The Time-Space Metaphor of Frontier Fortress in the Silk Road Poems of the Tang Dynasty

摘要

As a crystallization of human wisdom, Tang poetry usually uses metaphor to create unexpected artistic conception and expression effect. It is the essence of Tang poetry. This paper explores the functional interpretation of the time-space metaphor and image in the silk road poems of the Tang Dynasty. Based on the time-space cognitive rationale in the construction and interpretation of the image metaphor of Silk Road poetry, it is argued that the frontier poetry is the conclusion of the rise and fall of the epic silk road.
