Changgeuk (Korean classical opera) is a variation of Pansori. Unlike a Pansori singer who plays multiple roles, each Changgeuk singer plays only one character in a story.
And have you heard about the story of Sim Cheong? The story of her father's regaining eyesight shown in this clip is the climax of the whole story. It is very touching, so I couldn't but shed some tears while watching it...
I hope you like it, too!
