A community on a slope in Busan is famous for its colorful and unique artworks. In fact, the tragic story behind it is a tearful story. The refugees who had gone through war fled here and settled down. The whole settlement is a step-by-step arrangement of the front houses without concealing the view of the back houses. It reflects the unique architectural virtues. This inheritance interacts with each other. The barren settlements that live in harmony with the local artists and college students have made great efforts to give the village a chance to regenerate with bright colours. Therefore, they have won the reputation of Machu Picchu in Korea. Regrettably, time-limited and intimate guides lead us to visit the best scenic spots to take pictures during limited visits, although it has become a hot spot of tourism, Gancun Cave. The community still inherits the traditionally low-key color of folk houses and exterior walls without a trace of publicizing that residents live as before, even cats do not pay attention to visitors'Street exterior wall stairs, doors and windows. Only then can the colorful murals be seen, just like the Chinese costume under the plain face of Gancun Cave, which was thought to be inaccessible in the old mountains and forests, originally located in the foothills near the West cave of Busan. It's also very convenient for the subway to transfer to the bus. I still have no chance to visit Gancun Cave again.
