I suggest going to Xiamen Science and Technology Museum. (Address: Xianyue Road Culture and Art Center opening hours: Tuesday-Sunday 9: -17: ) And there are museums, libraries and art galleries next to it, with a strong cultural atmosphere.
There is a commercial street near the Science and Technology Museum, including Pizza Hut and KFC, and there is also a local restaurant where you can eat Xiamen specialty snacks such as fried oyster, frozen bamboo shoots, fish ball soup, fried noodles and spiced strips.
Do you have any recommendations for a 5-day free travel route in Qingdao?
