Red Stone Valley Scenic Area

　　Red Stone Valley Scenic Area, commonly known as the Dahebei Primeval Forest, is located in Nanhengzhangzi Village, Dahebei Township, Lingyuan City. The area is named "Red Stone Valley" because most of its rocks are dark red in color. This is a natural ecological scenic area primarily characterized by pristine vegetation landscapes, along with the hilly terrain of western Liaoning. The total area of the scenic zone exceeds 5,000 acres. In 2005, with Nanshan Mountain as the focal point, it was designated as the Lingyuan Qinglong River Provincial Nature Reserve by the forestry department of Liaoning Province. The main peak of Nanshan Mountain, Hongshiluo, once served as a battleground during the Qingping Campaign in the Chinese Civil War.
