The extraordinary ambition of the poet in this poem reflects the enterprising spirit of the people in the prosperous Tang Dynasty.
As far as the whole poem is concerned, this poem is said by the Japanese monk Konghai in On the Chamber of Secrets in the Mirror.
Some people say that poetry should not be reasonable. This should only mean that poetry should not be blunt, boring and abstract, not that philosophy cannot be revealed and promoted in poetry.
Just like this poem, it perfectly dissolves truth, scenery and events, making readers feel comfortable instead of reasoning.
This is a mode to express the philosophy of life through thinking in images according to the characteristics of poetry.
