Story of Hyojabawi

A mountain called "Suribong," which appears as an eagle about to fly, is located in Samhangol valley in Balsan-ri, Chucheon-si. There are many rocks and falls with legends due to the beautiful scenery including rocks of fantastic shapes. There are 9 small temples in Suribong, one rock under one of such temples tells of a sad story.

Once upon a time, an old father and a young son lived on this rock, but the father was very sick, so that the young son had to beg for food or starve. Therefore, the son scrounged around the temples to feed his father. One day, the monks of 9 temples gathered into one place for a meeting since this boy came to beg for food at every meal.

One monk said, "Since this child comes to each of the 9 temples at every meal, he would get food just from one temple if all of us eat at the same time." Then, they agreed to start a meal when the temple located in the center ring the bell. The next morning, as the bell rang out, meals were served at all 9 temples at the same time. Each temple gave him food because they thought he came to only their temple, but a boy still appeared at all 9 temples and begged for food from them. Then the monks discussed how to get rid of the rock where the old father and his young son lived. One monk came to the rock and hit it with an axe. After it struck blood spread out from the 9 temples while the father and his son disappeared. Later tiny bugs invaded all over the 9 temples which all then burned down. Now at this place only the sites of the 9 temples and the rock remains. Since the son served his father with filial piety, people call this rock Hojabawi, meaning a "rock of filial son." Some also call it "Giteukbawi" since the son was praiseworthy (the word "Giteuk" means "praiseworthy).
