Guan Suo Ridge — Imperial Calligraphy Pavilion

　　   Guan Suo Ridge — Imperial Calligraphy Pavilion is located to the east of Guanling Autonomous County and is a Guizhou Provincial-level Cultural Relics Protection Unit. It is the first checkpoint of Guan Suo Ridge. In the second year of the Kangxi reign in the Qing Dynasty (1663), an imperial plaque inscribed with “Key to Yunnan and Guizhou” was hung on the gate tower, hence the name “Imperial Calligraphy Pavilion.”
