Occasionally, some non-white wall buildings can be seen on the island, but they are also light in color and very few in number. Although it is a volcanic rock island with sparse vegetation, the locals will plant plants wherever possible. As a cliff island, walking on a small road on the side of the cliff, such a landscape can be seen everywhere here not only has the blue water, the sky without clouds is as deep as a sea of blue. Sunshine at the cliff hotel, blowing the wind to admire the blue water, waiting for the sunset, is also a cozy.
