Boundary Island（also known as Shengcun Island），From a distance, the island looks like a horse’s saddle with its highest point rising to 99M above sea level. Local fishermen call the island "Beautiful Woman Island"or "Guanyin (the Buddhist Goddess of Mercy) Island". Boundary Island’s mountains are covered with coral trees (Erythrina). According to Chinese folklore, long ago a shrieking parrot caused kapok to fall from the local coconut palms. This landed on the coral trees and gave them their unique blossom. When the flowers bloom it looks as if the entire mountains are covered in flames, a truly amazing sight to see.
