2. Sain-am: This is a huge rock forming a steep cliff on the west side of Mt. Dokjol eight kilometers away from Tanyang, Chungchong Pukdo. Nearby flows a river along which also stand a fantastic formation of rocks that towers like a colossal folding screen. There is a small Buddhist hermitage, called Chongyon-am, built at the foot of the cliff. The valley, named Unsonkukok, that runs along Sain-am abounds in scenic spots apart from other scenic sites that exist in the Tanyang area. The rock was named Sain-am by Im Je Kwang, a country chief during the reign of King Songjong of the Yi Dynasty, because the place was a favorite resort for rest and recreation of Wu Tak, a scholar of Chinese classics of the late period of Koryo, while he was serving in an official post called Sain.
