In ancient times, the site of Ganquan Palace was valued, and the palace was built here in Qin and Han dynasties because Ganquan area was famous for its dangerous terrain in ancient times. Fan Ju's "Warring States Policy" describes: "The kingdom of the king has Ganquan and Taniguchi in the north." Ganquan Mountain is the outpost of Xianyang. In order to resist aggression, Qin Shihuang built the Imperial Palace on the site of Ganquan Palace, and built a straight road from Ganquan to Jiuyuan in Inner Mongolia to facilitate armament. Ganquan Palace site is a summer resort with high and cool terrain. Qin Shihuang went to the Guanglin Palace in Ganquan, not only to escape the heat, but also to deter the Huns.
During the Western Han Dynasty, the site of Ganquan Palace was second only to Weiyang Palace in Chang 'an. According to historical records, after the expansion of Ganquan Palace in the first year of Emperor Wu of the Han Dynasty, "Nineteen miles a week, 120 steps in the twelve palaces" ("Guan Zhong"). According to another record, the site of Ganquan Palace "compared with palace buildings, every official has a mansion" (Parentheses). This shows the grandeur of the palace. Han Shu Suburb Sacrifice Records records that Emperor Gaozu went to Ganquan Palace: "Emperor Gaozu came five times, Wendy came 26 times, Emperor Wudi came 26 times, Emperor Wudi came 75 times and Emperor Xuandi came 25 times. It has been 20 years since the first year of the Yuan Dynasty." According to Zi Jian, Emperor Taizong visited Ganquan Palace in the 20th year of Zhenguan (646). The Qin and Han Dynasties followed the Tang Dynasty, and emperors traveled to and from the ruins of Ganquan Palace because many important political decisions were made here, such as meeting governors, entertaining foreign envoys, preventing foreign invasion and safeguarding the frontier.
