For a history topic， the studies on Nanking Massacre have been experienced for more than 30 years by Chinese scholars with rich achievements. It is a series question for how to put this study forward. I think we should make some breakthroughs on research methods and carry out cross-subject studies. Specially， we should transfer our studying thinking from grand narration to individual studies； from the injured side to injuring side or the other sides. We should also open up new research areas， search for new research materials. We must carry out the studies not only from history， but also from many other subjects. If we work hard， I’m sure we can advance the important studies， which is relate to our nation’s traumatic memory， current politics and diplomacy.
