2. Unbong Technical High School (Incheon)
The most representative when it comes to high schools with the biggest iljin population. In 2009, a video of one of the students getting into a fight heated up the online community. They have a separate 'transfer student killer', whose job is to beat up any and every transfer student who enrolls in the school. One of the schools with the most school violence/fights in the nation. Also the school of former F.T. Island's Oh Wonbin. Students are known for harrassing students of other neighboring schools for money.
