True to the intention of his father Kim Hyong Jik that a man born in Korea must have a good knowledge of Korea, he came to Mangyongdae for learning. One day of January Juche 14 (1925), he received the news that his father had been arrested again by the Japanese police.

He left Mangyongdae on January 22 with a determination to fight at the risk of his life to take revenge on the enemy of his father, his family and the Korean nation.

Thirteen days after his departure, he arrived in Phophyong, Kim Hyong Jik County of Ryanggang Province (then Huchang County of North Phyongan Province), and crossed the Amnok River with a grim resolve not to return before Korea had become independent.

The Korean people are calling the journey, which the President walked with the determination to rescue the country and people from the colonial rule of the Japanese imperialists, the 250-mile Journey for National Liberation.

Since 1975 many schoolchildren of the DPRK have taken part in the expedition of the 250-mile Journey for National Liberation, marching along the route for 10-odd days.

The expedition of the 250-mile Journey for National Liberation which left Pyongyang on January 22 this year will arrive in Phophyong on February 3 through Kaechon, Hyangsan, Kanggye, etc.
