Wu Weiye, a famous poet in the early Qing Dynasty, once said in Volume 10 of "Meicun Collection": "Sea cucumbers are produced in Denglai Sea." In his famous poem "Sea Cucumbers", the poem goes: "Make well soup to wash in advance, It is late to enter the Dingdang. It is forbidden to be in the North Sea. The food can be cooked in the south. Don't distinguish the insects and fish species, but don't use medicine to nourish the rest of your life.
