I remember when I was in primary school, you will find these propaganda papers on the streets telling South Koreans of how corrupt their government was and urging them to defect to North. Apparently, North Korea would send balloons filled with these propaganda messages. South would do the same to North.
Then there was a TV show once a year where separated families in North & South re-unite for a holiday. They were separated during the Korean War and the two governments allowed these families to be found and meet for a few days, before they were separated again. They hadn't seen each other for ~30 years so were young and only remembered just a few bits of information. These TV shows made EVERYONE cry.
