It was an incident in which the Japanese Kwantung Army stationed in the northeast of China suddenly attacked Shenyang on September 193 18, 2008 and occupied the northeast by force. The September 18th Incident was a war of aggression against China deliberately created and launched by Japan. It was the beginning of Japanese imperialism's attempt to conquer China by force, the starting point of China and War of Resistance against Japanese Aggression, the beginning of China's local war of resistance, and the prelude of the Eastern battlefield of the Second World War. After the September 18th Incident, China people's local war of resistance also marked the starting point of the world anti-fascist war.

1931September 18 night, the Japanese kwantung army, entrenched in the northeast of China, blew up the Japanese South Manchuria railway track built by the railway "guard" near Shenyang Liutiao Lake and blamed it on the China army. Using this as an excuse, the Japanese army shelled the North Camp of the Northeast Army in China, creating the "September 18th Incident" that shocked China and foreign countries. The next day, the Japanese army invaded Shenyang and successively invaded the three northeastern provinces. 1February 932, the whole northeast fell. Since then, the Japanese puppet Manchukuo regime was established in the northeast of China, and began to enslave and colonize the people in the northeast for 14 years, making more than 30 million compatriots in the northeast suffer from conquered people.

The July 7th Incident, also known as the Lugouqiao Incident, took place on July 7th, 1937.

1On the night of July 7th, 937, the Japanese army in Lugouqiao held a so-called military exercise near the military position in China without informing the local area, falsely claiming that a Japanese soldier was missing and asked to enter wanping county (now Lugouqiao Town) in the southwest of Beiping, but was sternly refused by the China garrison.
