Compare the motherland to a "girl" and her patriotic spirit in full swing to "coal in the furnace", which has been buried underground for a long time. Comparing myself with coal, I first expressed my dissatisfaction with the long-term burying of talents in the old society. Once coal is ignited, it gives off light and heat without reservation. Compared with the burning "coal in the furnace", it is very appropriate to express the poet's unreserved dedication, and the coal in the furnace not only shows love, but also shows dedication. There are two terms that are appropriate and reasonable. Therefore, the poet's unique choice of images in this poem is unique.
2. How to understand "I live up to your kindness and you live up to my heart."
The first sentence is about the motherland's kindness to the poet, which is the basis for the poet to miss the motherland. Because we are using the metaphor of "young girl", we also use the metaphor of "hospitality" here. The word "worthy" expresses the meaning of service. The "thinking" in the latter sentence not only refers to the yearning for the motherland as a geographical concept, but also the yearning for mountains and rivers, which is an expectation with deeper meaning. I hope the motherland will continue to develop, be strong and make progress, so I use "Don't let it down".
3. How to understand the predecessor, past and present of "coal in the furnace"?
In the third section, the last three lines of the poem write "my predecessor", which are the past and the present respectively. The predecessor of coal used to be a useful pillar. It was buried underground for many years, and now it's going to be seen again. Literally speaking, it is about the formation process of coal, and its deep meaning is that I was originally a useful talent of the country, but under the oppression of the dark reality in the past, my patriotism was buried deep in my heart, and I couldn't express it, but I didn't want to serve my country. At present, under the impetus of the May 4th Movement, the motherland glows with new youth, and the poet's patriotic feelings burst out irresistibly, and it is finally time to serve the motherland.
