Abstract: Literary forms are by nature a linguistic system.Although all of the literary texts of ancient China possess the chance to create Yixiang ( a particular scene which makes a text become a literary one) from the grammatical perspective, they do not usually take it  as their purpose to produce a particular Yixiang. For instance, the ancient prose is not fit to generate Yixiang. Only the changed forms, Fu(赋) , Ci( 词) , Qu(曲) , and Poem( 诗) , by their particular grammatical system, can generate Yixiang.

Key words: Yixiang, literary form, grammar
