Is Beisakan in ancient Xianyang a mountain?
Wulingyuan is located in the north of Xianyang City, Shaanxi Province, starting from Xingping City in the west, reaching Gaoling County in the east, Jingyang County in the north and the north bank of Weihe River in the south. 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. Wulingyuan is regarded as a treasure trove of geomantic omen by the rulers of past dynasties because of its high original soil thickness, open terrain and excellent natural scenery, and has become a royal mausoleum area. Tang Shunling and Qin Xianyang City sites are located in Wulingyuan; 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.
