Living in a cruise ship at sea, sleeping until ten minutes before setting off for the surprise hole. After a quick wash, I took the boat and floated away, and the surprise hole was in a wide bay. After arriving at the bay, I climbed a mountain road to the viewing platform of the surprise hole. The whole landscape can be seen on the platform. The bird's view is broad. The surprise hole is quite big. The tour route does not go back. Left in and right out. The hole is decorated with color lighting effects and has three huge cave rooms. The cave was cool, except for stalactites and stalagmites, and a limestone body shaped by "cauliflower."
