The poem "Book Anger" expresses the poet's thoughts and feelings, which are both "grief and indignation" and "heroic". Although there is no word "anger" in the whole poem, it is indignant to savor it carefully. The first couplet recalls the past, shapes the poet's self-image in his early years, and secretly writes that he wants to recover lost ground. "Things are very difficult" implies that the capitulators took control of state affairs, paving the way for the subsequent "empty check". In the aspect of composition, the word "anger" in the poem title is pointed out, which constitutes the emotional tone of the whole poem. Couplets are composed of six nouns, which outline two magnificent and magnificent war scenes. This couplet inherits the "Qi Mountain", which more clearly highlights the poet's desire to serve the country and once again highlights the contradiction between ideal and reality. Compared with the first couplet, the feeling of grief and indignation is stronger. Necklace from memory to reality, poetry turns into sadness, "emptiness" and "already" set each other off into interest, infinite pain and grief. William's poet, based on his own situation, is determined to explore the north until his death, and his grief and indignation are full of heroic feelings.
