"Soksu" is a stone carving of an animal which was placed in front of tombs since the Han Dynasty of China, to chase off evil spirits or inside to stand guard.

The earliest known stone carving of an animal in Korea is the "Soksu" dating from the Paekche period, excavated from the Tomb of King Muryong. This carving, made of tuff, was found placed at the center of the entrance of the tomb leading to the coffin, facing toward outside. With a height of 30 cm, length of 47.3 cm, and width of 22cm, this "Soksu" has an open stubby mouth, a straight nose without any holes on it, indicating nostrils, and eyes and ears on both sides of the nose. The legs are short, and no toes or claws can be seen. The right hind leg had already been broken off when the Soksu was found. On the head, there was a rusty steel horn which looked like a tree branch. It was broken off while the "Soksu" was being moved outside, but it later was restored to its original form. This stone carving was designated as National Treasure No. 162 and is currently kept in the National Kongju Museum.
