Last night, the frost was clear and the fluff was cold, with red leaves covering the steps. After tasting the fragrance of orange and pomelo, enjoying the ginkgo yellow, people were still amazed by the beauty of late autumn. Early winter has quietly arrived. November 7th this year is the winter day. At this time, the sky is vast, the mist is misty, the wind is gradually rising, everything is calm, nature is simple and simple, embracing simplicity and guarding simplicity. Farewell to the abundance of autumn, welcome the profoundness of winter, and the 'hiding' of all things begins from here on. Autumn has already set and winter is approaching. Beginning of winter is the 19th solar term among the 24 solar terms and also the first solar term of winter. Every year around November 7th in the Gregorian calendar, when the sun reaches 225 degrees longitude, it enters the Beginning of Winter solar term. The "Collection and Interpretation of the Seventy Two Houhou of the Moon Order" records: "It was established at the beginning, and in winter and at the end, all things were collected. In northern China, during this time of autumn, crops are mostly harvested and sun dried, and "grain is stored in the warehouse and vegetables are stored in the cellar"; Some animals also go into hibernation, preparing to start a long hibernation. All things in the world gradually quieted down, savoring the long winter in their hidden slumber, and replenishing their energy for the flourishing of next spring. Lidong is the first solar term of winter, but it does not necessarily mean the arrival of winter. China has a vast territory, and there are significant differences in climate between the north and south. Meteorology believes that it is considered winter when the daily average temperature is below 10 degrees Celsius for five consecutive days. According to this standard, during the beginning of winter, most northern regions of China have entered the threshold of winter, while in many southern regions, the rich autumn colors are still continuing, but the trend of temperature decline is becoming increasingly evident. During the period from the beginning of winter to the light snow season, although "autumn deepens and gradually enters winter", whenever the wind and sun are beautiful, warm weather often appears in the south. Therefore, people call October in the lunar calendar "Xiaoyangchun", which is warm and comfortable, making people feel relaxed and happy. There are three seasons in the beginning of winter: the first season is when the water begins to freeze, the second season is when the ground begins to freeze, and the third season is when the pheasant enters a large water and becomes a mirage. After the beginning of winter, water usually turns into ice, from dew, cold dew, white frost, to water beginning to ice. The different forms of water reflect the trend of temperature changes; The weather is getting colder and the earth is starting to freeze; The term 'pheasant' refers to large birds such as wild chickens, while 'mirage' refers to large clams. In ancient times, it was believed that birds such as wild chickens became large clams after the beginning of winter, corresponding to the phrase 'birds entering large waters become clams' during the Cold Dew period. Why did ancient people have such wonderful imaginations? This is because after the beginning of winter, the weather gradually gets colder, and large birds such as wild chickens are less active. However, by the water's edge, many clams with shell lines and colors similar to wild chickens can be seen. Therefore, ancient people imagined the scene of wild chickens entering the water and transforming into large clams, full of innocent interest. Autumn has already passed, and a new winter is approaching. The four seasons have turned to the last season, indicating that the year is coming to an end. After the beginning of winter, the sunshine duration will continue to shorten, the noon sun height will continue to decrease, and the weather will gradually become colder. Precipitation in most areas will significantly decrease, and the forms of precipitation will begin to diversify, including rain, snow, sleet, hail, ice particles, etc. When there is strong cold air, it also snows in the Jiangnan region. At the beginning of winter, the yang energy is hidden, plants and trees wither, and the activities of all things tend to come to a halt. The metabolism of the human body is also at a relatively slow level. At this moment, the Yin Qi is extremely strong, and cold is the Yin evil, which is most likely to harm Yang Hu Xin, Deputy Chief Physician of the Cardiovascular Department at Beijing Hospital of Traditional Chinese Medicine affiliated with Capital Medical University, introduced that the main "collection" in winter is to maintain good yang energy, avoid excessive consumption of yang energy in the body by external yin and cold qi, and prepare for the coming spring. To welcome winter, worship winter, and supplement winter, there is a way to start winter, which is known as the "Four Rites" along with the Beginning of Spring, Beginning of Summer, and Beginning of Autumn. In ancient times, it was one of the "Four Seasons and Eight Festivals". In ancient China, the beginning of winter was not only a solar term, but also an important festival. On the day of the beginning of winter, the emperor will lead civil and military officials out of the suburbs to set up altars for worship, perform the ritual of "welcoming winter", and give winter clothes to the courtiers and show respect for the lonely. In some areas, there is a custom of ancestor worship among the people, praying for good weather and abundant harvests in the coming year. The people are also accustomed to preparing winter clothes at the beginning of winter to defend against the upcoming winter cold. According to the Qing Jialu, during the Qing Dynasty, every winter, scholars and officials would pay respects to their elders and elders at home and go out to pay respects to each other. Men, women, children, and elders would change into new clothes and bow to each other, known as "winter worship". Spring plowing and summer plowing, autumn harvest and winter storage. Winter is the season to enjoy a bountiful harvest and rest. As the saying goes, 'Start winter to replenish winter, replenish empty mouth', people who have been working hard for almost a year finally welcome winter leisure. On the day of the beginning of winter, people reward themselves with delicious food and resist the cold, which is called "nourishing winter". On the day of the beginning of winter, different regions have different food customs. In Nanjing, there is a saying that goes "half a onion a day, bring the wind to your legs in winter". Old Nanjing people believe that eating raw onions after the beginning of winter can resist the dampness and coldness of winter and reduce the occurrence of diseases; In the Chaoshan region, there is a saying that "eating sugarcane at the beginning of winter does