《史记·八书·封禅书》
封禅既毕，秦始皇继续东行到海上游览，一路祭祀名山、大江河以及八神，向仙人羡门高等祈求福佑。
於是始皇遂东游海上，行礼祠名山大川及八神，求仙人羡门之属。
After the feng and shan ceremonies were completed, Emperor Qin Shihuang continued to the east to tour the sea, offering sacrifices to famous mountains, great rivers, and the Eight Gods, and seeking blessings from immortals and Taoist masters.
