Jung said: "I was protesting, asking for an inquiry to find out the real reason why the ferry capsized. Some foreign tourists took photos of me. At that moment, I felt I was an alien, although I live in this country. All I wanted to know was the reason why the crewmen were all rescued but our children had to die." #

Jung Hye-suk, the mother of Park Sung-ho, a high-school student who died in the ferry disaster, in her son's room in Ansan on April 7, 2015. Jung said: "Good children have died because of adults’ faults. The Sewol disaster taught us about the problems of our society, and adults should make efforts to fix them, although it’s too late. We have to strive to prevent any reoccurrence of this disaster and to build a culture that cherishes human life. Our children didn’t blame society. They tried hard to save each others’ lives and worried about their families. Don’t we have to learn from the efforts they showed in the last minutes of their lives?” #
