1. After the Opium War, China became a semi-colonial and semi-feudal society, and the powers divided their spheres of influence in China. Especially on the eve of World War II, Japan launched the September 18th Incident on September 8, 193 1, and occupied Northeast China. In the following years, it continued to erode North China. 1935' s "north China autonomy movement" made the front line of Sino-Japanese confrontation from the border between China and North Korea.

Second, after the battle of Lugouqiao, Japan began a full-scale war of aggression against China. This matter has a great influence. Before this war, the Japanese attitude towards China changed obviously, so the battle of Lugouqiao became a landmark event.

3. After the Battle of Lugouqiao, both China and Kuomintang issued statements and started an active resistance movement. In particular, the remarks made by the Kuomintang government about the open war of resistance in Lushan Mountain, and the change of the attitude of the China National Government at that time was also an important reason for promoting Lugouqiao to become the flashpoint of the Sino-Japanese War.

4. The Ministry of Education of China has changed the eight-year war of resistance to fourteen-year war of resistance, counting from September 18, 193 1.
