Hawaii has always been one of the most unique administrative regions in the United States: the only state in the tropics, the state that officially joined the United States at the latest, and the state that has no territory on the American continent. Many characteristics of Hawaii are quite different from those of the United States. Due to the geographical distance, there are huge differences between Hawaii and the United States in many aspects: they are used to wearing flip-flops instead of sneakers, providing some leftovers for guests to take home after parties, and always taking rice as an important side dish. These habits are almost hard to find in America. As an "alternative" of American culture, "Hawaiian characteristics" are often talked about by people.

The main body of Hawaii is composed of Hawaiian islands, including 19 larger islands and other nameless islands, which are basically formed by volcanic activity. Located at the "crossroads" of the Pacific Ocean, it is the hub of air and sea transportation in Asia, the United States and Oceania and has an important strategic position. Among them, Honolulu is the main line and important port of the Pacific route.
