What does it mean to have a three-light zone on people who walk at night?

This statement comes from folklore. We can also call it a story. It is said that man is a living thing among the dead, with Yang in it. Together with the sun be the spirit, it is the three light areas. A lamp is on a person's head, a lamp is on his left shoulder and a lamp is on his right shoulder. In a word, it's like three searchlights on a car. Ordinary people can't see the Three Lights Zone, only people in the underworld, that is, the dead, can see it. If the dead come to the dead, they are called ghosts. They are afraid of sunshine, just like Tweety is afraid of honesty. Because the dead are afraid of the sun, they lurk in the dark, trying to kill them and suck their yang, so as to survive.

But "can't you turn back when you leave at night?" A person walking at night may form a figure because of the moonlight. If you look back at your own shadow when walking at night, you may think of what you are afraid of, which will make people feel psychological fear. A superstitious view is that there are unclean things behind you, and those so-called unclean things are actually invented by themselves. In the final analysis, it is an instinct of self-protection for a person to walk at night and be afraid that people or things that don't exist will hurt him.

Now there is a scientific explanation that people will turn right when walking in the northern hemisphere because of the earth's rotation bias. In addition, people's left and right feet exert different forces, and there is no obvious reference when walking on the road at night, so they will go astray and get lost. If you often look behind you, it will aggravate this offset angle and make it easier to get lost.
