Introduction to the Demilitarized Zone: After the Korean War, the North-South Military Demarcation Line was adjusted on the basis of the 38th Parallel, and two kilometers on each side of the temporary military demarcation line were designated as the Demilitarized Zone. Every plant and tree in the DMZ is "strictly protected". Over the past 50 years, it has become a sensitive area where North and South Korea dare not cross. Wildflowers are in full bloom on the roadside, and various trees are in disorder, absolutely "original". It is reported that the ecological environment here is very well protected, and some people call it an "ecological treasure house."
