Difference? Korean? Western?

The shin in shinhwa are a breed apart. They are the gods who live in the heavens and more or less rule over the earth. The other shin (also called chapshin, chap meaning "various" or "miscellaneous") live on the earth and interact quite regularly with humans; these chapshin are a product of Korean folk religions. Ghosts, faeries, guardian spirits, and even what would be considered monsters in the West are all described by the term chapshin. Interestingly, ghosts and monsters in Korea do not hold the same place of horror and dread as they do in the west; there are, in fact, no truly evil chapshin. A ghost may of course take revenge on someone who has done them wrong, but the Western vampires, ghouls, zombies and the like--fearsome monsters evil to the core--have no counterparts in Korea. Chapshin often act as judges or guardians, punishing the evil and rewarding or protecting the good.
