There is no coherent main line here, and there are no characters involved with each other. Each story is a completely independent and unrelated horror and strange incident.
There are supernatural red hijabs, resurrected paper dolls, shadows that can kill people, running water mats to extend life, and phone calls that should not be answered in the corridor at midnight...
All stories form a closed loop of their own, one after another, all taboos passed down from generation to generation among the people.
Some people don't believe in the rules and take risks, some are soft-hearted and provoke evil spirits, and some are in a dead end out of curiosity.
Every experience is a brush with death.
The whole story is extremely scary when you think about it, and there are no related foreshadowings. If you open any chapter, you will be faced with a bone-chilling horror.
Note: Believe in science and avoid feudal superstition. This is purely fiction.
