China experienced a difficult and tortuous struggle for 14 years from 193 1 to 1945 when the Japanese signed the surrender. Among them, 1937 Lugouqiao Incident is the boundary, and the first six years are the period of local anti-Japanese war, and the last eight years are the period of national anti-Japanese war.

Extended data:

Eight-year Anti-Japanese War and Fourteen-year Anti-Japanese War are two concepts related to the process of War of Resistance against Japanese Aggression's anti-Japanese War from local to national. The eight-year war of resistance refers to the national war of resistance starting from 1937, and the fourteen-year war of resistance is the whole struggle against Japanese imperialist aggression, including the partial war of resistance starting from 193 1

These two formulations have been used in different occasions, different angles and different language environments, and have been established. Its essence is not contradictory. China * * * has always adhered to the anti-Japanese concept and played a mainstay role in different stages.

In 1937, we fully affirmed the national war of resistance under the banner of the anti-Japanese national united front advocated by China after the July 7th Incident, and in 193 1, we fully affirmed the anti-Japanese struggle led by China * * independently after the September 18th Incident, especially the heroic struggle of the anti-Japanese allied forces in Northeast China and the rising resistance of other China troops.
