What is the Rain Water solar term and how did it come about?
Introduction: Everyone knows that the 24 solar terms in our Chinese traditional culture have been called the fifth greatest invention of China. They embody the diligence and wisdom of the ancients. Rain Water is the second solar term among the 24 solar terms. So, do you know what the Rain Water solar term is? How did this solar term come about? Please see the analysis below for specific details! The first month of the lunar calendar is an important month. Let us pay attention to the traditional festivals and solar terms in the first month and have a good start of the month. Rainwater is the second solar term among the 24 solar terms. Around February 19th every year, when the sun's ecliptic longitude reaches 330 degrees, it is the Rain Water of the 24 solar terms. At this time, the temperature rises, the ice and snow melt, and the precipitation increases, so it is named Rainwater. The Rain Water solar term usually starts on February 18th or 19th and ends on March 4th or 5th. Rainwater, like Grain Rain, Light Snow and Heavy Snow, is a solar term that reflects precipitation phenomena. "Collected Explanations of the 72 Seasonal Changes" states: "In the middle of the first month, heaven produces water. The beginning of spring belongs to wood, but what produces wood must be water, so the Rain Water follows the Beginning of Spring. And when the east wind thaws the ice, it dissipates and turns into rain." This means that around the Rain Water solar term, all things begin to sprout and spring is about to arrive. For example, the "Book of Yi Zhou" records the phenological phenomena such as "the arrival of wild geese" and "the sprouting of grass and trees" after the Rain Water Festival. The rain started and the amount of rain increased gradually. The meaning of the Rain Water solar term is the beginning of rainfall and the gradual increase in rainfall. In the Yellow River Basin, the origin of the 24 solar terms, the weather before the Rain Water is cold, but you can see snowflakes flying, and it is difficult to hear the sound of rain. After the rain, the temperature generally rises to above 0 ℃, with less snow and more rain. However, in the southern region with a warm climate, rainfall is not uncommon even in the dead of winter. During this period, the average temperature in most parts of southern my country is above 10℃, peach and plum buds are in bloom, and cherry flowers are in full bloom, indicating that we have indeed entered spring in terms of climate. Except for a few years, the frost season ends here. Now is the right time to graft fruit trees and plant trees. After the dry winter, South China is often hit by spring drought all year round, especially in the western part of South China where "spring rain is as precious as oil." In addition, cold waves can cause severe temperature drops and snowstorms, which are extremely harmful to old, weak and young animals. All of these require special prevention. The period of severe cold and snow has passed in most parts of the country. It has started to rain and the rainfall has gradually increased, which is conducive to the greening or growth of overwintering crops. We should speed up the field management of overwintering crops and make preparations for spring plowing and sowing, such as seed selection, spring plowing and fertilization. During the 15 days of the Rain Water solar term, rain comes and grass and trees sprout. We walk from the sixth day of "Qijiu" to the second day of "Jiujiu". "On Qijiu, rivers open, on Bajiu, swallows come, on Jiujiu plus 19, oxen are everywhere". This means that except for most areas of the northwest, northeast and southwest plateaus which are still in the cold winter, many other areas are undergoing or have completed the transition from winter to spring. Under the urging of the spring wind, rain and water, the vast rural areas are beginning to show a busy scene of spring ploughing. However, during the rainy season, cold air activities in the north are still frequent and the weather is changeable. Since we are talking about the frequent cold air activities in this season, we cannot fail to mention what people often call "spring cover". This is the health-preserving principle of dressing proposed by the ancients based on the characteristics of climate change in spring. In early spring, the yang energy gradually rises, the climate becomes warmer, and people gradually stop wearing cotton clothes and start wearing thin clothes. However, the coldness in the north has not yet ended, and the temperature fluctuates greatly. Although the rainy season is not as cold as the cold winter months, the skin pores of the human body have become relatively loose, and the resistance to wind and cold will be weakened, making it easy to be susceptible to evil and get sick. Therefore, it makes sense to pay attention to "spring covering" at this time. This unpredictable weather can easily cause people's mood swings and even anxiety, affecting their physical and mental health. It is even more harmful to patients with high blood pressure, heart disease and asthma. In order to eliminate these unfavorable factors, in addition to continuing to practice spring cover, we should adopt active mental adjustment and health-preserving exercise methods. Keeping your emotions stable plays a very important role in your physical and mental health. After the rain, the spring breeze brings warmth, and pathogenic bacteria and viruses are easily spread by the wind, so infectious diseases often break out in spring. Everyone should protect themselves, pay attention to physical exercise, enhance resistance and prevent the occurrence of diseases. During the Rain Water solar term, the ground's moisture gradually rises, and dew and frost appear in the mornings. Therefore, in view of such climatic characteristics, dietary adjustments should focus on regulating the spleen and stomach and dispelling wind and dampness. Because the climate is relatively cold at this time, you can take appropriate supplements. Honey, dates, yam, white fungus, etc. are all suitable supplements for this solar term.
