Changhai County, located at the junction of cold and summer in China, has a special continental shelf structure, and there are often cold and warm air currents from north to south at the bottom of the sea. The exchange capacity and self-purification capacity of seawater are better than other sea areas, and the nutrients are updated frequently and richer. The turbulent ocean current creates the unique elasticity and firm taste characteristics of sea cucumber in Changhai. At the same time, because the sea cucumber is in the open deep sea, it is always in motion, so it grows slowly, but it accumulates enough nutrients and has high quality.
