How much does it cost to travel from Shenzhen to Xiamen for three days?

Day 1 Nanputuo-Xiamen University-Shapowei (literary model, excellent photography)-Yunshang Xiamen (landmark building)-Zhongshan Road-Ferry (when the weather is good, you can see the whole Gulangyu Island from a distance).

Day2 Visit Zeng Cuo An Village Village-Cycling around the island road (with good scenery along the way)-Hu Lishan Battery (which is not interesting to me personally)-Xiamen University Baicheng seaside-live in Gulangyu Island.

Day 3 Gulangyu-Return trip.

Nanputuo, Xiamen University, Zhongshan Road, Huandao Road and Xiamen University Baicheng are all free, and tickets for Gulangyu Island are 35 round trips. As for how much you are going to spend on food, drink and accommodation, it depends on your own economic strength. Xiamen is mainly a literary and artistic tourism, where people spend money on eating, drinking, housing and transportation, and do whatever they can.
