First of all, the Soviet Union and Japan were enemies. Although there was no war between the Soviet Union and Japan in World War II, in the Russo-Japanese War of 1904, the Soviet Union suffered casualties of 16000 and captured 80000 people. This is a great loss. 1939 battle, the Soviet army killed or injured nearly 30 thousand people. Especially in the battle of Nomenham, Japan used chemical and biological weapons to pollute the water source of the Soviet Union. Although I finally smashed my own foot, it made the Soviet Union very angry, and the Soviet Union would definitely retaliate if it had the chance. After being brought back to the Soviet Union, these prisoners of war were allowed to go out to complete their tasks during the day. They can have a rest after the task is completed. Their task is simple, they don't need brains, they just need to participate in their daily work.

The daily work of Japanese prisoners of war is very hard, including mining, road construction, construction and coal mining. No matter how tired you are, if the task of the day is not completed, there will be no food to eat. The Soviet Union cruelly squeezed the use value of prisoners of war. Because too many people died in the war and there was a serious shortage of domestic labor, the Soviet Union treated Japanese prisoners of war this way. However, after the initial crazy squeezing, the Soviet Union gradually found that its dissatisfaction with prisoners of war was increasing. In order to prevent them from rebelling, the Soviet Union will give them ideological and political education.

They arrange teachers to instill Soviet ideas in prisoners of war every day. Once some prisoners of war have passed the ideological and political examination, they will get better treatment, and those with impure ideas will continue to instill ideas in them until they realize. In this case, the thoughts of Japanese prisoners of war have been completely sublimated. In the following years, even a group of prisoners of war returned to China and became excellent spies of the Soviet Union. Although Japanese prisoners of war were saved, most of them were still miserable. In cold Siberia, they work year after year. Countless Japanese people paid the price for their mistakes. Countless people were frozen, starved and even died. 1956, the Soviet Union began to repatriate Japanese prisoners. When they arrived, there were 600 thousand, and when they returned to Japan, there were only 390 thousand, and there were several ships' ashes. The Soviet Union unilaterally said that only five people died.
