The air tickets to Gulangyu Island were all booked on May 1 day, but the weather forecast even reported heavy rain. There are instructions from friends there. Thank you~

If you can only travel on May Day, then I suggest you don't refund your ticket. Because holiday Gulangyu is crowded with people, if it rains, maybe there will be fewer people and it will be more comfortable to play. If it is sunny, you can't see anything when you go, only people. . . .

Gulangyu Island in rainy days actually doesn't affect your play. Gulangyu Island is called the International Architecture Museum, which mainly focuses on the human landscape. Walking around with an umbrella is actually quite emotional, but it is not convenient to go to the seaside. However, there is nothing to see on the beach of Gulangyu Island. If you want to see the sea, you have to go to Sanya. After all, Gulangyu is just offshore, and there is no such feeling of blue.
