The title of "History of High School" lists four heinous crimes committed by Japanese imperialism in China from19th century to 1940s.

Everywhere, 1895, the Sino-Japanese War of 1894-1895, Japan attacked Liaodong Peninsula, causing the Lushun tragedy. 1904, the Russo-Japanese War took place in the northeast of China. During the Russo-Japanese War, the northeast of China was the battlefield of land confrontation between the two sides. The local people suffered great disasters, and their lives and property suffered unprecedented havoc. The factories and houses in Lushun were bombed, and even the temples were not spared. Cattle were robbed, food was robbed, and hundreds of thousands of refugees were displaced. Both China and Russia forced the Japanese people to transport ammunition and labor for them. Many people died unjustly under the artillery fire of the invaders of the two countries, and even a large number of Japanese civilians were killed as "spies" by China and Russia. I remember it seems that Lu Xun abandoned medical literature because of this incident. 193 1 year, the northeast was completely occupied the year after the September 18th Incident, and Japan's 73 1 troops, Ishii troops, etc. They are all full of evil. The Japanese engaged in germ warfare, polluted rivers with bacteria and caused epidemics, then the Nanjing Massacre, and so on.
