 Xie Lingyun (385–433) was considered a progenitor and major exponent of nature or landscape poetry focusing on the "mountain and streams", as opposed to Tao Yuanming and the "field and garden" type of Chinese landscape poetry.His poetry is allusive and complex, and uses a lot of imagery of hills and nature.Other important Eastern Jin poets include the 2 heroes of Taikang Lu Ji (Shiheng) (261–303) and Pan Yue (247–300), Liu Kun (劉琨), and Guo Pu (276–324), also Yan Yanzhi (顏延之, 384–456, so more often considered as Liu Song dynasty poet).
