suggestions for buying specialty products: directly search for online shopping such as Haorenzhen/Xiaguyu/Xiamen specialty/Xiamen pie/Gulangyu specialty/coconut cake, or directly buy it on Gulangyu Island, such as Minchuchun, Jin Dian Shijia, Xiaguyu, Haorenzhen, etc., including pie, dried fish, dried meat, floss, preserved meat, scallops, abalone, etc. You can ask for help to mail or send it to the hotel when you buy a scenic spot. I heard it's free. It is said that the competitive pressure is great now, and Xiamen's specialty products are similar in other places except the airport.
If there is enough time and the scenic spots are considered as specialties, it is suggested to take a one-day trip to Gulangyu Island (including Riguangyan, Xinzhuang Garden and Gulangyu Island in the south), Nanputuo-Xiamen University-Guaipo, Jimei Garden Boyuan-Aoyuan-Jimei University, and then you can visit Tongan Film and Television City and Dalai Island Shop when you have time.
