The plot of watching the liberation of the laboring people in the world is the fourth scene of the opera Honghu Red Guard: the solo part of Han Ying when his mother and daughter meet in the dungeon, which is the aria of the play. It is the main aria that can reveal the inner world of Korea and Britain most profoundly in the whole opera; it has a strong dramatic color, and shows the indomitable revolutionary spirit of Korea and Britain and the optimistic revolutionary sentiment that firmly believes in the victory of the revolution.
