Daoism teaches that all things in the universe have their own spirit (god). In ancient times， people thought that supernatural beings ascend to Heaven， or dwell in far-off beautiful places. During the Warring States Periods， those who sought immortality imagined that there are three divine mountains in the Bohai Sea (渤海)—Penglai， Fangzhang， and Yingzhou (蓬莱、方丈、瀛洲). Those mountains are the habitations of immortals and that the drugs of immortality can be found there. According to later Daoist teaching， the habitations of immortals came to include The Ten Continents and The Three Islands (十洲三岛). The continents include Zu (祖洲)， Ying (瀛洲)， Yan (炎洲) and seven others. The islands are Kunlun (昆仑)， Fangzhang (方丈) and Penglai (蓬莱).
The Ten Celestial Caverns (十大洞天) are residences of Daoist immortals on the famous mountains on this earth. They include Wangwu (王屋山洞)， Weiyu (委羽山洞)， Xicheng (西城山洞)， Xixuan (西玄山洞) and six other caverns.
The Seventy-Two Blissful Lands (七十二福地) are also located on famous mountains on the earth， and all managed by perfect beings in accordance with the orders given by deities.
These include Mt. Jun (君山) in Dongting Lake (洞庭湖) and Mt. Damian (大面山) close to Chengdu， Sichuan Province.
