Li Hu published An Outline of the Stages of Ancient Chinese Society and Its Social Nature: With a Discussion of the Principal Social Contradiction in Traditional China (the Outline) in No.1 of Journal of Literature, History and Philosophy in 2020. With concepts of local vocabulary, the Outline gives a comprehensive, systematic and indepth explanation of a major theorical and practical question in historical study regarding the staging of Chinese ancient history and its social nature. It has made a pioneering contribution to constructing an ancient history discourse system with “Chinese characteristics, Chinese style, and Chinese mode” (“the Three Chinas”) and to controlling the power of discourse in ancient history study. The Outline advocates clarifying the right and wrong of “borrowed” discourse, which is the premise of establishing the historical discourse system with “Three Chinas.” The Outline advocates accurately revealing the particularity of the contradiction in ancient Chinese history, i.e., “power is the dominant cause of ancient Chinese society” and its main contradictory relationship, which is the foundation of constructing the historical discourse system with “Three Chinas.” The Outline advocates the use of native words and expressions, which is an important carrier and necessary part of constructing the historical discourse system, and it has taken a substantial step in it. The Outline and its academic contribution show that the use of native vocabulary concepts not only helps to construct the ancient history system of “Three Chinas,” but also helps to control the historical discourse power.
