Abstract: It is difficult to give a fixed pattern of poetic style of vernacular verse and to form the style. There were too many revolutions and wars during the 20^th century in China. Vernacular verse has carried too much non-poetic function for a long time. It was born in the unfortunate time and grew up in adverse circumstance. There were almost no good circumstance for the poets of aestheti-cism to build poetic style. The construction of poetic style of new poetry has always been in extreme condition of more conflicts and less compromise between the liberalization of poetic style and the rule of poetic style, thus resulting in an unhealthy style. The first half of the 20^th century, especially the first and second decades, is the worst period of the construction of poetic style of new poetry.
