Then at his palace, he dug a large pool and piled up three earth hills in it to imitate the circumstances described in the legend. For example, Emperor Qin Shihuang, the first emperor of the Qin Dynasty (221 - 206 B.C.), wanted to live an eternal life and had sent people to look for the magic mountains but they failed. Gods in those mountains had a kind of herbal medicine which would help humans gain immortality.Ĭonsequently, many emperors in the feudal age of China constantly sought those mountains. The story is that once upon a time there were three magic mountains called 'Penglai', 'Yingzhou' and 'Fangzhang' located to the east of Bohai Bay (to the east of China). Beihai Park is said to be built according to a traditional Chinese legend.
