Although it is difficult to leave his hometown, the poet will eventually regain his ambition, put his ambition above the affair of his children, and not think about the heir of his family. Finally, he shows his heart: "When the soul returns, the flag will be empty." As the poet said in "Mother in Prison", "In twenty years, Chun and the first bell will be Beisai." This poet, who knows the spring and is close to the road, calmly made a plan of "returning to heaven on one slope", determined to die indomitable, resolutely regained his sight, and failed to complete the great cause before his death. After his death, he should personally see his successor lead the uprising to restore Daming Mountain. The poem ends with a resounding clank oath, which clearly shows the poet's unyielding fighting spirit and sincere feelings of serving the country, deeply encourages his successors, and sets up an immortal monument for readers with the interests of the country and the nation above all else.
