What are the similarities and differences in creative themes and artistic styles between Tao Yuanming's pastoral poems and Xie Lingyun's landscape poems?

After Tao Yuanming, a great poet in the Eastern Jin Dynasty, founded the pastoral school, the pastoral poems in the Tang and Song Dynasties mainly became poems written by reclusive literati and officials who retired from officialdom to the countryside to describe rural life. During the years of Kaiyuan and Tianbao in Tang Dynasty, pastoral poetry and frontier poems were called two major schools of poetry. The former is unpretentious, while the latter is heroic. As for landscape poems, they refer to poems describing landscapes. Although poetry is not necessarily purely about mountains and rivers, there may be other auxiliary motifs, but the main purpose of the poet's creation must be to present the beauty of mountains and rivers seen by the eyes and ears. Created by Xie Lingyun, it was born out of metaphysical poetry. See:/qk/82725x/qk/82725x/200308/8402679.html for details.
