Fan Wenlan put forward four problems in studying history: learning theory, mastering materials, expressing words, and matching words with deeds! It can be seen that the theory is the first, that is, Marxist theory, paying attention to the credibility of historical materials, rigorous research, and pertinent evaluation!

Bai Yang's historical research and writing techniques are vivid in words, beautiful in language, rich in literary talent and fascinating. Secondly, he is innovative in the method of narrating history. For example, the Outline of China People's History is divided into chapters with "century" and chapters with questions, giving people a lively feeling. Its evaluation is subjective, with a strong color of personal criticism, and it is more to explain its views through history, especially the research and discussion of "people"!

The above is just a personal opinion, let's discuss it together!
