How did China treat Japanese orphans, prisoners of war and immigrants after Japan's defeat?

Some of them were repatriated, such as prisoners of war, and some orphans were raised by China people. The TV also reported Japanese orphans who were in China at that time. Now they are about sixty or seventy years old. When interviewing them, I interviewed them in fluent Chinese, and then they thanked their Chinese mother for raising them. China people still attach great importance to affection and righteousness.
