In the third chapter of Mei Ling's poems, he used the saying that he went to Taiwan to recruit old men to behead Yamaraja. What are the special expressive effects of these words in his poems?

There is nothing in it. There is no fountain or Yamaraja, but it can strengthen feelings and show determination to cut it. If you die, you will go to hell for revolution. Do you think Marshal Chen's revolutionary will is strong? If we can get out of danger today and work harder for the revolution in the future, we won't have such strong feelings, will we?
