As the heavy snow solar term enters, the cold cold of the year has also begun. Heavy snow is the 21st solar term of the year and the third solar term of winter. Following the Xiaoxue solar term, the weather became even colder, so the snow became heavier.

"Cold before frost, cold after snow." Entering the heavy snow solar term, the cool cold of the year has also begun.

Heavy snow, the 21st solar term of the year, and the third solar term of winter. Following the Xiaoxue solar term, the weather became even colder, so the snow became heavier. "The Seventy-Two Sessions of the January" says: "The great thing is to be prosperous. At this point, the snow is full." Scientists say that snow is solid precipitation caused by the water vapor in the sky condensed. Climatologists have divided the four levels of snowfall: light snow, medium snow , heavy snow and blizzard for snowfall. The heavy snow in the solar term is not strictly quantified, but is just a description of temperature and climate change trends.

Each solar term is divided into three phases. During the heavy snow solar term, the first time is "the thorns (hédàn) do not roar". The squid is the legendary cold bird, which stops calling because it is cold. When I was a child, my father told me a story. The cold bird was very lazy. He didn't listen to the persuasion of magpie . He refused to make a nest on a sunny day, and finally frozen to death on a cold night. When I grew up, I realized that this story originated from a fable in the late Yuan Dynasty and early Ming Dynasty - saying that the cold bird was colorful in midsummer. I am also proud and claim to be more beautiful than a phoenix. In the severe winter, the feathers fall off, like a little broiler with plucked hair, comforting yourself to "just live" - ​​this is how the idiom "just live". Later, experts told me that the cold bird is not a bird, but a kind of gliding mouse, scientifically called compound-toothed squirrel . This really surprised me. The second time is, "the tiger begins to get along." During the heavy snow solar term, the yin energy is approaching its extreme, but it is strong and declining, and the yang energy is also quietly sprouting. The tiger feels these tiny yang energy and begins mating, starting the journey of life. "Tiger" has always been a symbol of courage. Gao Qi, a politician in the Ming Dynasty, said, "Although the tiger is fierce, it is still happy, and it is rampant only in the mountains", which means "a harsh government is more fierce than a tiger." When I was a child, I herded cattle and said, "I was fucking ammunition and arrows all over my waist, and I was not afraid of tigers bullying yellow calfs." In fact, there were no tigers in the Dabie Mountains at this time, but the power was still there. The third time, "Lili is coming out", and new buds emerge from Malan flower . Li, scientific name , Malin , commonly known as Malanhua. "The golden rays are ridges in the country, and the horse orchids bloom all over the Tingzhou." The dreamy lilac color is the favorite of many people.

The so-called "heavy snow" means that it started to snow heavily at this time point in the Central Plains. The solar term is a probabilistic statistic, not that it is snowing heavily on time in the Central Plains every year at this time. Just like the plum rain in the summer of the Yangtze River , the number and length of the year varies. In my hometown, near the Central Plains, , the Dabie Mountains, it was common for heavy snow to block mountains in winter in the past - more than fifty years ago, I was born on the heavy snow solar term, a heavy snowy morning. Many years later, my family also described the snow that was said to be very rare to me with interest. However, now my hometown often doesn’t see any snow at all for many years, let alone heavy snow to block the mountain. Therefore, heavy snow may be the solar term that has changed the most in ancient and modern times. This is still the case near the Central Plains. People who are in Jiangnan now want to see heavy snow, which is really harder than seeing solar and lunar eclipses and meteor shower . In the winter of 1632 AD, in West Lake, Hangzhou, "three days of heavy snow, the sound of people and birds in the lake were gone." Ming Dynasty writer Zhang Dai thus left the famous article "Hidden snow at the pavilion in the middle of the lake". This kind of scene should have been rare at that time and is even more rare now.

Heavy snow not only freezes to death the pests and diseases in the soil, but also stores water for the earth, so it is beneficial to crops. Chinese people have long known the benefits of heavy snow to farming, so they are full of feelings for snow, which is the so-called "auspicious snow indicates a good harvest." A good harvest is very important, which means that most people in this world can fill their stomachs. When I was a child, my father helped my neighbors write Spring Festival couplets, and he liked to write "The mountains and rivers are beautiful, the scenery is beautiful, and there are many happy events in life and the years are prosperous." Only when there is a prosperous year can there be a life expectancy and a prosperous country and a peaceful country. Famine is often a prerequisite for social unrest. This is true for the farming society, and this is still true for the post-industrial society. Until now, the Central Document No. 1 of every year is based on agriculture, rural areas and farmers, which shows that the importance of food is unparalleled.

As the saying goes, "It's cold before frost, and cold after snow." Entering the heavy snow solar term, the cold cold of the year has also begun. This kind of coldness has different feelings for different people. Tang Dynasty , especially in the early Tang Dynasty and the prosperous Tang Dynasty, people were full of vitality and full of energy. Severe cold can better demonstrate the strength of life. "The grass withered and the eagle's eyes were fast, the snow was gone, the horse's hooves were light", "I want to chase the light rider, the heavy snow was covered with bows and swords", "I am alone in the straw hat, fishing alone in the cold river snow", "Suddenly it is like a spring breeze coming, thousands of pear blossoms blooming", "The long clouds in Qinghai are dark in the snow mountain, and the lonely city looks at Yumen Pass from afar", "I want to cross the Yellow River ice blocking the river, and I will climb the Taihang snow all over the mountain", "The yellow clouds are in the sun, and the north wind blows the geese and snow all over the snow", "Yanshan snowflakes are as big as mats, and pieces blow down Xuanyuantai"... full of optimism. It was an optimistic era, that was an optimistic era. (Han Kesheng)
