There is a tablet in Imperial Tablet Pavilion bestowed by the Kangxi Emperor, on which Temple of Mount Heng Renovation Memorial was inscribed, comprising 279 characters written by the emperor himself. The first sentence reads, Mount Heng is the giant pillar in South. It corresponds to Star Yu Heng of Big Dipper, and is also called Mount Longevity. Mount Heng's another name, Mount Longevity, was thereafter determined by the authority. The original tablet was destroyed in the Cultural Revolution.
