In 86, I went to Hainan Island for the first time to visit the ends of the world. At that time, the ends of the world were open. There were no current facilities and parks, but a beach. No one charged. The car could drive directly to the vicinity of the attractions and there were not many tourists. At that time, Sanya did not have many attractions, except for the end of the world, the Dadonghai, Luhuitou, I heard that there is a monkey on the island, maybe the current monkey island. There is a railway on the north side of the Tianya Haijiao attraction, which is the incriminating evidence of Japanese ghosts for looting the iron ore of Shilu Iron Mine. The scenery of the ends of the world is still the same, that is, there are too many people. You can look directly at the magnificent stones of the ends of the world on the observation deck not far away, and look at the Guanyin of the South China Sea from afar. A plane flying from afar roars past from overhead. The tropical plants and blooming flowers in the park are intriguing. Sanya has changed too much.
