Although China was poor and backward in the 1930s and 1940s, there were also 40,000 people living on the land here. During the War of Resistance Against Japan, japan deployed more than 2 million people on the mainland, and these more than 2 million people were scattered in many counties. So a strange situation arises.

At that time, there were at least 10,000 people in a small county on the mainland, while Japan's military strength in some non-military places was generally only about 100 people. In Shangsi County, Guangxi Province, only 6 people were deployed.
But with these 6 people alone, they have properly obtained this small county town. So what made hundreds of thousands of people in this small county town afraid of these 6 Japanese troops? The reason is nothing more than that.
The first reason comes from psychology, which is the well-known "prisoner's dilemma" psychology. The Japanese even took advantage of the shortcomings of the humanity of ordinary people in the city and manipulated them tightly with suspicion and fear. As the saying goes, the gun hits the head bird. If everyone resists together, then the leader will die, and others will not die easily, but everyone expects others to lead. In fact, this kind of psychological process has appeared many times in ancient history, such as the shocking record of Liu Yu, the Emperor of the Song Dynasty of the Han Dynasty, who single-handedly killed thousands of people. It is also used in contemporary times as the subject of many films, such as the well-known American horror film Chainsaw Horror.
The second reason is Japan's high mobility. After experiencing the Meiji Restoration, Japan took the opportunity to catch up with the wave of scientific and technological revolution, the level of modernization was relatively high, and the level of mechanization at the army level also developed very rapidly. Therefore, after the Japanese captured a certain province, they improved the local transportation system as soon as possible, in order to better improve the efficient relevance within the Japanese army. This is why the armed forces behind enemy lines on the mainland usually target railway and road lines. Therefore, to some extent, a large number of Japanese people use these small county towns as sentinel bunkers, not to better manipulate them.
The third reason is the huge number of puppet troops under the control of the Japanese state, and although there are few Japanese in many urban areas, there are many puppet armies. The Japanese used hierarchical supervision to control them, to help the puppet army, and then used them to maintain discipline within the prefecture. It is precisely because of the help of this puppet army traitor, coupled with Japan's own increased firepower points, that Japan can have the vitality to supervise such urban areas at a very large level. Even in the face of large-scale peasant revolt resistance, Japan was able to hold out until reinforcements arrived.
Naturally, there are indeed many instances of resistance during the period. But if you think about it, even the regular troops of the Nationalist government can't defeat the regular troops with many times the military strength of Japan, let alone the ordinary people with their bare hands? However, it was also because of the poverty of the human resources of the Japanese state itself that the shortage of military strength was more obvious in the late stage of the War of Resistance Against Japan, so that most of the regions were in the situation of vacuum pump rule, which not only produced great convenience in the anti-Japanese war behind our enemy lines, but also gradually put the Japanese invading army in the Jedi.
