Before I came into contact with history, I imagined that most of the fields have been cultivated, but later I found that this is not the case. Even for the tasks that have been very hot, you carefully study the existing research results and do with some related historical materials. By comparison, you will find that almost everyone, every history, has been neglected by historians, and there are a lot of gaps. The most accurate summary of the point of view of this text is. ['If you have a misunderstanding of history.', 'Historical research remains promising.', 'Current historical research results are relatively limited.', 'Discussion on the urgent need to strengthen historical research methods.']
