Cao Pi’s Dian Lun, Lun Wen play an important role in Chinese literary critcism history. Beginning with the analysis of the psychology of Cao Pi’s purposing to usurp the kaiserdom of the Han Dynasty, and following with the analysis of the characteristic of Wei Dynasty, this article draw a conclusion that Cao Pi’s judgment which improved the degree of literature and aggrandized the function of it, not purposing to discuss literature, is to advise intellectuals not to choose “Achievement Establishing” as their human ideality, between “Virtue Establishin”、”Achievement Establishing” and “Opinion Establishing”, and to change intellectuals’ mind on the be somebody or to do something. Cao Pi tried to transfer intellectuals’ attention from taking part in politics to writing for renown and eternity. If intellectuals could face the politics with a kind of detached attitude, his usurpation world decrease lots of pressure from discommenders. This conclusion is very different from the established illumination on Dian Lun, Lun Wen, but accords with the principle “Know the man, understand the time”. In the intricate politics of that time, Cao Pi’s intention met with the rejection of intellectuals, for example, Zao Zhi deliverede oneself of the contrary standpoint, followed by the avoidless discordance between brothers.
