The vocational public high school in Jeonju's Deokjin District where the scenes of the fictional Guun Hi-Tech High School (Episode 2) were filmed. Unlike the other locations clustered around Daegu, this site sits in the Honam region; its workshop blocks and broad grounds shaped the trade-school atmosphere on screen. It is an active school, so visits during term should be avoided.
