What are the artistic features of lime kiln?

This poem of chanting things is the author's self-metaphor to express his ambition of serving the country and the people. The first sentence: chanting coal. The second sentence: express your feelings positively, saying that it contains the yang of governing the country and reassuring the people. The deepest meaning highlights the profound meaning of this key point. Spring wrote "Yang and light break the night". This shows the strength of getting rid of the old cloth. The ancients called the temple prime minister Ding Miao. It is said here that the prime minister's actions depend on his ability to generate all things, and he is compared with coal. The third sentence: "Iron Stone" expresses his firm determination, which is also a portrayal of Yu Qian's personality. The fourth sentence: "I hope all the people have enough to eat and wear warm clothes" will further grow out of coal. In other words, the original intention of Du Fu's sentence expansion, that is, to go out to help the world, is to express his ambition. To sum up, the first four sentences describe the image of coal, and the last four sentences express the poet's feelings for the country and people after his life. The whole poem uses objects to express his ambition. The poet cared about his country and people all his life, and the last four sentences clearly pointed out his ambition. He sacrificed his ambition for the public, especially in the last two sentences. The poet expressed such an ambition in his poems: although the stone is hard, it still has the heart of benefiting the country and the people. Even through all kinds of hardships, he will remain infatuated, not afraid of difficulties and sacrifice himself for the country and the people.
