Hiding and nourishing yang is the deepest meaning.
The fire flared up again in spring,
The blazing stove blazed all night.
Ding yiyuan came to generate electricity,
The stone remains the same after death.
I hope all people are warm,
Take the trouble to walk out of the mountain.
-[Ming] Yu Qian
Appreciation: This object-chanting poem is the author's metaphor for coal, and every sentence praises coal. In fact, it expresses his ambition to devote himself to his country and die. The first four sentences describe the image and life of coal. The last four sentences express the poet's feelings of devoting himself to the country and the people. The poet cares about the country and the people all his life and takes rejuvenating the country as his own responsibility. His ambition is clearly pointed out in the last four sentences, especially his ambition of sacrificing himself for the public. The poet expressed his ambition in his poems: although the stone is hard, it still has the heart of benefiting the country and the people. Even though he went through all kinds of hardships, he was infatuated, not afraid of difficulties, and gave his life to serve the country and the people. Look at the current civil servants, shouldn't they pretend to be "coal"?