not cause pain to the teeth". At this time, sugarcane has already matured, and eating it can protect the teeth, prevent overheating, and also have a nourishing effect; In the Minzhong region of Fujian Province, it is popular to boil grass root soup during the beginning of winter. This health soup is made by boiling some traditional Chinese medicine grass roots that are "medicinal and edible" together with chicken, duck, rabbit meat, pig trotters, pig bellies, etc. It has the functions of tonifying the kidneys, stomach, and strengthening the waist and knees; In the north, people are accustomed to eating dumplings on the day of the beginning of winter. The beginning of winter is the turn of autumn and winter seasons, and dumplings are eaten during the "jiaozi" season, symbolizing the transition between old and new and praying for good luck in the coming year. The food for 'supplementing winter' varies from place to place, but most of them are aimed at enhancing physical fitness and resisting the cold winter Hu Xin introduced that winter corresponds to the kidneys of the human body, and the key to supplementing in winter is to nourish the kidneys. At this time, it is advisable to eat more black kidney tonifying ingredients, such as black beans, black sesame seeds, black rice, black fungus, black dates, etc; It is not advisable to eat salty food in daily life to prevent damage to kidney essence, and it is also important to eat less cold tasting foods such as crabs, shrimp, watermelon, etc. Does nourishing winter mean eating meat in big bites? No, it's not. When taking winter tonics, one should first identify their own constitution, and according to their own needs, nourish and protect the positive qi of the five organs in a targeted manner, avoiding blind and excessive tonics. "Hu Xin explained that traditional Chinese medicine believes in" tonifying deficiency, but actually purging it. "Deficiency syndromes are divided into four basic types: qi deficiency, blood deficiency, yang deficiency, and yin deficiency. People with qi deficiency usually have short qi, lazy speech, easy fatigue, excessive sweating, and are prone to colds. Winter tonics should mainly focus on strengthening the spleen and tonifying qi, and can eat more yam; People with blood deficiency often suffer from dizziness, insomnia, and pale complexion. They can eat more ass hide glue, jujube, etc; People with yang deficiency are usually more afraid of cold, and their hands and feet are often cold in winter. These people can warm up yang and dispel cold by eating more beef and mutton, drinking soup, and other methods in winter; People with yin deficiency constitution are mostly thin in body shape and prone to internal heat. They are not suitable for eating lamb or other spicy and hot foods to supplement their diet. They can eat more duck meat, lilies, etc. to replenish fluids and nourish yin. Despite the decreasing temperature and increasingly cold weather, the scenery at the intersection of autumn and winter can be described as magnificent, with orange yellow and orange green, colorful frost leaves, and various colors colliding and interweaving, making people intoxicated. The lotus pond that fell into the water is withered everywhere, and the west wind gradually turns into the north wind The beginning of winter marks the beginning of winter, and the northwest wind begins to emerge. The northwest wind is the new wind, the new wind is north, and the new wind is north; Shuo is also the beginning, and Shuo day is the first day of every month. The northwest wind, also known as the "not surrounding wind", "the northwest is not surrounding, only hidden". In the hidden beginning, the northwest wind is the breeding of the spring breeze. The period from the beginning of winter to the beginning of spring the following year is commonly known as the "Winter March". Hu Xin introduced that the Yellow Emperor's Inner Canon believes that "in the third month of winter, this is called closed storage, with water and ice on the ground, no disturbance to the yang, sleeping early and waking up late, and waiting for sunlight... This is the way to nourish storage in response to winter qi." That is to say, winter health preservation should avoid the cold and store warmth, go to bed early and wake up late appropriately, and strive to fall asleep before the hour of midnight (23:00 to 1:00). The hour of midnight is when yang qi is weakest and yin qi is most abundant. At this time, sleeping can nourish yin the most, and the latent yang qi in the human body is not disturbed. Normal people usually sleep for about 8 hours a day, and those who are weak and prone to illness should increase their sleep time appropriately. At the same time, try to avoid going out for morning exercises too early and wait until dawn before getting up. Cold pathogenic factors are the main pathogenic factors in winter, and it is important to pay attention to preventing them after the beginning of winter Hu Xin introduced that during the beginning of winter, there is often widespread cooling, coupled with heating in the north, the temperature difference between indoors and outdoors increases. Middle aged and elderly people have poor vascular elasticity and poor tolerance to environmental temperature. When exposed to alternating cold and hot stimuli, their blood vessels contract throughout the body, increasing the burden on the heart and easily causing coronary artery spasm, angina pectoris, myocardial infarction and other diseases. Therefore, it is necessary to pay attention to keeping warm and cold. After the beginning of winter, is collecting all things no longer suitable for exercise? No, winter exercise should also pay attention to 'hiding'. Due to the decrease in temperature, the speed of human metabolism slows down, so exercise should not be too intense at this time. In addition to paying attention to warm-up and stretching, there should be three changes. "Hu Xin introduced that during the beginning of winter, the exercise time should be changed. The temperature in the morning and evening of winter is lower, and low temperature can easily induce cardiovascular and cerebrovascular diseases. It is recommended to postpone winter morning exercise to after 9 o'clock; The type of exercise needs to be changed, and it is recommended to choose indoor exercises with smaller ranges, such as indoor skipping rope, climbing stairs, doing yoga, practicing Tai Chi, etc., which can help improve the flexibility and balance of the body; The goal of exercise should be changed. We don't pursue sweating profusely, as long as we feel a slight warmth in our body, we have achieved the goal of exercise. Spring is born, summer is long, autumn is harvested, winter is hidden, seasons do not stay, everything is orderly. Winter is a store, a hope, a dormancy, and a hope. The phenological change of in one year, withers and thrives once each contains infinite longing for a better future. Let's open our arms and embrace the warm winter sun. (New Society)
