When the six flying flowers enter the house, sit and watch the green bamboo turn into beautiful branches. "As the snowflakes dance and jump with light steps, the heavy snow season comes with its unique romantic atmosphere. December 6th this year is the heavy snow season. At this time, the north wind rolls over the ground, the leaves of trees fall off, the water freezes, and all things hide in winter. The world is peaceful and tranquil, and the mid winter season begins. Ice condenses and snow accumulates, and all things sleep deeply. 'When the little snow is gone, the big snow begins.'. Da Xue is the 21st solar term among the 24 solar terms, and also the third solar term of winter. Every year around December 7th in the Gregorian calendar, when the sun reaches 255 degrees yellow longitude, heavy snow arrives as scheduled. The "Explanation of the Seventy Two Seasons of the Moon" records: "Heavy snowfall occurs during the November Festival, with the most severe being the peak. At this point, the snow is abundant." This means that during this period, the weather becomes colder and the probability of snowfall is higher than during light snowfall. The size of light snow and heavy snow does not describe the amount of snowfall, but rather the presence or absence of snow. Due to the gradual decrease in surface temperature, during light snowfall, snow melts as it falls, while during heavy snowfall, snow accumulates as it falls. With snow, there can be a scenery covered in silver, and only then can there be the artistic conception of mountains accumulating jade. Of course, there may not necessarily be snow during the period of heavy snowfall, and there may also be a phenomenon of "poor snow" or even no snow during heavy snowfall. When the heavy snow season arrives, it is probably the farmers who are most looking forward to snowfall - snow has always been a symbol of harvest since ancient times. As the saying goes, "auspicious snow heralds a bountiful year", which is a summary of the agricultural production experience of our ancestors and contains profound scientific basis. "The snow covers three layers in winter and sleeps on Mantou in the coming year". The newly fallen snow is loose and porous, and can store a lot of air, which is equivalent to covering the winter crops with a quilt to protect them safely through the winter; Half melted snow with a layer of ice can reduce the occurrence of pests and diseases in the coming year. When the snow melts, it absorbs a lot of heat from the soil, which can freeze pests and insect eggs on the soil surface and in crop roots to death; According to calculations, snow contains abundant nitrogen compounds and sulfides, especially nitrogen content, which is 4 to 5 times that of ordinary water in the same volume. After the snow melts, it can not only replenish water to the soil, but also have a good fertilizing effect on the soil. Warm after the wind, cold after the snow ", accompanied by a continuous decrease in temperature. During heavy snowfall, temperatures below zero degrees Celsius become the norm in northern China. At this time, except for the non winter areas in southern China and southern Yunnan, most parts of China have entered the cold winter season. In most areas of northwest and northeast China, as well as the Yangtze River Basin, rime has gradually appeared. The mist condenses on the branches when it gets cold, forming a light and white rime. The jade trees and branches are crystal clear, as beautiful as fairy tales and dreamlike as fairyland, stunning and intoxicating. There are three periods of heavy snow: one is when the crows do not chirp; The second tiger begins to cross; San Hou Li stands out. The "wagtail" is a bird that calls at night to seek the dawn, also known as the "cold horn bird". When the sky is cold and the earth is frozen, the "cold horn bird" senses the extreme coldness and stops calling; The ancients believed that during heavy snowfall, the yin energy was extremely strong, and the so-called peak declined. The yang energy had already begun to sprout, and tigers began to engage in courtship behavior; Liting "is a type of orchid plant that can be used as a brush. At this time, everything is hidden in winter, but the tough Liting quietly takes root and sprouts, making people admire the power of life. During the heavy snowfall season, the sky and earth are closed and the water, ice, and earth are cracked. At this time, the Yin energy of nature is extremely abundant, and the Yang energy of the human body also hides inside as the Yin energy of nature becomes more abundant Cheng Niang, Deputy Chief Physician of the Oncology Department at Beijing Hospital of Traditional Chinese Medicine affiliated with Capital Medical University, introduced that at this time, health preservation is still mainly based on "nourishing and storing", with the fundamental goal of nourishing yin and protecting yang, while also paying attention to warming the kidneys and strengthening the spleen, in accordance with the natural law of closed storage. During the winter season of nourishing and warming, the weather becomes colder and colder. However, in the bustling streets, the smell of human fireworks brings a unique warmth. The steaming hot food soothes the taste buds and soothes the heart. Xiao Xue pickled vegetables, Da Xue cured meat The heavy snowfall season has arrived, which means the end of the year is approaching. In the past, many households would start marinating "salty goods" at this time. Some households in the south would hang newly made salted meat, sausages, etc. high under the eaves of their doorways to dry, and the New Year's flavor would be wafted from here. As the saying goes, 'Before the Chinese New Year, fatten up the eaves first', this unique scenery belongs to the ritual of the heavy snow season. Cheng Nian reminds that although cured meat and other foods have a strong flavor, they have a high salt content, so it is best to eat them in moderation. During heavy snowfall, the days in various parts of the Northern Hemisphere are short and the nights are long. There is a saying in agriculture, such as' heavy snow, light snow, and endless cooking ', used to describe days so short that they are almost enough to cook three meals in a row. There is a folk saying in northern Shandong that "the threshing wheel drives the door and drinks only red sticky Congee" (the threshing wheel is a cylindrical farm tool made of stone, which can be used to roll grain and level the ground), which means that when it is cold, people will stop visiting and drink warm sweet potato Congee at home to keep warm. Sweet potatoes contain a lot of dietary fiber. It is delicious and healthy to drink