The Liao Dynasty made indelible contributions to the development history of the Chinese nation,but its literature,especially the unique literary form of Liao poetry,is almost blank in the vast sea of an-cient Chinese literary works due to the scattered historical materials.In response to this situation,this ar-ticle systematically explains the basic content and composition of Liao poetry based on existing works and scattered chapters,and explores the characteristics of Liao poetry.It also sorts out and analyzes the his-torical value of Liao poetry in politics,culture,folk customs,religion,and other aspects,in order to lay a foundation for the study of literature and Liao poetry in the Liao Dynasty.
