What scenic spots do you choose for a three-day tour in Hainan?

I have been studying and working in Hainan for six years. According to my personal experience, I suggest that you can omit the next day's trip. Yalong Bay on the second day and Tianya Haijiao Scenic Area on the third day belong to the coastal category, which is a bit repetitive. Just go to one place. Diving to see personal hobbies. The weather in Sanya is not bad these days, with the highest temperature of 30 degrees. Diving is not cold, but people who have no foundation usually don't adapt to diving because of earache, and finally feel uncomfortable. I don't know if the performance of the program is performed by a celebrity artist, but I can also remove it.
