What is the artistic conception of pastoral poetry?

China's ancient pastoral poems refer to poems praising rural life, which mainly show the rural scenery and the labor of farmers, shepherds and fishermen. After Tao Yuanming, a great poet in the Eastern Jin Dynasty, initiated the style of pastoral poetry, the pastoral poetry in Tang and Song Dynasties mainly became pastoral life poems written by recluse literati and retired officials. Landscape pastoral poetry and frontier fortress poetry are also called the two schools of Ci in Kaiyuan and Tianbao years of Tang Dynasty. The former is unpretentious, while the latter is heroic.
