Holding a group for a half-day tour, the time is a bit rushed, but it is still worth seeing. Linjin Pavilion has a freedom bridge and locomotive for returning prisoners of war. The third tunnel can walk 268 meters, plus the slope of the tunnel has more than 1,000 meters back and forth, which is quite a test of physical strength. The observation deck can see the two villages and the higher flags set by the two Koreas in the DMZ. The landing platform is the symbol of South Korea's desire for reunification. After reunification, it will be the first train station to North Korea. It's good to listen to history and feel the atmosphere of war.
