Gwanak Mountain, which is located at the boundary between Anyang City and Gwacheon City, is famous for its beautiful harmony of pine trees and rocks. Nowadays, most of the rocks in Gwanak Mountain are suffering. Some people have curved his or her name and address, or drawn pictures on the rocks, including precipitous cliffs of rock. Gwanak Mountain has become black and blue. However, because of a superstition, in which people believe they will be able to pass exams or enter universities, people are writing their names into the rocks.
