If what you were taught became reversed. I read some books which were written by authors of about 80 years old. They were elementary school children when World War Ⅱ was over. They experienced the same thing. They were taught by their teachers during the war that Japanese emperor was a god and they must fight against the U.S with their lives for him. However they were taught by their teachers after the war was over that Japanese emperor was just a human and the U.S was a friend who would teach us democracy, human rights and free. They say that they clearly remembered that immediately after the war was over, the considerable parts of school textbooks used during the war were painted in black with charcoal and their teachers taught them the opposite of what they taught during the war. They say that they can't trust nations and that they knew thought of people changes instantly from the experience. They worked hard and became a driving force for economic development of Japan. However they had the intensive experience like that when they were children. Can you guess if what you were taught became reversed.
