This term refers to the state of mind in which external things evoke one’s inner feelings, thus creating aesthetic appreciation. As an aesthetic term, evocation means both stimulation and association. In artistic appreciation, Confucius（551-479 BC） used evocation to refer to the psychological effect and educational function of reading poetry, and it was not meant to be a literary term only. In artistic creation, evocation means association, which is among the six poetic forms, namely, ballads, narratives, analogies, association, court hymns, and eulogy, as described in The Book of Songs. The first three refer to the content and subtypes of classic Chinese poetry, whereas the latter three elements are creative means employed by The Book of Songs. Evocation is defined by the use of similar or relevant things to create a metaphor which, by virtue of imagination and association, conveys a message through imagery and highlights the nuances of poetry. Evocation arouses one’s imagination through reading a poem, making such experience an enjoyable one. It is a rhetorical means frequently used in classical Chinese poetry. At first, evocation was closely linked to analogy. Its implication and aesthetic properties started to grow independently in the Wei, Jin and Southern and Northern Dynasties period, and finally became a poetic term different from analogy and association. Evocation focuses on the impact of external things on one’s emotions.
