Your knowledge of what Chinese people care, know and don't know is very shallow. Why don't you go to your classroom today and tell your Chinese students that the Japanese were good in China and that China was wrong in getting involve in the Korean war. Your student will throw your rotten tomatoes and you will be fired from your school in a second. Sad how little you know about the Chinese. Here is some history for you, almost half of the Chinese Army sent to fight to Korea were young Chinese women like the one in the picture below. I hope this help you understand more the Chinese people.
