Although research on metaphors has gained popularity in Taiwan, most of the studies pay attention to just the rhetorical function of metaphors.Actually, language carries literature, If not through language, the meaning and beauty of literature can not be fully expressed on its own. The same for metaphor studies: Studying only from the literary or the linguistic point of view is never enough.So, this paper will start from the philological perspective and hope to answer the following three questions：1) What is the difference between literary metaphors and linguistic metaphors? 2) How does one classify the different kinds of metaphors? and 3) What functions can metaphor have in different contexts?
