based on 1,109 reviewIt is the abbreviation of demilitarized zone, which means demilitarized zone. It means that North and South Korea set up a military buffer zone within their respective territories with 38 degrees north latitude as the boundary, and each side retreated 2 kilometers to draw a military buffer zone. At the Dorasan Observatory, you can see the surrounding urban landscape. The Freedom Bridge was the place where North and South Korea returned prisoners at that time. The iron fence at one end of the bridge was hung with ribbons, and people wrote on them their beautiful wishes for unification. The Third Tunnel and Dorasan Railway Station are also highlights of the visit.
