What is the legend about the location of Empress Wu Zetian's graveyard? This must start with the construction of Ganling. Ganling is located on Liangshan Mountain, 6 kilometers north of Ganxian County, Shaanxi Province, and 76 kilometers away from the ancient city of xi 'an. It was built in 684 AD, and it took 23 years for the project to be basically completed. Liangshan is a naturally formed limestone peak, with three towering peaks, the highest in the north, with an altitude of 1047.3 meters, and the lower in the south, with an east-west direction. At that time, people called it "Nitou Mountain". Looking from east to west of Ganling, Liangshan is like a woman lying on her back, with the north peak as the head and the south two peaks as the chest. People often say that it is a wonderful symbol of Empress Wu Zetian. The geomantic master (Mr. Feng Shui) in the Tang Dynasty thought that Liangshan was very beneficial to the hostess. Therefore, Wu Zetian chose Liangshan as her husband Tang Gaozong and her "eternal domain" after a hundred years. After Tang Gaozong's death, Wu Zetian asked Yuan Tiangang and Li, famous magicians in the ruling and opposition circles at that time, to choose the site for the emperor. They traveled around Kyushu respectively, and when they came back, they all said that they chose Liangshan in Tuo County (now Ganxian County).
Wu Zetian sent envoys to inspect. At the top of Liangshan Mountain, Yuan Tiangang said that he buried a copper coin here, and Li said that he ordered an iron nail here. When digging, Li's nails just got stuck in the square hole where Yuan buried copper coins, and everyone present applauded in surprise. So Wu Zetian chose the mausoleum site in Liangshan, which is now Ganling.
