Piljang is a craftsman who makes brushes using basic materials such as fur and bamboo. The brush is made of a cone by collecting the animal's fur and fixing it to the brushstrokes. It mainly uses animal hair, such as goat hair and weasel hair.

The brush-making function is the same everywhere in the country, and not only is the number rapidly decreasing recently, but the tradition of Korean brush-making may be cut off due to the influx of Chinese brushes and materials (chlorine hair).

The value of designation is significant in that it is necessary to preserve the traditional function of making brushes using goat hair and bamboo in Gangwon-do.

Since settling in Chuncheon in 1985, Park Kyung-soo has played a role in preserving and inheriting Korea's traditional brush-making functions by using traditional techniques throughout the entire process, such as straightening, removing oil, shaping, tying brush straws, and applying brush strokes.
