Mystery Valley

　　Mystery Valley is one of the great wonders of Tianzhu Mountain, located beneath Feilai Peak. It is hailed as the foremost granite cave secret abode, known as the "Unique Wonder of Tianzhu Mountain." Taoist believers regard it as the Temple of the Primordial Yuan. The valley boasts a highly perilous geographical location, stretching five to six Chinese miles in length. Throughout the valley, massive boulders are interspersed, with deep and treacherous caves. The valley floor hosts 54 caves of diverse shapes, clustered and interwoven. These caves connect to one another—cave within cave, tunnel within tunnel, forming an ever-changing landscape that shifts with every step, shrouded in mystery. Inside the caves are windows, courtyards, gates, stone staircases, and stone railings, resembling a winding corridor that suddenly opens into a bright space. In narrow sections, visitors must crawl on hands and knees; in wider areas, several people can stand side by side. Ancient trees with twisted branches beside the valley hang like iron-wall paintings; inside, peculiar rocks and unusual plants create a fairy-tale-like scene reminiscent of a celestial palace, captivating all who visit.
