Introduction to the Stone Frog: There is a stone frog on the sea surface of Golden Beach, with its head east and tail west, looming with the ebb and flow of the tide. It is called the "invisible stone frog". A poem from the Qing Dynasty said: "The island is graceful and graceful, and the water is pouring out from the sky. The sound of the tide is like a roar shaking the mountains. It is suspected that the general is coming with a crowd."
