A friend and I want to go to Gulangyu Island in Xiamen next year. Is it safe to go on a self-guided tour?

Hello, this summer vacation, I will travel to Gulangyu Island on my own with my sister and my mother, who are the same age as you. If you are two people (the above is better), just don’t be afraid. My mother disagreed and asked her to go together. If you want to spend a week there, you can save about 4,000 yuan; if you have to spend more, it will cost more than 8,000 yuan. I recommend you to go to the family hotel: Nana Coast Family Hotel or Yue Boutique Hotel, both are good. You can take the sightseeing bus on Gulangyu Island (if you have enough funds) and go around the island for a week. Look at the scenery on the island! Or take a boat around the island, this is a must! Because there is a legend among the locals: if you go around the statue of Zheng Chenggong, you will definitely succeed! Before going to Gulangyu Island, you have to understand that there are no cars there, you have to walk! If you plan to live in Gulangyu Island permanently, you should also go to Xiamen to have some fun, otherwise it will be very boring! What is worth recommending in Xiamen is: the tandem bicycle on the beach! You and your friends can go riding together! A must-eat in Xiamen is seafood! Attractions on Gulangyu Island: Aberdeen Back Beach is a fun place to visit, especially at night when the sea breeze blows. There are the most attractions next to the Sea Garden Hotel, including Sunlight Rock. Although when it comes to Gulangyu Island, it is not considered to have been to Gulangyu Island without climbing Sunlight Rock. To be honest, it's better not to go. (If you don’t have enough funds) The tickets there are very expensive and there are no attractions. Just climb up and then climb down! Be sure to buy local pies in Gulangyu Island, they are delicious! Have a nice trip! (No copying at all)
