This term refers to an effect that allows lasting satisfaction and rewarding in poetry appreciation, which is a particular sense of beauty offered by poetry. In the Southern Dynasties, poetry critic Zhong Rong proposed in “The Critique of Poetry” that in writing five-character-per-line poems, one should pay special attention to the combination of form and content, so that readers could enjoy a poem with inexhaustible delight. Later, nuanced flavor also came to refer to a kind of taste in literary and artistic creation.
Five-character-per-line poems constitute the most important poetic form and are most richly imbued with nuanced flavors. (Zhong Rong: Preface to “The Critique of Poetry”)
A literary work cultivates the mind, implicitly satirizes or criticizes a monarch, and enables the reader to obtain a sense of aesthetic appreciation. Reading such works gives one great delight. (Yan Zhitui: Admonitions for the Yan Clan)
