The artistic expression of poetry is successful.
The first sentence is unremarkable, with no trace.
The tone of the second sentence suddenly rose, and the melody suddenly accelerated, forming a climax.
The third sentence is transition, which is posturing. The fourth sentence, plummeting, such as thousands of feet hanging waterfall falling into a deep pool, came to an abrupt end. What a big ups and downs, what a strong ups and downs, from "Zhenlin robe" to "Standing in silence", "more is told in silence than in voice".
It is in this ups and downs that great artistic effects have been achieved. The language of poetry is as clear, plain and natural as words.
Probably the poet thinks that only such a poem can better express his temperament! By the way, this is an ancient poem. The difference between ancient Jue and modern Jue (called law Jue in ancient times) is that the former uses more rhymes and does not pay attention to the flat and even format, while the latter is.
This poem is ancient and unique because it uses rhyme and does not pay attention to flatness.
