The first time I went to spend 30 yuan to invite a full-time commentator to explain, the beautiful woman's explanation is very detailed, here is the only one in Hainan, connected to the underground river cave, there are many stone flowers, only three places in the country can see, first walk, then go out by boat, 70 yuan ticket also includes the fare, very cost-effective, beautiful scenery, the next time will come again.
