Which is more beautiful, Haikou or Xiamen, and which is more suitable for traveling?

Xiamen was the first place to be promoted. Although Hainan is now said to be an international tourist island, it has just started. In another five to ten years, I will definitely promote Hainan. Of course, if you want to travel, I recommend Hainan, because compared with Xiamen, Hainan is more short of people and has more development prospects. Xiamen is mature and the absorption rate of new talents is low.