a bowl of hot sweet potato Congee in cold winter. Nanjing people love to eat big radishes during heavy snowfall, and the radish balls made from radishes have been popular in the southern part of the city for many years. People in the south of the old city have the habit of eating Dim sum in the afternoon. They sit around the stall. The stall owner scoops out a few balls in the boiling water, puts them in a bowl, and sprinkles some garlic flowers, which is delicious. As the saying goes, 'In winter, nourish the body; in spring, fight the tiger.' Heavy snowfall is a good season for nourishing the body. It is recommended to warm the yang and dispel the cold, nourish the kidneys and bones, and nourish the yin and essence Cheng Niang introduced that winter tonics can enhance the immune function of the human body, promote metabolism, and improve the phenomenon of coldness in the body; It can also regulate the metabolism of substances in the body, allowing the energy converted from nutrients to be stored in the body to the maximum extent, which helps to promote the rise of yang energy in the body. At this time, it is advisable to eat more foods that are rich in protein, vitamins, and easily digestible, such as lamb, beef, red dates, goji berries, hawthorn, radish, lotus root, etc. You can also eat hotpot and other foods that are a combination of meat and vegetables. At the same time, pay attention to pairing ginger and Sichuan peppercorns with foods that warm the spleen, dispel cold, and promote qi circulation. The weather is cold, so it is recommended to drink ginger jujube soup regularly to resist the cold. Avoid eating sticky, hard, raw, or cold foods; Before and after the heavy snow season, a large number of citrus fruits are on the market. It is advisable to eat some seasonal fruits such as honey oranges, pomelos, navel oranges, and snow oranges to prevent and treat rhinitis, reduce phlegm and cough. In addition, you can also eat some nuts in moderation. Nuts have a warm and warm taste, which can easily cause internal heat when eaten in other seasons. At this time, the weather is colder, and eating nuts can not only prevent internal heat, but also have a warming effect. The weather is cold and the wind is cold, warm feet and warm body. "Small snow seals the land, heavy snow seals the river." During the heavy snow season, many places in the north receive snow and rivers, and the cold wind casts the lake water into a mirror like ice surface. The vast expanse of heaven and earth is pure and one color, and people play and frolic on the glaciers, embracing the vastness and magnificence of nature. Spring is full of flowers, autumn is full of moon, summer is cool breeze, winter is snow, which has always been a joyful activity for ancient people during the four seasons. Throughout history, literati and poets have expressed their aspirations through poetry and used snow to express their emotions, leaving us with countless popular poems. Among them, there are both the solitary and exquisite "fishing alone in the cold river snow", as well as the majestic and heroic "heavy snow covering the bow and knife", as well as the free and unrestrained "Yanshan snowflakes are as big as a mat, falling piece by piece on the Xuan Yuan platform", and as passionate as "suddenly like a spring breeze overnight, thousands of trees and pear blossoms bloom"... Jingying's snowflakes become romantic and colorful because of the poet's spiritual interest. The snow scenery is beautiful, but the road surface is slippery after the snow. When traveling, it is important to pay attention to safety, especially for the elderly to prevent falls Cheng Nian reminds elderly people to avoid smooth and icy roads when traveling, and to choose sports shoes with good anti slip performance when going out. After the heavy snowfall season, the temperature further decreases, and some elderly people choose "cat winter", which means staying in a closed heated room for a long time. This can easily lead to symptoms such as dry mouth and nose, chest tightness, headache, and emotional restlessness, "said Cheng Niang. At this time, the indoor air humidity should be appropriately increased, and some water can be sprinkled on the ground or a humidifier can be used. It is also important to eat fruits and vegetables to replenish water in the body; At the same time, open windows frequently for ventilation to maintain fresh indoor air. It is best to open windows at noon or on sunny days to avoid direct blowing and prevent the invasion of cold pathogens. In the season of heavy snow, the wind and snow are cold. Traditional Chinese medicine believes that at this time, yin qi fills the sky and earth, blocking yang qi. It is necessary to dispel cold evil, warm the meridians, warm the body, and prevent diseases Cheng Niang introduced that as the saying goes, "cold starts from the feet". The feet are far away from the heart, the blood circulation is poor, and the subcutaneous fat in the feet is not abundant. Friends with weak physical condition and insufficient qi are prone to cold feet at this time. Foot coldness is actually caused by insufficient yang energy in the body, which cannot warm the limbs. It is important to keep the feet warm, clean, and dry. Soak the feet in warm water every day, and keep the water temperature around 40 degrees Celsius. In winter, there is less sunshine, which can easily make people feel low both physically and mentally. The best way to change one's low mood is to be active, with a moderate amount of sweating and avoiding excessive sweating Cheng Niang introduced that jogging, dancing, Tai Chi, and Ba Duan Jin are all good medicines for eliminating winter boredom and maintaining mental health; It is not recommended for middle-aged and elderly people with weaker physical conditions to participate in fitness activities such as winter swimming. Traditional Chinese medicine believes that at this time, yang energy is hidden, and severe cold will dissipate the body's yang energy, exacerbating the harm of cold and dampness to the human body. In addition, due to the frequent freezing rain during heavy snowfall, exercise should also pay attention to selecting the weather to prevent respiratory diseases. Snowflakes drift, the north wind howls, and the sky and earth are vast... "Whenever heavy snow falls and covers everything, a sense of inexplicable grandeur arises between heaven and earth, and people's emotions become particularly open and bright. In this romantic and poetic season of snow falling and white hair, why not sit around the stove, drink tea and read books, or chat about daily life, and experience the small and genuine beauty in life with your heart.
