As the "hero of jian an",cao zhi played an important role in the jian an period and the whole history of ancient Chinese literature.The study of cao zhi and his works has never been cut off.Cao zhi’s works are rich in categories and high in quantity and quality,while his yuefu poems take a large proportion in his poems and have high achievements,which cannot be ignored.The most frequent and thorough research on cao zhi’s yuefu poems is the literatization of his yuefu,that is,the innovation of his yuefu poems.However,his literary achievement was not achieved overnight,but based on the further exploration on the basis of predecessors.Therefore,this paper takes cao zhi’s yuefu poetry as the research object,takes the simulation and acceptance of the works of the previous generation as the focus,and focuses on the innovation of cao zhi’s yuefu poetry,namely its characteristics.This thesis takes cao zhi’s yuefu poetry as an independent research object,which is divided into four chapters.The first part is the introduction,which mainly describes cao zhi’s life experience,research status and research results of cao zhi’s works.First of all,the introduction of cao zhi’s life story is helpful to understand the reason why his yuefu poems were created almost in the later period.Secondly,a summary of the academic research on cao zhi is helpful to clarify the various aspects of cao zhi’s literature research and to determine the academic significance of this topic.The first chapter introduces the existing situation of cao zhi’s yuefu poems and the historical background of his yuefu poems,focusing on a clear definition of the existing yuefu poems of cao zhi and an analysis of the reasons for cao zhi’s creation of yuefu poems.The second chapter mainly deals with the themes and contents of cao zhi’s yuefu poems,and divides them into four categories: banquet poems,female poems,fairy poems and epic poems.The third chapter discusses the acceptance of cao zhi’s yuefu poems to the yuefu of the han dynasty,respectively from the acceptance of the yuefu of the han dynasty,the acceptance of cao cao and the influence of the literati of the same period,and then preliminarily discusses the reasons for the simulated acceptance of cao zhi’s yuefu poems.The fourth chapter discusses the characteristics of cao zhi’s yuefu poems from the aspects of the use of allusions,the conversion of vulgarities into elegance,and the musicality,which is conducive to an in-depth understanding of his yuefu poems.
