4.3 : The April 3 incident in Jeju Island left a tremendous trauma for the people of Jeju. Looking through Jeju's oral life stories, the incident left the trauma of the violence of the North West Korean Youth Association, an anti-communist group on the Korean Peninsula, and the pain of their lives being uprooted. And they say that the sense of betrayal that the powerful people make them feel by not keeping their promises and living a life labeled as criminals even though they are not criminals is a trauma. We can say that finding a way to treat these people to improve their trauma is a very important task.
