics in Nanjing.

Speaking of Bailuyuan, the old Nanjing who loves tea has a special liking for "Bailuyuan Tea". At this time, the tea tree is in the excellent growth period after the summer heat. Bailu tea is neither as fresh and tender as spring tea, nor as dry and bitter as summer tea, but it has a unique sweet and mellow taste, which is especially loved by old tea customers. Moreover, the spring tea stored at home has basically been "consumed", and at this time, Bailu tea is being picked up, so before and after Bailu, a tea customer asked someone to buy some Bailu tea.

rice wine

Zixing Xingning, Sandu and Liaojiang have always had wine-making customs. Every year on the Millennium Festival, every family will make wine and drink "local wine" when receiving guests. Its wine temperature is spicy and slightly sweet, so it is called "Bailu rice wine". The best of Bailu rice wine is "Chengjiu", which is named after being brewed with Chengjiang water. Cheng wine, an ancient tribute wine, enjoys a high reputation. "Notes on Water Classics" records: "There is a backwater in Chen County, which flows to the northwest of Dongshan in the county, flows to Lei, and turns south. There is a pub in the county brewing at the foot of the mountain, which is called' Chengjiu' and Fengtong." Lu wine is passed down from generation to generation. Jin Shu's Wudi Collection: "Commend and praise in the ancestral temple", which shows that it has been as long as Lu. "Nine Domains" also said: "Chengshui is in Xingning County, Chenzhou today, which originated from Cheng Xianglai. This water is used to make wine, hence the name' into wine', which is different from wine. " Cheng Xiang is the area around Sandu and Liaohe today. From the Southern Song Dynasty to the early Republic of China, Zixing was called Xingning, so it was called Xingning County in Chenzhou. Besides taking water and choosing solar terms, the brewing method of Bailu rice wine is quite unique. First, white wine (commonly known as "earth-burned") and glutinous rice distiller's grains are brewed, and then the white wine is poured into the distiller's grains according to the ratio of 1:3, and it is put in jars for drinking. For example, craft wine must be mixed with a proper amount of water (boiled), then sealed in a jar, buried underground or in a cellar, or buried in fresh cowshed sludge, and it will take years or even decades to take it out. The wine, which has been buried for decades, is brownish red in color, silky smooth when poured out, instant in the mouth, fragrant and full of stamina. In the Annals of Xingning County compiled in the first year of Guangxu reign (1875), it is said that "the color is green and mellow, and the longer it lasts, the better it will be", and "it can be brewed for a thousand days, and you will be drunk when you go home". The Notes on Water Classics also records that a writer of the Southern Liang Dynasty chatted with his friend and said, "Let's say,' Wine travels a thousand miles, what is empty talk?' He said,' Cheng Xiang in Guiyang has a thousand miles of wine, and waking up at home is also an example.' In Nanliang, Xingning belonged to Guiyang County. There is also the custom of brewing Bailu rice wine in old Nanjing, which comes from southern Jiangsu and Zhejiang. In the old society, Bailu went to Jiangsu and Zhejiang rural areas every year, and every family made wine to entertain guests. People often brought Bailu rice wine into the city. Bailu wine is made from glutinous rice, sorghum and other grains, which is slightly sweet, so it is called "Bailu rice wine". Until the 1930s and 1940s, there were still zero copies of Bailu rice wine in hotels in Nanjing, and then it gradually disappeared.
