How did metaphysical poetry come into being?

The appearance of metaphysical poetry is closely related to the reality at that time. The Jin Dynasty moved south, and the combination of Zen and metaphysics strengthened the infiltration of metaphysics into literature, and metaphysical poetry gradually occupied a dominant position in the poetry circles of the Eastern Jin Dynasty. The metaphysical school, represented by Sun Chuo and Xu Xun, talks about Hyunri, which is not as good as benevolence and righteousness. This reason is too grandiose and tasteless. The metaphysical poetry of "quasi-morality" has ruled the poetry world for one hundred years. It was not until the appearance of Tao Yuanming and Xie Lingyun at the end of the Eastern Jin Dynasty that they injected new vitality and brought new changes to the poetry circles in the Eastern Jin Dynasty. Tao Yuanming's pastoral poems and Xie Lingyun's landscape poems respectively opened up a new field of China's poetry, showing a major breakthrough in the theme and style of China's ancient poetry.
