What is the artistic conception of In the Lodge of Herons?

The poet stood on the stork building, looked at the birds in the sky as if they were downstairs, and felt that he was far-sighted and detached from the world. Looking from the stork tower, it seems that the natural situation should be that continuous mountains surround the plain fields, but the roaring Yellow River splits the mountains and flows into the broken mountains. This poem has a magnificent artistic conception and is a masterpiece describing the scenery of the mirage.
