1. Xianling is located in Xumuyuan (now Sanyuan County, Shaanxi Province) in Weibei Plateau. Xu Mu Yuan was also called Wanshou Park in the Tang Dynasty, and some historical materials were also called Bailuyuan. Xu Mu originally belonged to the Beishan Mountains, a branch of Luliang Mountain, and was the most important branch of the "Northern Dragon" among the "Three Dragons" in the eyes of China ancient scholars. However, Xumuyuan is only 500 meters above sea level, which is naturally not imposing compared with the elevation of Jiusan, where Zhaoling is located. However, although Xu Muyuan has a flat terrain, his vision is still quite broad. Looking at Chang 'an from a distance also makes him relaxed and happy. Archaeological data show that the Xianling Mausoleum is located in the middle of Xumuyuan, 4 kilometers west of the Mausoleum is the Duan Mausoleum of the first generation Sun Wuzong Li Yan, and 6.5 kilometers west is the Zhuang Ling of Li Yan's eldest brother, Li Zhan, Tang Jingzong. History of Geomantic Treasures was finalized by Emperor Taizong and Li Shimin.
2. Ganling is located in Liangshan, 6 kilometers north of Ganxian County, Xianyang City, Shaanxi Province. This is the tomb of Tang Gaozong Li Zhi and Wu Zetian.
Ganling was built in the first year of Tang Guangzhai (684) and in the second year of Shenlong (706). Adopting the construction method of "taking the mountain as the mausoleum", the mausoleum area is modeled after the capital Chang 'an. In addition to the main tomb, there are seventeen small tombs buried in Ganling with other royal family members and heroes. Ganling is the best preserved of the eighteen tombs in the Tang Dynasty, and it is also the only tomb in the Tang Dynasty that has not been excavated. ?
196 1 year, Ganling was announced by the people of China and the State Council as the first batch of national key cultural relics protection units.
