Newspapers had big bold headlines announcing Kim Il Sung's death 8 years before he actually dropped dead.
Check your sources, TG.
Great Leader and Eternal President Kim-Il-Sung will never die. He will live on in perpetuity and lead the revolution to smite the imperialist American aggressors.
Finally, another patriot in this thread who hasn't succumbed to the lies and evil of the American imperialists and the counter-revolutionaries. Chairman Kim is in perfect health, and the Eternal President Kim-Il-Sung watches over us, as he was born on Korea's tallest peak from there you can see the entirety of his empire in Korea. Long may the Eternal President reign comrade.
Actually (yes, I'm actually-ing my own joke), the propaganda around KIS was that he was born into a poor family in a small village. He left this village as a young man to avenge the atrocities committed against his family by the occupying Japanese. This is probably the part of the story that's the most realistic and backed up by some level of historical evidence and, to his credit, he played a big part in fighting the Japanese until their surrender to the Allies in 1945.
You're thinking of KJI's origin story with regards to the mountain (DPRK claims he was born on sacred Mount Paektu; records indicate he was born in the Soviet Union).
Legend has it that when KJI was born, a new star took its place in the sky and all of the snow melted before blooming into flowers. When he died, a massive earthquake cracked the ice on the mountain's lake.
Not sure why I paid so much attention in the class I took during my undergrad on the DPRK, but it was SUPER interesting.
