Why do girls in ghost towns speak Chinese?

There are Koreans, Koreans and Japanese comfort women. A woman is the sister of a Japanese soldier. As a result, the soldier was beaten and his sister was transferred to continue to be a comfort woman.

At that time, in the middle and late period of this war in Japan, no one had the ability and dared to take the initiative to stop, and no one could be the master of this country. Many officers and men and people are crazy, and the war can only end if it is burned out. Whoever dares to stop, it is estimated that he will be hacked to death with a disorderly knife. If you don't fight, someone will fight, and whoever flinches will shoot.

Correspondingly, in China, War of Resistance against Japanese Aggression is also deeply rooted in people's hearts. Who dares to shout not to fight against Japan and hack to death?
