Fishing sea cucumber is a dangerous job and a highly technical business. Not only must you be able to bear hardships, but you must also have rich experience in underwater operations. Ordinary people may even die if they go down.

To catch sea cucumbers, you should first put on a diving suit, then put on a diving mirror, tie the hole in front with a leather hose, then put on flippers and a respirator, and the diver dives into the water with a net bag filled with sea cucumbers in his hand. Fishermen need to dive to a depth of seven or eight meters below the sea surface, and the net bag can only be filled at one time. The average fisherman can catch five or six hundred Jin a day, and the efficient fisherman can catch several thousand Jin.
