渤海
According to the "Classic of Mountains and Seas", the mountain is located at the eastern end of Bohai Sea. According to the pre-Qin mythology which retells the legend of Xu Fu presenting a memorial to the Qin Emperor in order to seek for the elixir of life, there are three godly mountains which are found in the Bohai sea where immortals reside; these mountains are Penglai, Fāngzhàng (), Yíngzhōu (). Other islands where immortals reside are called Dàiyú () and Yuánjiāo ().
