Beginning of winter is a seasonal solar term, which means that it has entered winter since then. Stand still, build the beginning; In winter, everything will be collected in the end. In the dead of winter, yang retreats to yin, life closes, and everything is harvested. "Spring grows, summer grows, autumn harvests, and winter stores", and winter is the season to enjoy a bumper harvest and recuperate. Beginning of winter is one of the "four seasons and eight festivals" in ancient China. In some places in ancient China, sacrifices, banquets and other activities were held at the beginning of winter as important festivals to celebrate.
3. Traditionally, "beginning of winter" is the beginning of winter, and the dry climate with little rain in autumn gradually passed, and it began to transition to rainy and cold winter climate. After beginning of winter, the sunshine time will continue to shorten, and the height of the sun will continue to decrease at noon. Because there is still some energy in the heat stored on the surface, the temperature is gradually decreasing in early winter, but it is not very cold. As time goes by, strong cold air frequently goes south and crosses Nanling, and the weather is getting colder and colder. In the north, it is already very cold before winter begins.
4. beginning of winter said that winter begins from now on. Traditionally, winter begins with 24 solar terms "beginning of winter". In early winter, the sun reaches the longitude of 225 degrees, and the earth is at declination-16 19. The height of the sun in the northern hemisphere becomes smaller, the daylight time becomes shorter, and the amount of solar radiation obtained in the northern hemisphere becomes less and less. However, there is still some energy in the heat stored on the surface in the second half of this year, so it is not very cold. In winter in Meng, when there is no wind on a sunny day, there is often sunny, warm and comfortable "Xiaoyangchun" weather, and there is a folk saying of "Xiaoyangchun in October". In some parts of the south, it is generally not very cold in early winter, but with the passage of time, cold air frequently goes south and the temperature gradually drops. The northern region is very cold from winter to spring, and the climate change of several solar terms in winter is not obvious. Snow is the main feature of northern winter.
In some areas of southern China, it is always warm as spring during the winter solstice and the light snow festival, so that some fruit trees mistakenly think that spring has come and bloom for the second time. The so-called "August is warm and September is warm, and there is a small spring in October". In the dead of winter, the so-called "March 9 cold" is usually when it is not too cold before the winter solstice. Starting from the winter solstice, every "nine days" is counted as a "nine", the first nine days are called 19, the last nine days are called 29, and so on. The coldest period in a year is 39 days. From the beginning of the winter solstice solar term, it began to enter the "three or nine days." Strong cold air frequently goes south, the temperature drops suddenly and the weather is cold. Therefore, the solstice winter is really cold winter.
