At the same time, Li Lushi also actively participated in armed anti-Japanese activities. 1932, he entered the "Korean Military Academy" run by the Military Committee of the China National Government, and used the infantry tactics and special combat mission skills he learned at school to fight against the Japanese colonists. As time goes by, the hope of recovering the motherland seems to be getting smaller and smaller. At this time, he will use poetry to motivate himself and gain greater confidence.
The Wilderness published by 1942 actually became his last work. In the poem, he hopes to sow the seeds of songs in the wilderness so that people can enjoy singing after recovery. He used this prophetic poem to emphasize that the independence of the motherland is not a dream, but will become a reality. Li Lushi himself died in the prison of the Japanese Consulate General in Beijing in June 5438 +0944+10.
