Hopefully this is on topic enough and catches the eye of Kevin and other historians.

Last night the Discovery Channel had a show on The First Emporor of China.

In this show they mention the Peng Lai Islands as the home of the 8 Immortals and an elixer of immortality. But, no one could ever find them.

Things I know about the term "Pong Lai"

It's an old term for the island of Taiwan, hence Shiye Shi's choice of it for our system.

There is a town on the northen tip of the Shandong Peninsula name "Peng Lai"

Is there a connection between "Peng Lai" the mythical islands and the town of "Peng Lai" in Shandong?

How did Taiwan become known as "Pong Lai/Peng Lai" and when?
