A few things I learned about when I went to Hawaii. 1. Afraid of boats polluting the seawater, all planes are going back and forth on several islands, and fishing is not allowed. 2. The island formed by the volcanic eruption has no sand, but the sand that comes back is transported. 3. There are a lot of Japanese people who come to visit and live in the local area. 4, look at the weather forecast, every day is rain. It's all raining constantly. Often hang in the sky. Also called island. 5. The U.S. troops stationed there are dedicated golf courses.
