It takes only one day to travel in Xiamen. How to play is more appropriate?

I lived directly in the city (near the ferry) the night before and went to Gulangyu by ferry at 7: 30 or 8: 00 in the morning. If it's just the scenery, you have to work harder. It is estimated that it will take 2-3 hours to visit the island all the way. Then decide for yourself whether to eat snacks on the island or go back to the city. Go straight back to the city in the afternoon, and then go to Nanputuo and Xiamen University. Nanputuo can spend half an hour to an hour at most, and then go to Xiamen University on the side to have a good stroll. Go straight back to the hotel after shopping. Go directly to the pedestrian street for dinner in the evening, find that snack street to eat, and stroll around while eating, by the way. Well, it's absolutely hard for you to wander around all day! Go back to the hotel to sleep and leave the next day!
