Located in the north shore of Beiliao Village, Penghu, Kuibi Mountain is commonly known as "Turtle Mountain", because the close seashores were rich in turtles. Another possible reason for its name is that the mountain looks like a turtle lying on the beach if viewed from the sea, hence the name, just like Turtle Island is named for its turtle shape. It can be found that Taiwanese would like to give name to places directly based on the visual appearance. Later, because the "Turtle Mountain" is indecent, people gave it a more artistic name called "Kuibi Mountain", which is now generally accepted.
