Guo Moruo is an unavoidable and indelible figure in the history of Chinese historiography in the 20th century. His lofty academic status is determined by his outstanding contributions. Scholars with high attainments in history, archaeology, ancient philology, antiquities, literature, art and so on. There were few scholars of China history in the 20th century, and even fewer before the 20th century. The "reflection" on Guo Moruo actually involves how to understand the cultural development path of China in the 20th century, that is, what is the outstanding cultural heritage in the 20th century and what is the cultural development direction of China in the 2nd/kloc-0th century. The evaluation of Guo Moruo should be like the evaluation of any historical figure, adhere to scientific theory and methodology, adhere to the principle of "knowing people and discussing the world", and should not be divorced from certain historical conditions, but should focus on revealing the essence and mainstream. If the positions of the mainstream and tributaries are reversed, the tributaries are infinitely exaggerated, and even vilified and abused, it will deviate from the principles and methods that should be used to evaluate historical figures; This is the same as the practice of infinitely touting a historical figure, which is not desirable.
