비봉산 형제봉이 서북쪽으로 죽장리를 거쳐 연악산을 향해 이어지다가 떨어져 나온 곳으로, 예부터 평야가 비옥하고 농사가 잘되어 솥 안의 밥과 같다 하여 정식(鼎食)들이라 불렀다.
It is a place where Bibongsan Hyeongjebong Peak was connected to Yeonaksan Mountain through Jukjang-ri to the northwest and then fell off, and since old times, as the plains were fertile and well cultivated, it was called Jeongsik Plain because it resembles rice in a pot.
