Tumen River
The history of conflict in the area (examples include incidents during the Battle of Lake Khasan) was alluded to in singer Kim Jeong-gu's song 'Tearful Tumen River (눈물 젖은 두만강)', which became an ode to families separated by such tragedies and by defections during the Korean War. The humanitarian crisis along the Tumen River was dramatized in the 2010 dramatic feature-length film.
