Your plan is very good. Food suitable for dinner is suggested to be a food stall, if you dare to eat seafood.

The scenic spots in Xiamen can be found online, so I don't need to go into details here. Moreover, the scenic spots in Xiamen are relatively concentrated, so there is no need to deliberately arrange the route.

On the first day, you can go directly to Zeng Cuo An Village to arrange accommodation. It is a few steps away from Huandao Road, which is also close to the bathing beach, opposite Gulangyu Island, and there are Zhongshan Road, Hulishan Fort, Xiamen University and Nanputuo nearby. If you have time, you can go to Wuyuanwan Water Town for half a day and get in touch with the black swan.

You can stay in Jimei the night before the trip. There are many budget hotels here. Jimei Xuecun is worth visiting. Have you heard the story of Mr. Chen Jiageng? Jimei is closest to Xiamen North Station and Gaoqi Airport, and it takes 2 minutes to arrive.

If there are children traveling with you, recommend some places that children like: Gulangyu Underwater World, Jimei Lingling Circus, Antoinette Dream World, Xiamen Science and Technology Museum, etc.
