Wuling was originally located in the north of Xianyang City, starting from Xingping City in the west, east to Gaoling County, north to Jingyang County and south to the north bank of Weihe River. It is about 40 kilometers long from east to west and 13.5 kilometers wide from north to south, with a total area of about 500 square kilometers. Because of its thick original soil layer, open terrain and excellent natural scenery, it was regarded as a treasure trove of geomantic omen by the rulers of past dynasties and became a royal mausoleum area. Tang Shunling and Qin Xianyang ruins are all here; Nine emperors in the Western Han Dynasty 1 1 were buried here. These tombs dug holes in the ground and lined up in the direction of Zheng Guoqu. They are magnificent, tall and majestic, and are known as the "pyramids" of China. Among them, five mausoleums, namely, Gaozu Changling Mausoleum, Huidi Anling Mausoleum, Jingdi Yangling Mausoleum, Wudi Mausoleum and Zhao Di Ping Ling Mausoleum, were established as cities and counties, hence the name "Wuling Yuan".
Wulingyuan is an undeveloped underground history museum with as many as 17 national and provincial key cultural relics protection units, which shocked China and foreign countries. According to experts' research, Wulingyuan's "Pyramid" is comparable to the Egyptian Pyramid in historical sequence and cultural connotation.
