Haixin Mountain, commonly known as Huxin Island, was called Xianshan or Longju Island in ancient times. It was named "Quezontorohai" and located in the south of the center of Qinghai Lake, about 30 kilometers away from the South coast. It is a major tourist attraction of Qinghai Lake. The island is 2.3 kilometers long in East and west, 0.8 kilometers wide in North and south, and has an area of 1 square kilometer, which is like a shell. The top of the mountain is tens of meters above the lake and about 3300 meters above sea level. The granite and gneiss of the mountain system are milky white. It's sunny and beautiful. Looking from a high distance, Haixinshan is magnificent as snow waves. Haixin Mountain has elegant environment, green grass, thin clouds in light area, fresh water and clear spring, and pleasant scenery. The White Pagoda of the ancient temple is hidden in the mountains. It's like walking into fairyland. The ancients once had a poem praising - "a piece of green wave floating snow, no one knows is Haixinshan".
