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.
