On summer nights, near Gu Ye Lane, sometimes a green landscape appears, which is vague. Legend has it that people become ghosts after death. Ghosts are afraid of light They dare not come out during the day and come out at night. In the cemetery or wilderness, sometimes there will be green or light blue flames, jumping infinitely. What's more strange is that it will follow people, stop when it's time, and run when it's time. Superstitious people say that this is the time of "ghost fire", and "ghost" goes out to light the road at night. They also said what kind of ghost lights appeared in the "ghost fire". In Zhai Yizhi written by Pu Songling, a writer in Qing Dynasty, there is often a saying that there are fewer people and more ghosts.
"Ghost fire" originated in the summer night, suburban wilderness or ancient tombs. Sometimes there are blue-green flames, which are vague and uncertain. In the countryside, it is said that people will become ghosts after death. Ghosts are afraid of light and dare not come out during the day, but at night. In cemeteries or wilderness, sometimes there is mass at night. As a matter of fact, the saying of jack-o'-lantern is not unique to China. Phosphorus was discovered in 1669 by Brandt, an alchemist in Hamburg, Germany. The original meaning of "phosphorus" in Mullah is drought "ghost fire".
"Ghost fire" is actually a superstition. In fact, "jack-o'-lantern" is a substance called "bisphosphonate", which is produced by the decay of animal carcasses. It is a phenomenon of "spontaneous combustion" in the air. Bisphosphonates are light and float in the wind. When people walk by, it will float with people. So it is the decay of animal carcasses that produces phosphides, one of which is called bisphosphonates. In air, a kind of "spontaneous combustion" phenomenon.
So it's easy to explain that there will be blue flames near the cemetery. Ghost fire is just a folklore. It is essentially a blue flame produced by phosphorus combustion.
