《太平广记·卷三·神仙三》
王母说， 昔日玉帝清虚元年时，三重天上的太上道君下到世间，观察天地四方，勘测河流海洋的长短和山岳的高低，立起了天柱使大地稳定，安置了五岳山脉使八方平衡。他还建造了昆灵仙宫让仙人们居住，在蓬莱仙山建了馆舍让得道的真人聚集在一起，把水神安置在极阴的河流源头，安顿太帝住在扶桑国的山丘。
王母曰： 昔上皇清虚元年，三天太上道君，下观六合，瞻河海之长短，察丘山之高卑，立天柱而安于地理，植五岳而拟诸镇辅，贵昆陵以舍灵仙，尊蓬丘以馆真人，安水神于极阴之源，栖太帝于扶桑之墟。
Wangmu said, In the first year of Emperor Yuqing's reign, the Supreme Daoist of the Third Heaven descended to the mortal world, observed the four directions of heaven and earth, measured the length of rivers and oceans, and the height of mountains and ridges. He erected the pillar of heaven to stabilize the earth, established the Five Sacred Mountains to balance the eight directions. He also built the Kunling Immortal Palace for the immortals to live in, and built a hostel on Penglai Fairy Mountain for the enlightened real people to gather together, and placed water gods at the source of the extremely yin river, and settled Taidi on the hills of Fusang country.
