Abstract
Since the 50s to 80s of last century, political situation had changes as turbulent as the aesthetic practice of poetry on both sides of the Taiwan and China Mainland. Personal works have recorded a major change of every stage of the times. This period of poetry, even if not mainstream political poetry, still embody some quality we can call as "political rhetoric". Through the analysis on both sides of the main types of Poems (political poems, the military poets’ works, the underground poetry during the Cultural Revolution, Taiwan modernism poetry, poems at jails), I collect the political rhetoric devices they used on the theme of "violence". The political vision of the Taiwan poets have changed from the Cold War pattern which stress the crisis between "ourselves" and the "enemy", to an internal vision of "Governors- People", and political poetry was more cynical with a street style. Since the 80s, mainland poets’ sense of writing have shifted from "Political Poetics" to "Poetic Politics", from the conflicts between voices on the streets and voices underground, to the rhetorical exploration within the language. The distortion of these themes and styles appears more obvious and complex under the comparative vision of both sides of the Taiwan strait.
