Changling is located in the north of Sanyi Village, Yaodian Town, 20 kilometers north of downtown Xi and 20 kilometers east of Xianyang City. 1988, the State Council listed it as a national key cultural relics protection unit. Changling, also known as "Changshan Mountain", is the tomb of Emperor Gaozu Liu Bang and Empress Lv Zhi (Lv Hou).
Changling site is located at the highest place in Xianyang, the former site of Qin Xianyang Palace. From a distance, it looks like a towering mountain, with great momentum. Weiyang Palace is across the river in the south, Jiusan in the north, and Jingwei River runs through the mausoleum area. Overlooking Chang 'an Scenic Area, it has been a famous hub in Guanzhong since ancient times. 1970 to 1976, Shaanxi Provincial Cultural Relics Management Committee conducted a comprehensive exploration of Changling and found a large number of physical remains. Changling is the joint tomb of Emperor Gaozu Liu Bang and Empress Lv Zhi, and the cemetery remains. The cemetery is rectangular in plane, with a length of 1000 m from north to south and a width of 900 m from east to west. In the middle of the western wall, the ruins of the 23-meter-wide city gate were discovered. There is still a rammed earth relic 600 meters long, 6 meters wide and 3 meters high on the ground of the West City Wall. The mausoleum is located in the south of the cemetery, with Gaozu Mausoleum in the west and Luhou Mausoleum in the east, about 250 meters apart. Gaozu's mausoleum is rectangular and 32 meters high. There are six large sleeping halls in the northwest corner, southwest corner, southeast corner and along the south wall of the cemetery.
To the east of Changling is the cemetery, which stretches for 15 miles. According to historical records, Xiao He, Cao Can, Zhang Er, Tian Fen, Zhou Bo and other heroes are mostly buried here. Tang, a poet in the Tang Dynasty, said in a poem: "There is a Gaoling in Changling, where Liu is safe, and only many people are buried." These numerous and continuous tombs, from a certain point of view, reproduce the grand occasion of the early Han Dynasty.
Porcelain pieces engraved with seal scripts of "Changling Dangdong" and "Changling Dangdong" were unearthed near Changling. 1968, a "Queen Seal" seal was unearthed near Changling, which may be Lv Hou's seal. Changling is a key cultural relic protection unit in Shaanxi Province. Changling is "120 paces from east to west, 13 feet high, in the north of Wei River, 35 miles away from Chang 'an". At present, the east-west length at the bottom is 153 m, the north-south width is 135 m, the top is 55 m, the north-south length is 35 m, and the height is 32.8 m, which is close to historical records.
