The opera was adapted from a revolutionary drama "The Sea of Blood", an immortal classic masterpiece created by President Kim Il Sung during the anti-Japanese revolutionary struggle in the 1930s. The drama deals with the indiscriminate massacre of the Korean people by the Japanese imperialists. Its heroine gets gradually awakened and comes out to the road of the revolutionary struggle.

Leader Kim Jong Il unfolded a far-reaching plan to bring about a turn in the field of opera through the adaptation of the drama to opera and energetically led the work. Therefore, Korean-style revolutionary opera "The Sea of Blood" was created in 1971 with the introduction of verse-songs, pangchang, dance, stage arts, orchestral music and others.

On its basis, the "The Sea of Blood"-style revolutionary operas "The Flower Girl", "A True Daughter of the Party" and "Tell O Forest" were created in a short span of time and became known to the world.
