Transformation is one of the significant features of modern poetry, and it makes the most use of abnormal formation, which is seen as a sort of metaphor called ”Yuan Chi Pi”. The purpose of transformation is to break the natural link between languages. A good transformation can not only change the formation of the signifier but also the signified and to make it more metaphorical. Transformation of poetic languages brings both beauty and eeriness. However, in order to avoid too much transformation, some people insist the languages should be untransformed, less transformed or even de-transformed. Transformed or not, the use of language has better be poetic and tense enough.
