On a cloudless summer day, my friend and I drove to the lovely border city maps. The first stop was the maps of Sunlight Mountain. We just heard that Sunlight Mountain is beautiful. Today, we saw it and it was well-deserved. It was really beautiful. Standing on the mountainside, you can see the opposite North Korea. South Yangyang City (Figure 9). Tumen are border port cities, also very historical, more rich Korean culture, the city style is very good, is a clean and tidy city.
