The theory of "a hundred ghosts traveling at night" in Winter

On the solstice of winter, it is a traditional custom to worship ancestors and sweep graves. According to folk custom, when Pangu opened the sky, it was the winter of solstice. At this time, the genius has just opened, and there is no head yet, and the world travels; Legend has it that at midnight on this day, the yin is particularly heavy. If you stay in the wild, you will see the wonders of ghosts walking at night, so everyone should go home early on Ghost Festival. Therefore, people can't go to the solstice in winter. Of course, this is just a superstition.

The word "hundred ghosts walk at night" first appeared in the stories collected by Uji in Japan-the yogi walks at night and everything is ready. In this form, the Japanese "Talking" has produced a relatively complete description of the works of the nocturnal ghosts, which has penetrated into painting and drama. For example, Shi Yan's "Painting Hundreds of Ghosts at Night" also lists the origin of monsters. Many of them come from China and India.

Extended data:

In winter solstice, although the sun is low and the days are short, the temperature in winter solstice is not the lowest in meteorology. In fact, because there is still "accumulated heat" on the surface, it is usually not very cold before the winter solstice, and the real cold is after the winter solstice.

Because of the huge climate difference in China, this climatic winter is obviously late for most parts of China. The winter solstice marks the beginning of the cold season, and people begin to count nine to calculate the cold days.
