The poetics of Yang Weizhen 杨维桢， influenced by the twisted mentality of being frustrated for his talents，is a combination of multiple contradictions： the contradiction between the pursuit of Bixing 比兴 and allegory and advocating a grotesque poetic style in the creation of Yuefu 乐府，the entanglement between the generality and individuality of disposition in poetry concepts，and the opposition between the Tieya Style 铁崖体 and the Xian Style 纤体 in the poetic style. Generally speaking，there is a huge aesthetic difference between the Tieya Style based on Yuefu and the Xian Style based on styles of Zhuzhi 竹枝，Xichun 嬉春 and Xianglian 香奁. As a result， Yang Weizhen’s poetics is rich in connotation and full of tension，causing controversies in the evaluation in the aftertime.
