I’d say basically all of them. Information on Korean folk beliefs is so difficult to come by.

But on another note, I have come across the belief in Korean household gods and it is so intriguing. Basically, they are gods represented by small objects like pots filled with grain or paper hung in a specific part of the house. I find very “near” rituals like house gods to be very interesting. But it’s also very difficult to find information on so I wonder if house gods are still practised.
