On one hand, the integration between literary autonomy and social heteronomy is the abscissa of the coordinate axis. On the other hand, the integration of ancient and present poetic resources, and Chinese and western poetic resources is the ordinate of the coordinate axis. Integration in Wu Mi\'s poetic thoughts is embodied in two aspects: Firstly, it means the integration of ancient and present poetic resources, and Chinese and western poetic resources. Wu Mi maintains that various poetic resources should be treated equally so as to find the similarities and differences among them. Only with a broad cultural view and calm attitude toward various poetics resources can a new system of modern poetics be achieved.
