Turtle Island National Park was established to protect the declining breeding grounds of turtles threatened by human life, with only more than 20 rooms on the island, and to try to preserve the completely primitive living conditions and space for turtles and other wildlife, Every day, tourists from all over the world have to book very early in advance to have the honor to visit here. The third time I came to Shandagen, I wanted to book the room at the time. This time I booked Turtle Island 3 months in advance. It was not easy to book in China. When I came to the pier, it was the exclusive pier of Turtle Island. It was not the public pier of many boats. Only Turtle Island's own boat was waiting for the arrival of guests here. There was only one boat every day, so I got up early and followed the car to come here.
