The famous line in this poem is: I am humble and dare not forget about my country, but I still have to wait for the coffin to be closed.

Brief analysis: These two lines of poetry are the main theme of the whole poem. These two sentences allow us to see the poet's noble personality and a loyal and patriotic heart. Precisely because the poet is upright and open-minded, he does not mind the temporary setbacks he encounters. He firmly believes that history is fair and will make an appropriate evaluation of a person. But the poet did not limit himself to expressing his own feelings, but took national affairs as his own responsibility.
