Introduction to Moon Island: Moon Island, also known as the Ring Island, is named after its shape like a crescent moon. It is located above the opposite bank of Lingyun Cave. The pavilions and corridors on the island are all made of bamboo and wood structures, extending from the water's edge to the hillside. Directly above the bluestone mountain gate is an inscription by Lu Mai, a famous calligrapher and former vice president of Xiling Seal Society. The 20 waterside villas with red tiles and white walls have a unique style.
