Introduction to Qinglong Mountain: The geological structure of Qinglong Mountain belongs to the northern wing of the Songshan Mountains in the Qinling latitudinal structural belt. The east and west veins run parallel, and the different mountains merge together. It stretches for more than 20 miles, with steep mountains, towering peaks, and canyons. Deep and steep. Since ancient times, there have been records of "thousands of rocks competing for beauty, thousands of valleys contending for flowing water", "peaks and ridges standing together, and streams lingering". In ancient times, it was called Huoshan Mountain and Tianling Mountain. Later, because the Northern Song Dynasty chose to build the imperial mausoleum on the side of the mountain, it was renamed Qinglong Mountain according to the feng shui theory of exploration. Song Taizu Zhao Kuangyin named it "the best feng shui treasure land in the world".
