Haituo Mountain is located in the southwest of Chicheng County, Hebei Province, with Chengde in the east, Zhangjiakou in the west, Bashang Grassland in the north and Beijing in the south. Haituo Mountain is also known as the Big and Small Heshan. Two thousand years ago, Wang Xizhong changed the seal character to the official script, and the story of three rejections of First Emperor Qin's official post was taken here. Haituo Mountain is famous for its typical north temperate mountain forest ecosystem. With its varied landscapes and moderately accessible routes, Haituo Mountain has become the home base for outdoor enthusiasts in Beijing.
