The 1980s witnessed the transformation of the research paradigm of the history of Chinese philosophy. During this period, FENG Qi and LI Ze-hou created two representative cases based on their different understandings of Marxism. While LI Ze-hou advocated "returning to historical materialism", FENG Qi constructed his "doctrine of wisdom". It is based on the "doctrine of wisdom" that FENG Qi's research of the history of philosophy has taken a unique intellectual approach and achieved its internal development. FENG first expounds the "logic development" of the history of ancient Chinese philosophy, then elaborates the "revolutionary process" of the history of modern Chinese philosophy, and finally extends to the history of intellectual trends in modern Chinese society.
