The next day, I went to Xiamen University and Nanputuo by bus (just outside the south gate of Xiamen University). Xiamen University suggests going to the Anthropology Museum and Lu Xun Memorial Hall. The scenery outside Nanputuo is very good. Just look at the temples inside. Don't go up the mountain ... you will be exhausted (another thing: there is a botanical garden to see).
On the third day, Xiamen University went out of Baicheng Beach, which was very beautiful and could be taken for a walk. In addition, it is recommended to go to the Garden Expo Park for a day, and it is best to bring your own food and water.
On the fourth day, you can go for a walk around the ring road. There are also zoos, folk villages in Taiwan Province Province, Jingzhou Paradise and Nanputuo in Xiamen. You can also go to the seaside, but it's too cold in winter to be fun.
The above is for reference, thank you!
