He had a divine birth
On North Korea's revered Baekdu Mountain, a double rainbow and a bright new star are said to have heralded the birth of Kim Jong-il in 1942, which is one of the most interesting facts about Kim Jong-il.
In contrast to other biographies, the official North Korean account of Kim Jong-il's life claims that he was born at a guerrilla base camp on Mount Paektu, the highest point on the Korean peninsula. It also claims that his birth was heralded by fortunate omens like the appearance of a double rainbow in the sky. Kim's birthday is supposedly celebrated around the world, but North Koreans, many of whom are purportedly facing starvation, are not aware of this.
One of Kim's mother's friends, Lee Min, claimed that word of Kim's birth first traveled via radio to an army camp in Vyatskoye; Kim and his mother did not return there until the following year. According to reports, his mother passed away in 1949 during giving delivery. When World War II came to a close and Korea reclaimed its independence from Japan in 1945, Kim was just four years old. That September, his father went back to Pyongyang, and in late November, Kim went back to Korea on a Soviet ship, arriving in Sonbong. The family relocated to a garden and pool-equipped former Japanese officer's residence in Pyongyang. In 1948, Kim's brother drowned there.
