고려장

It is a term referring to a legendary Korean custom of abandoning old and sick parents in the mountains to die.

It primarily appears in folklore or stories and was often used as material to impart lessons related to unfilial conduct.

There is little historical evidence that it was actually widely practiced during the Goryeo Dynasty, and most scholars view it as a distorted folktale or a story originating from misunderstanding during the Japanese colonial period.
