The Course of Beauty is a bird's eye view of China's literature and art for thousands of years. Some important concepts, such as "flying while flying", "hideous beauty", "Confucianism and Taoism complement each other", "human awakening", Buddha sculpture, landscape painting and so on, have never been seen before.

On the basis of traditional theories, Chinese aesthetics talks more deeply about the non-Dionysian characteristics of China culture, emphasizing the blending of reason and desire. These two books constitute the internal and external parts of the author's history of Chinese aesthetics.
