Lu you
When I was a child, I knew that the world was unbearable and the Central Plains looked like a mountain.
It snowed all night in the building, and the autumn wind dispersed in the iron horse.
Stuck on the Great Wall, I promised myself that the sideburns in the mirror had faded long ago.
A teacher showed his real name, but after a thousand years, no one can compare with him.
My friend, this is a poem. You shouldn't ask this question. Rhetoric can be asked by big rhetoric and small rhetoric. It is estimated that what you are asking is rhetoric in a narrow sense, and rhetoric in a narrow sense should be implemented in specific sentences. Let's just answer:
The north of the Central Plains looks like a mountain: this sentence is a metaphor, which is used to make the object of description vivid, meaning that Lu You's lofty ambition to recover rivers and mountains is as lofty as a mountain;
There is nothing to say. Lu You described two successful anti-Jin struggles here, which showed that the Song people had the ability to defeat the Jin people, and expressed their desire to join this kind of struggle and their indignation at the inaction of the court.
Climbing the Great Wall is an empty promise, but the temple in the mirror has been discovered first: this sentence is also dual, but it also has metaphorical meaning. Unfortunately, climbing the Great Wall is an empty expectation. Doing nothing, ambition is hard to pay, and there is a kind of grief and indignation that "the heart is in Tianshan Mountain and the body is in Cangzhou";
A teacher shows his real name, and after a thousand years, who can be an equal with him: Zhu Gekongming was quoted as a teacher in the previous sentence. Zhuge's ambition of "commander in chief of the three armies, setting the Central Plains in the north" made the poet envious. The suggestion of "being a good minister and staying away from villains" is the poet's wish, and the spirit of "doing your best until you die" is used by the poet to encourage yourself. However, all this is true. It means that no one can compare with it for thousands of years, and no one can compare with it. If I can show my ambition and pay the price for it, then I am the one who can be famous for it for thousands of years.
In this sentence, the poet once again expressed infinite grief and lament.
In fact, if poetry analyzes "rhetoric" in this way, what's the point? What a teacher's ghost problem!
