Where do the two sides of the Yellow River recovered by the imperial army express their joy in this poem?

Picking thistle north; It expresses the poet's ecstasy, and shows the poet's thoughts and feelings of longing for national unity and loving life.

On hearing the news of "picking chrysanthemums under the east fence", the poet "couldn't stop crying on my coat at first"-he wept for joy and wrote down happiness with tears in his eyes, which is the most vivid portrayal of the intersection of joy and sorrow.

"However, I packed my books and poems crazily"-from crying with joy to being overjoyed, wrote the ecstasy that the poet could not express in words at this moment.

"Sing my songs loudly and drink my wine deeply"-from exultation to singing loudly and drinking too much.

"In the green spring, I began to go home"-from ecstatic to homesick. The last two sentences are still written as "going home", which is a concrete way to go home in imagination, and people want to see the anxiety and joy of the poet anxious to return.

The whole poem is joyful from beginning to end, which always gives people a strong pleasure.

The whole poem is full of unrestrained emotions and the word "hi" is everywhere, which vividly expresses the author's infinite joy and excitement.
