Traffic to the island is tough. It takes about three hours to sail. The sea is so rough that it usually gets seasick. Now it is said that there is a passenger liner from Shipu to Yushan Island. We went by charter boat at that time. The conditions are difficult and slightly dangerous. Yushan Island is suitable for sea fishing. Other facilities are general and living conditions are poor. It's good to eat seafood at the fishermen's house. There's nothing else to eat. You can swim in the sea in summer and see the stars in the evening. No more water in other seasons. The conditions for swimming in the sea are also poor. There are no beaches and many sharp reefs. We should pay attention to safety.
