The Mongolians in Kalaqin and other parts of Eastern Mongolia settled down early and switched from nomadism to farming. In the long and tortuous historical process of switching from hunting to herding and from herding to farming, the folk literature created by the people here is unique compared to the Mongolian folk literature in other regions, reflecting the distinctive characteristics of the intersection and integration of grassland culture and farming culture. The oral narrative method with Eastern Mongolian folk stories as the main style not only inherits the tradition of grassland nomadic culture, but also absorbs the nutrition of the farming culture of the Han nationality in the Central Plains with a broad mind, and has a full-scale and wide-angle reflection of the farming life after settling down, thus forming a cultural feature that is similar to but different from the folk literature of the Mongolian people in the grassland. Eastern Mongolian folk literature not only contains the ancient primitive worship ideas of the Mongolian people, as well as the nostalgia for the forest hunting and nomadic life in the early period of farming, but also has a large number of works reflecting farming life, conveying the love and yearning of the Mongolian people in this area for farming production; it not only describes the history of the interaction between the Manchu and Mongolian peoples in politics, economy and marriage in Eastern Mongolia over the past 300 years, but also presents a wide-angle presentation of the history of the cooperation between the Mongolian and Han peoples in farming and developing western Liaoning, as well as the integration of the cultures of the three ethnic groups of Mongolia, Han and Manchu. These oral narratives are of great reference value for studying the history and culture of the Mongolian peoples in Eastern Mongolia, such as the Kalaqin and Tumed, and examining the changes in Mongolian culture. Throughout the ages, there has always been a group of storytellers and singers who enjoy a high reputation in the local area active in the land of Eastern Mongolia. They have made great contributions to the prosperity of Eastern Mongolian folk literature. Their endless stories and folk songs reflect the unique simplicity and richness of Kalaqin folk literature, and show the world that Eastern Mongolian folk literature is irreplaceable in terms of its large reserves, rich content, wide range of themes, and distinct cultural personality. However, with the passage of time, the older generation of inheritors of Kalaqin Left-wing Mongolian folk literature have passed away one after another, and the genealogy of inheritance has been difficult to continue. Eastern Mongolian folk literature, which has important oral history value, is fading from people's memory. What is particularly worrying is that the recordings collected and recorded by local cultural departments in the past 20 years have begun to demagnetize and distort. The grassroots cultural departments in poor areas are helpless. Eastern Mongolian folk literature is truly in a serious endangered state and urgently needs protection and rescue.
