The incident of "the intervention of the steam country in returning to Liao" shows that Japan's strength is not enough to keep pace with the great powers. As a result, after the war, Ito Hirofumi's cabinet put forward the date of "sleeping and tasting courage" and formulated the "post-war management" plan with the main content of expanding the army and preparing for war. They strongly feel that Japan has pushed out China in North Korea, but it is facing a stronger and fiercer Russia than itself. In order not to let his achievements on the Korean peninsula go to waste, and to keep pace with European and American powers in international affairs, Ito Bowen led Japan to start a new struggle.
