The winter solstice is the darkest time of the year.

The winter solstice is the shortest day and the longest night in a year. It's colder because of the short sunshine time. At the same time, there are some ghosts in the saying, so I feel that this day is the most cloudy.

If we divide a year according to solar terms, it means that the solstice in winter is the heaviest day of yin, and we all know that the solstice in summer is the heaviest day of yang in a year, while the solstice in winter is the heaviest day of yin in solar terms. Because on the day of winter solstice, the nights begin to get longer, the days begin to get shorter, and the nights are cloudy, so Yin Qi begins to flourish, and this day is the day when Yin Qi prospers.

Beginning of winter means that it has entered winter, and the snowy day is coming, so winter is the heaviest day of yin. We need to eat jiaozi in the winter solstice in the northeast and glutinous rice balls in the south. Different areas will have different customs, so we need to start preparing cotton-padded jackets and winter supplies.

Old legend

In Zhouyi, the winter solstice is still a good day for self-cultivation, because after the winter solstice, internal heat will lurk, and people without internal heat will be much better for the liver. Therefore, on the solstice of winter, you can eat more foods that are good for your kidneys and liver to keep healthy, thus regulating your body. According to the festival, Ghost Festival should be a day full of yin, and it has been the most taboo day since ancient times.

There are three ghost festivals in China, one is Tomb-Sweeping Day, the other is Cold Food Festival, and the other is Ghost Festival, which is also the Central Plains Festival. However, we say it's cloudy or Halloween. In ancient society, there is a legend that from the first day of the seventh lunar month, the gates of hell will be opened so that dead ghosts can go to earth to meet their relatives.
