/kloc-After the Opium War in the 9th century, Japan launched the Sino-Japanese War of 1894-1895 against China. After the defeat of the Qing Dynasty, the Japanese demanded that China cede the three northeastern provinces because of their rich resources. Because western powers, including Russia, Britain, Germany and other countries, were afraid that Japan would become too powerful and opposed it, Japan's attempt failed. In fact, the Japanese plot to invade China has been going on for at least 60 years.

After the September 18th Incident, Japan occupied the three northeastern provinces of China, and then moved a large number of Japanese to this area. These Japanese also include many technicians, who have built many military equipment production factories to manufacture trucks, guns, tanks and planes.

The deliberate purpose of the Japanese is to turn northeast China into its largest arsenal, providing munitions for wars in other parts of China and Southeast Asia. In fact, the weapons and fuels used by the Japanese army in China and Southeast Asia are basically manufactured in the northeast of China. He said that from 193 1 to 1937, the Japanese produced a large amount of arms in the northeast of China, which was too much to store. It is against this background that the Japanese launched the "July 7th Incident" and launched a full-scale war of aggression against China to realize their ambition of occupying China and enslaving the people of China.
