It is a primitive Island recognized by the World Organization. So the islanders can't change anything at will. There are only about 380 people on the island, and there are no universities. Visiting villages by Buffalo cart is very unique. Listening to the explanations of the grandfather of the old residents, singing local songs on the tri-stringed piano, slowly enjoying the original ecological buildings, plants and imagining the life of the local people. There are many stars in the night, and they are very beautiful. It's only a long journey. You need to take an hour flight from Naha Airport to Shiyuan Island, and then change to a cruise ship for 10 minutes to Zhufu Island.
