How can Ryan get to Beiji Island?

There are no hotels on the island, they are all private, people's houses. It's the landing room. There are several floors, and each floor is separate. There are still regulations. If you are with them, you should eat there. If you go there, you should bring a toothbrush and a towel. If you don't provide it, you have to buy it yourself. You can take a boat at the south gate. There is no time limit. Looks like chartered flight. I don't know what 80 is, and I forgot.
