The book "Shu Yi Ji" says: "The Jiao man is the Quanxian, also known as the Quanke. The Jiao people come out of the South China Sea, and the Quan Xian hides and weaves the yarn. It is called Dragon yarn, and its price is more than a hundred gold. It is thought that it will not get wet when it enters the water. There is the Dragon Thread Palace in the South China Sea, and the place where the Quan Xian weaves the yarn is as white as frost."
