Introduction to Dongtian Blessed Land: The so-called Dongtian Blessed Land is a place worthy of the residence of gods, which means Fengshui treasure land or fairyland. In ancient times, there were 72 Dongtian Blessed Land and 36 Blessed Land in the country, and Wulei Mountain occupies one of them. At the end of the Yuan Dynasty, Zhang Dui, the editor of the Hanlin State History, resigned from office and retired to Wulei Mountain. He expanded the temple on the mountain, promoted Taoist culture, and personally inscribed "The most famous mountain in southern Chu". From then on, Wulei (Immortal) Mountain became famous, and the temples built were "hundreds of miles away, and all the counties can see it." After learning about it, Emperor Shenzong of the Ming Dynasty named Wulei (Immortal) Mountain the "Blessed Land of Cave Heaven".
