During the Japanese invasion of China, the Japanese army arrested hundreds of Chinese, but left people with deep pain without beating or cursing
In 1937, the Japanese officially fully implemented the invasion of China, although before this, the Japanese had already occupied the northeast, at that time the Japanese had been testing the bottom line of the Chinese, and had not harmed the Chinese people, until the Japanese discovered that the Chinese warlords were greedy and afraid of death, And Zhang Xueliang did nothing, the Japanese occupied the three northeastern provinces!

During the war of aggression against China, the Japanese used to let the Chinese not resist, so they gave the Chinese people a lot of candy to eat, for example, the Chinese people at that time have always been rebelling against the rulers of the Qing Dynasty, so who will be the emperor of the people, there is not much difference for the people, as long as it can be really good to the Chinese people, then even if the Japanese occupy China, for many ordinary people, it is actually the same, but the facts have proved that The actions of the Japanese were even more fierce than those of the Qing rulers at that time!
The Japanese once talked to the Chinese people about a condition, that is, the Japanese will build new factories and schools in China, hoping that the Chinese people, like before, can enter their factories to work, and will pay the Chinese people a certain wage, and the Japanese schools are still free for the Chinese people, so the soft-hearted Chinese people naturally listen to the Japanese rhetoric, but who will know, when they enter these so-called factories and schools, it is like being put in prison. The Japanese army effortlessly captured hundreds of Chinese, so what did they want to do when they captured these Chinese? In fact, the Japanese army did not scold Chinese, but their actions left countless Chinese with deep pain, and then people were indignant!
The famous 731 unit was established at this time, Japan's technology at that time was already very advanced, at least relative to China, and the Japanese army also knew that once the Chinese resisted, the Japanese army would inevitably be driven out of China's territory, so they hoped to create some pills, which could be easily killed without using force,Chinese and then all the Japanese would be moved to China's territory to live. So they conduct human research experiments in these so-called factories, and many Chinese people act as guinea pigs for experiments, and eventually die miserably!
