Introduction to Wild Pineapple Island: Half of the island is artificially planted mangroves like tea trees. It is full of vitality and stretches as far as the eye can see. It is even difficult to distinguish where is the island and where is the sea. Half of the island is a dense forest of wild pineapples, which is eerie and dark. The breath-taking roots of the wild pineapple tree grow two meters high outside the soil. The roots are connected to the branches, and the roots are intertwined and strangely shaped. The scientific name of the wild pineapple tree is Pandanus tree. It is a small tropical tree of the Pandanaceae family and belongs to the mangrove family tree. It is a wild sand-fixing plant. Its fruit is like a pineapple, but it is extremely hard and almost inedible, so the locals call them wild pineapples, and the island gets its name from the tree.
