The pickled shrimp, a special dish of the Korean nation, has won popularity in Phyongan Province and other areas from olden times.

It emits organic acids including amino acid and special flavor when it has become seasoned, helping digestion.

This dish is now produced on an industrial basis at the Kumsanpho Fish Pickling Factory built in the west coastal area under the leadership of the Workers' Party of Korea to make contribution to the improvement of people's diet.
