It commemorates Kim Jong Il partaking in an effort to plant trees on Changsan with students of the Pyongyang Middle School No. 1 in 1957. He also helped in constructing the Wasan-dong–Ryongsong Road there in May–June 1961 when he was still a student at Kim Il-sung University. Kim Jong Il's activities at the site to "carry out the far-reaching plans of th great leader President Kim Il-song for the construction of the capital and building of Armed Forces" continued into 1962. Kim also guided military exercises of students of the Pyongyang Namsan Senior Middle School and Kim Il Sung University there many times. Taking part in these efforts were some of the first signs of Kim Jong Il rising in political profile thus readying to succeed his father Kim Il Sung as the leader of North Korea.
