1, Ciba
Playing Ciba is a custom in the light snow solar terms in the south. In ancient times, Ciba appeared as a sacrifice in all parts of the south. And making Ciba can be done from the day of light snow until years ago.
I remember that when we were young, we lived in a rural yard. Once the light snow solar term came, every household began to prepare for making Ciba. Because making Ciba is a heavy manual work, it is done by several families together, and everyone * * * produces materials and * * * works together. In the end, everyone will share it. So it is very lively and fun to make Ciba this day. This kind of happiness can only be understood after childhood experience.
2, kill the pig, eat soup
Killing pigs and eating soup is an important folk custom with a long history in rural areas of southwest China. As long as the light snow has passed, the temperature will drop a lot. At this time, rural residents will also start to kill pigs and prepare meat for the New Year. However, the most important activity of Killing Year Pig is to eat soup.
People who grew up in the city may not understand what it means to eat soup. On the day of killing Year Pig, some friends and relatives are usually invited to help. After the Year Pig is killed, the owner will select some meat and cook it into delicious food to entertain and thank everyone. Everyone sat around, warming themselves and eating steaming soup, which added a lot of warm atmosphere to the cold winter.
Meteorological change
Light snow is a solar term reflecting precipitation and temperature, and it is a solar term with high frequency of cold wave and strong cold air activity. The light snow solar term indicates that a relatively stable meridional circulation has been established in East Asia. When the Siberian low pressure or trough moves eastward, there will be large-scale cold air heading south, which will bring large-scale windy and cool weather.
The light snow in solar terms is not necessarily related to the light snow in the weather. The meaning of "light snow" in solar terms is different from that in daily weather forecast. The light snow solar term is a climate concept, reflecting the temperature and precipitation. The "light snow" in the weather forecast refers to the snow with less snowfall intensity.
Meteorologically, it is called "light snow" when the horizontal visible distance is equal to or greater than 1000 meters, the ground snow depth is less than 3 cm, and the snowfall in 24 hours is between 0.1-2.4 mm.
