The September 18 Incident broke out in 1931, and from then on Chinese people's nightmare of 14 years began. In the past fourteen years, the people of China have no livelihood, and the Japanese army has plundered property and resources on a large scale, which has made the Economic economy, which was already underdeveloped at that time, worse. So how much does Japan owe China?

First, Japan lacks resources and has coveted China for a long time
As an island country, Japan's small land area and lack of resources make it necessary for them to supply their own economic development by plundering the resources of other countries. In 1894, due to the corruption and incompetence of the Qing government, Japan finally won the victory, China and Japan signed the "Maguan Treaty", China was forced to cede Taiwan and other large areas of territory, coupled with the huge indemnities demanded by the Japanese army, the Chinese nation fell into a huge crisis, but also fueled Japan's ambitions to invade China.
In 1900, the Eight-Power Alliance invaded Beijing, and most of the troops sent by the Eight-Nation Came from Japan. These countries divided Beijing into regions, and Japan occupied the north of the East Fourth and robbed the Ministry of internal affairs of 3 million taels of silver. In addition to money, the coalition forces looted all the antiques and books in the Yuanmingyuan, and burned all those that could not be taken away; China was faced with a powerful foreign enemy and had no ability to fight back; this aggression further struck at China's national strength, and several successful invasions made Japan believe that China was only a local adult and was simply vulnerable.
The "Eastern Conference" held by Japan clearly pointed out that it would first occupy Northeast China and Mongolia, then invade and occupy all of China, and further conquer the whole world. In 1929, when Japan was affected by an economic crisis, the economic level declined, and industry and agriculture could not develop, at such a critical moment, they decided to launch a war of aggression to obtain resources.
Second, the War of Resistance Against Japanese Aggression was on the verge of breaking out
On September 18, 1931, the Japanese troops stationed in northeast China designed a trap, they blew up the South Manchuria Railway tracks they had built, blamed China, they pretended to be indignant, opened fire on the Northeast China Army, and the 918 Incident broke out. In this battle, the Northeast Chinese Army suffered more than 300 casualties, and the Japanese suffered only 24 casualties. In the face of foreign aggression, the Northeast Army chose the policy of "non-resistance", and Japan occupied the Northeast in one fell swoop.
On January 28, 1932, the Japanese army secretly attacked Zhabei in Shanghai, Jiang Guangding led the 19th Route Army to stubbornly resist, and the four general attacks of the Japanese army ended in failure. On February 14, Chiang Kai-shek ordered the Kuomintang Fifth Army to reinforce the 19th Route Army. Under such pressure, japan decided to truce the war in early March, and the two sides signed the Shanghai Armistice Agreement on May 5, which stipulated that Chinese troops withdrew from Shanghai and could not be fortified in Shanghai.
In 1935, Japan was not satisfied with occupying the northeast, and they carried out a series of aggressive acts in north China, collectively known as the North China Incident. At this time, the Communist Party had understood that in the face of foreign enemies, there could be no more civil war, and all the Parties in China must unite as one in order to confront the Japanese army. In 1936, the Gui Army led by Chiang Kai-shek and Li Zongren broke out the Liangguang Incident, and a civil war broke out. After the mediation of the Chinese Communist Party, the two sides realized that there should really be no civil war at this time, and the people suffered money and reached a peace agreement.
On July 7, 1937, under the pretext that a soldier was missing during a drill, the Japanese army asked to enter the city to search, but after the Chinese soldiers refused, the Japanese army launched an attack on Wanping City and Lugou Bridge, and the Lugou Bridge Incident broke out. The disappearance of the so-called soldiers is just a cover, the wolf ambitions of the Japanese army are clearly revealed, in the face of repeated aggression of the Japanese army, the two parties of the Chinese Kuomintang and the Communist Party reached the same front, since then, the eight-year-long War of Resistance Against Japanese Aggression has begun, and this war has brought huge losses to the development of the Chinese nation.
Third, the Japanese army did nothing wrong and plundered huge amounts of wealth
In addition to the "Maguan Treaty", Japan demanded a huge indemnity of 230 million taels of silver from China, and in the "Xinugu Treaty", the Japanese army claimed 35.577 million taels of silver from China, plus the million taels of gold and silver looted by the Japanese army in China and countless antique books, in these two wars of aggression against China alone, the Japanese army plundered nearly 300 million taels of silver from China.
After the fall of the northeast, they implemented the three-light policy: burning, killing, and robbing the light. Banks in the three eastern provinces were looted, and up to 140 million funds were looted. In addition to gold and silver jewelry, all kinds of rich mineral resources also made the Japanese army red-eyed, they snatched more than 3 million tons of steel ingots, more than 4 million tons of pig iron, more than 30 million tons of coal and more than 1.7 million tons of liquefied coal in the three northeastern provinces.
In the 14-year war of aggression against China, Japan seized 223 million tons of coal mines, 11 million tons of pig iron, 140 million cubic meters of wood and 5.8 million tons of steel in the northeast region, plus looting across the country, the Japanese army robbed a total of 640 million tons of coal, 200 million tons of rare earths, nearly 500 million tons of copper ore and 150 million tons of kaolin.
The Japanese army not only plundered mineral resources, but also 21,000 tons of gold, how could China at that time find so much gold? That is, even the money of the dead is not spared, the Japanese army broke into the homes of the people, wantonly robbed the property, even the funeral goods of the dead and even the gold teeth on the corpses, for the families who could not loot the money, they robbed the grain, in 14 years, the Japanese army robbed more than 800 million tons of grain, and a large number of people died in famine.
During the eight-year War of Resistance Against Japanese Aggression, the Chinese army suffered more than 3 million casualties, the number of ordinary people casualties far exceeded 8 million, the people without the strength of chickens were brutally tortured and killed by the Japanese army, the Japanese troops raped and plundered without evil, and everywhere they went, they were like locusts crossing the border, full of devastation. In the worst of the Nanjing Massacres, more than 300,000 ordinary people died, and Japan also created the plague virus, and countless people died from the plague.
In the War of Resistance Against Japan, China was robbed and invested in the war with more than 560 billion US dollars, which was undoubtedly astronomical for China at that time. After the victory of the War of Resistance Against Japan, such huge economic losses and casualties greatly limited China's development, and post-war reconstruction caused a considerable burden on the people.
In this land, the Japanese army has committed countless crimes, and now, China's development is no longer what it used to be, and people living in peacetime should never forget that today's happiness was bought by the tragic war of that year.
