Haixinshan is an island in the center of Qinghai Lake. It is dominated by grassland and has a lotus nunnery. Several nuns and practitioners practise on the island. There are many legends and miracles on the island. It is said that every winter, nuns wait for the lake to freeze and then hike across the Qinghai Lake to reach the shore. After preparing for one year's supplies, they return to the island and never leave the island for another year. To climb the Haixinshan Mountain, we can only wait for the ice in winter to hike or drive to the island. Traffic mode: Xining Passenger Station takes a shuttle bus to Shadao, Bird Island or Jiangxi Gully. From any of these three points, it can reach Haixinshan Island on foot for about 30 kilometers. The island is short of fresh water and supplies. In addition, it is very dangerous to cross the ice surface. Do not wear ice claws to avoid causing the ice surface to break.
